The Claws of Axos (TV story)

The Claws of Axos was the third story of season 8 of Doctor Who. It was the first story written by Bob Baker and Dave Martin, who stayed with the series until the end of the 1970s and created K9.

The Claws of Axos was the third story in the season long "Master arc". It saw the introduction of Axos. Despite its popularity, Axos did not again appear in the Doctor Who universe until the Doctor Who Magazine comic story The Golden Ones in 2010. Thus far it has not appeared in any other television stories, although it was mentioned on screen occasionally.

This story's events led the Doctor to strike a deal with the Master, who was unusually placed in a position of distress. With his help, the Doctor was able to restore his TARDIS back to working order, only to discover the High Council of Time Lords had programmed it to always return to Earth no matter how many times he could attempt to leave. He also revealed that the Time Lords had blocked his knowledge of dematerialisation theory.

Synopsis
A group of gold-skinned aliens land on Earth and offer wondrous technology in exchange for fuel. The Doctor, however, isn't fooled, uncovering the Axons' true nature and once again facing his arch enemy, the Master...

Episode one
UNIT's radar control pick up what they think is a comet however it alters course and is on a collision with Earth.

A large breathing aquatic looking creature approaches Earth.

Mr Chinn - the head of a committee inquiry into UNIT - is demanding to see papers in relation to the Doctor. The Brigadier insists that he is personally responsible for the Doctor. Chinn loses his temper and the Doctor walks in.

Jo is talking to an American man who has been sent to UNIT to track down and deal with the Master.

The Doctor and Chinn argue with regards to his identification. Jo walks in and introduces Bill Filer and his reason for being there. The Doctor insists that there is no point in discussing the Master. Chinn wants to know who the Master is but Filer says it is classified, much to the annoyance of Chinn. An alarm goes off and Yates informs the Brigadier of the UFO. It is now 500 miles away. The Brigadier, accompanied by Chinn, rush to the radar rooms. Chinn rushes off to ring the Ministry - much to the relief of the Brigadier. The Doctor has no idea what it is but notes that it has variable mass and appears to be heading for the South East coast.

A tramp picks through rubbish on the seashore.

Chinn tells the Brigadier that the Ministry wants UNIT to be linked up with the missile strike force. The Brigadier complies. Chinn says that they will destroy the UFO as soon as he gives the word. The Doctor questions the Brigadier about this policy. Corporal Bell informs the Brigadier of freak weather conditions such as snow and dense fog on the South East coast.

The tramp wades through rubbish in a snowy terrain

UNIT have scattered all aircraft to avoid the UFO. Chinn orders the missile strike. Yates reports they have lost contact with the UFO. The Doctor points out that the warheads need to be destroyed. Panicked, Chinn aborts the missiles and destroys them in midair.

The tramp cycles across the snowy landscape.

UNIT still have no trace of the UFO. The Doctor points out that it has probably landed.

The tramp is disoriented by a bright light and cycles into a river. When he comes out he notices he is by the Nucton Power Complex.

Chinn is worried that this hostile force is threatening the power supply. The Brigadier sends all UNIT forces to the scene. Chinn places himself in charge. Filer asks where he should go. Chinn says that if he doesn't leave he will have him arrested. The Brigadier sticks up for him but Chinn leaves.

The tramp finds the UFO and explores it. A hatch opens. A tendril comes out and pulls him in.

Filer is in his car listening to the radio to find out where the UFO landed.

Inside the UFO, the tramp is being analysed. They register his locomotor facility as normal, his sensory receptors as acute but his intelligence as atypical.

Filer finds the tramp's bike and follows it to the UFO.

The tramp is valueless and the disembodied voice says he is to be absorbed, processed and ejected.

Filer examines the UFO. He sees the UNIT forces approaching. The tendril grabs him and pulls him in. UNIT sets up camp around the UFO.

Filer is analysed inside the UFO.

The Brigadier is introduced to Sir George Hardiman, who runs the Nucton Power Complex, and Winser, his head of research. Winser dissuades the Brigadier from attacking so close to the complex. Sir George agrees. Chinn says he has called for the artillery. The Doctor mocks his hardheaded viewpoint. The Doctor thinks a majority of the UFO is buried underground. The UNIT scientists pick up something that sounds like a heartbeat.

Filer is classified as intelligent, aggressive and possibly dangerous. He is to be held for further investigation.

The craft beams a message to the UNIT ship saying that they are from Axos and that their fuel systems have been exhausted. They request immediate assistance. The Doctor tells Chinn that this does not sound like his hostile force. Chinn still wants to attack. The Doctor says they should go and explore. Winser agrees. Jo is to stay behind with Yates as the rest of them explore the craft. As the men approach the craft the hatch opens. They all go in and the hatch closes behind them.

Benton reports to Yates that he has found a body. They rush off to investigate. They find the body of the tramp. It glows; pure white and iridescent.

Whilst the soldiers are distracted, Jo sneaks out.

The Doctor and his party explore the craft. Unbeknownst to them they are being watched. A high pitched trilling noise begins.

Jo approaches the craft. The hatch opens.

The Doctor is analysed. He is classified as non-typical and extraterrestrial and is to be investigated. The Doctor, crippled by the examination, calls for help.

Jo enters the craft.

The Doctor is released from the analysis. They continue to investigate.

Filer awakens. He is trapped under the weight of tendrils. He calls for help. He looks up to see that the Master is trapped alongside him.

Jo hears the shouts of Filer.

The party comes across some golden figures who approach them calmly. They say they are from the outer rim of the galaxy. Their planet, Axos, was crippled by a solar flare. They explain that science on Axos has taken an organic path and that the craft they stand in was grown from a single cell - however their nutrient is exhausted. They wish to stay until their nutrition and energy cycle is fully replenished. In return they will give the people of Earth Axonite.

Jo looks for Filer.

The figures explain that Axonite is the source of their growth technology and has the ability to absorb, convert, transmit and programme all energy. The Doctor says if this is the case how come the radiation from the solar flares effected them. He is told it was too late. The figures go on to say that Axonite is the chameleon of elements and can copy and recreate substances. The Doctor asks if this is the case how they ran out of fuel. He gets no answer.

The Master introduces himself to Filer.

As a demonstration, the figures inject Axonite into a frog. It expands. They explain how it would alleviate food shortages. They reverse the frog back to normal size. Winser is blown away. Chinn says that mankind must have it.

As Jo continues to look for Filer a creature appears. She screams.

Episode two
The Doctor hears Jo scream and they all run off to see if she's ok except for Chinn who is more worried about the Axonite.

Jo has fainted. The Brigadier berates her for following them into the craft. She says she heard Filer and saw a creature. The Axonits say that she is close to the organic power cells and she must be hallucinating. Jo is convinced that is not the case.

Filer tries to use his gun to break out. The Mater points out a ganglion on the wall that is the nerve centre. If it is hit it will disorientate that section of the ship for a while. Filer hits it and they are freed.

Chinn orders everyone out of UNIT's mobile HQ and contacts the Ministry. The Minister clearly dislikes Chinn.

Sir George and the Doctor discuss Axonite. The Doctor says he wants to experiment on it in their labs.

Chinn is told to sort the issue or get the sack.

The Master is recaptured. He argues that he has upheld his end of the bargain. Filer is lead away to the Replication Sector.

Chinn agrees with the aliens that the Axonite is to be controlled by Britain. They agree as long as it has worldwide distribution. They hand over a sample. When Chinn presents the Axonite to the Brigadier he demands that he hand it over. Chinn refuses until the Brigadier pulls his gun on him. The Brigadier leads them all out of the craft into the mobile HQ. They are faced with the army. Chinn explains that the army has taken over and that all of UNIT are under arrest. Chinn gets the Axonite back and the Brigadier is out under twenty four hour armed guard.

Filer is going through some sort of process in the craft.

The Doctor is wondering what is going on. He tries to think about what the link is between the creature and Filer in the craft.

The process continues.

Jo explains to the Doctor about the tramp and the fact that his body has now disintegrate. The Doctor speculates about Filer. Jo refuses to consider that he might be dead. She says they should search the craft. Chinn, who has been eavesdropping on this, blocks it.

Filer is duplicated.

Jo argues with Chinn but he still blocks it. Jo is arrested and the Doctor is confined to the lab under the protection of Winser.

The Axonites are in cahoots with the Master. He led them to Earth in return for the destruction of the Doctor and all life on Earth. An Axonite says that in order to get maximum nutrient value from the Earth, Axonite must circle the world in seventy two hours. The Master says he can help with this. The Axonites have lost trust in the Master as he did not tell them that the Doctor was also a Timelord. Filer is thrown into the room and collapses.

Winser is showing the Doctor around his lab. He shows him a Light Accelerator that he thinks might be the first step towards time travel. The Doctor says he has already cracked this.

The Axonite controller tells the replicated Filer to find the Doctor and bring him to the craft.

Winser is in disbelief. The Doctor offers to show him his TARDIS. He believes the Axonite might fix his ship.

Filer awakens. He is trapped but manages to free himself.

Winser is horrified that the Doctor thinks they should use the expensive Light Accelerator to analyse the Axonite. Winser intends to do it the old fashioned way.

Filer escapes from where he is being held.

The Master pleads his case for being allowed to help the Axonite cause. They analyse him as having the ability but are concerned about his motivation. They decide that he can help but they will retain his TARDIS. Filer overhears all this. As the Master is freed, an alarm goes off alerting the Axonites to the escape of Filer.

The Master sneaks out of the craft. A UNIT soldier sees him and the Master kills him. Filer sneaks out of the craft unseen.

Winser is unable to analyse the Axonite. The Doctor says it is revisiting analysis and that particle acceleration is the only answer. He offers his TARDIS for this process.

The Master jumps atop a UNIT lorry and hypnotises the driver.

The replicated Filer enters the lab and grabs the Doctor. He is resistant to Venusian Karate. He knocks the Doctor out. The real Filer enters and tries to shoot his doppelgänger but he is resistant. The two fight. Eventually the replicated Filer is forced into the Light Accelerator and disintegrates.

The Master orders the driver to load the Doctor's TARDIS into the lorry.

The Doctor tells the Brigadier about the replicated Filer. Filer tells off the fact that the Master is involved and that he has said that the Axonite are scavengers and that there is no Axos. The army burst in and say that they have been bugging their conversation. The Doctor is now to be confined to the lab.

The Master sneaks in to the radio room and tells a soldier to send a message to the UN.

Confined to the lab, the Doctor decides to use the Light Accelerator. He records the process. As he begins the Axonite starts to smoke.

Inside the craft the creatures are effected. The Nutrition Cycle has begun prematurely.

Filer knocks out the guards that are keeping watch if them and frees himself, the Brigadier and Jo. Jo and Filer go to look for the Doctor. They find the Doctor in distress. The Axonite is absorbing the reactor to fuel it's growth. Winser bursts in, furious for the Doctor using his equipment. He tries to open the Light Accelerator and is electrocuted. His body immediately disintegrates. The Doctor realises that everything is made of the same element; the creatures, the craft and the Axonite. He also realises that he has activated it. They are soon surrounded by membranous creatures formed by the Axonite who start to pursue him.

Episode three
Filer is shot by a tendril from one of the Axonites. They reenergise and re-personalise into the golden figures. They hypnotise the Doctor and Jo and take them back to the craft.

The Brigadier is trying to get a message to the UN but is confused when he is told a similar message has already been sent out. The army guard enters and tells him to hang up the phone but the Brigadier says he should check his orders.

Sir George and Chinn run into the lab. An Axonite tells them that Winser was killed by radiation and that it came to help but it was too late. It says that if anymore unsanctioned experiments take place they will withdraw their offer.

Jo and the Doctor are held by the tendrils in the ship.

The army captain tries to tell Chinn something but he won't listen. The Axonite says they don't know where the Doctor and Jo are. They find Filer in a coma and take him to the medical wing.

The Axons explain that the Axonite was a bait for human greed. Their plan was for it to spread across the planet and then they can begin their nutrition cycle; consuming every particle of Earth's energy and sucking the planet dry.

The Ministry have put the Brigadier back in charge. He sends out UNIT forces to find the Doctor and Jo.

The creatures tell the Doctor they have 72 hours to reenergise. The Doctor thanks Chinn for trying to keep in Britain.

The Ministry contacts Chinn and says that the UN know of the Axonite and want it deployed around the world. Chinn is order to do this immediately or be sacked. He organises the air transport.

Filer is in hospital muttering about Axonite, danger and distribution.

The TARDIS arrives at the Nutton Power Complex alongside a figure from the army who tells Yates he is here for a surprise inspection. When left alone, it is revealed to be the Master in disguise. He heads straight for the lab and enters the TARDIS.

Filer mutters about help and finding the Master.

The Master looks at the butchered TARDIS console.

The Doctor is tortured. The Axonites want the secret of time travel to expand their field range. He insists he is not a Timelord.

The Master thinks he might get the TARDIS working again.

The Doctor refuses to help. He is tortured again. The Axonites age Jo in front of his eyes. He begs them to stop. He says that he cannot defy the laws of time but he will show them. They reverse the ageing process.

The Brigadier wants distribution to stop until they find the Doctor. The Axonites refuse and order to see the state of the distribution.

The Doctor telepathically passes on the equation for time travel and the power requirements. They confirm the data and the Doctor tells them they won't have enough power to facilitate it. The Axonites tell him to add in the power from Nutton Power Complex. He realises that will be enough but says they can't just walk in. They disagree.

Chinn tells the Axonite that Axonite is on its way to every major capital city and scientific institution in the world. The Axonite receives orders to depersonalise, locate and enter the main reactor and establish a link to transmit power. It walk out on a confused Chinn.

Filer tells the Brigadier what actually happened. The Brigadier goes to tell Chinn. He is followed by Filer.

The Brigadier sees the Axonite mid-transformation and pursues it. He sees the Axonite attack and kill three UNIT soldiers on its way reactor. It enters the main furnace.

The Brigadier returns and tells Sir George to check the main reactor. The readings are up.

The Master is thwarted in his attempts to get the TARDIS working. There is no power and no stabiliser. He manages to get the scanner working, which gives him an idea.

Sir George says that if the Axonite walked into the reactor it must be dead. They see the Master in the lab. He enters the Light Accelerator. The Brigadier sends for more men and they sneak up on him until he is surrounded. He tries to run but there is nowhere to go. He is disarmed and handcuffed. He says he wanted to steal the TARDIS to escape. Sir George says that the reactor is about to go critical. The Master explains what is happening and offers his services in exchange for freedom. The Brigadier refuses but Sir George stresses how dangerous an explosion it would be. The Brigadier complies. The Master's plan is to stack up power from the Light Accelerator into the TARDIS, channel it back into the Accelerator and boost the power that the Axonites are expecting back at them in one huge surge. Filer enters and pulls a gun on the Master. The Brigadier calls him off.

The Doctor watches as the power builds up and the Axonites prepare to enter the time field. Suddenly the power supply starts to drop. As the Axonites become disoriented the Doctor sneaks out. He is briefly caught by the tendrils but breaks free.

Sir George is having second thoughts about the Master's plan. The Master tells him he has to take the risk.

The Doctor frees Jo.

The Master is ready to pull the switch that will start the surge. Filer asks about the Doctor and Jo. The Master says that they will die. The Brigadier stops him. The Master says that either they destroy the Axonites or the Axonites destroy the world. The Brigadier walks away. The Master pulls the switch.

The craft rocks and shakes as the Doctor and Jo fall to the ground.

Episode four
Sir George reports that the Light Accelerator is registering well over maximum. The Master boosts the surge through the TARDIS.

The Doctor and Jo are chased by Axonites. As they run the floor starts to disintegrate. The Doctor says that they are suffering from electro-convulsions as their is an electrical storm in the ship's brain. Jo starts to freak out but the Doctor focuses her brain using maths. They manage to escape.

The Master thinks he has solved everything and goes to leave in the TARDIS. The Brigadier stops him. The Axonites have reversed the power flow and are feeding it all back into the Light Accelerator.

The Axonites are trying to set about destroying the Light Accelerator.

Sir George evacuates the Accelerator sector and tells the Brigadier that he intends on disconnecting the cables alone. The rest watch in as he attempts to do it. He removes the wires but in the last minute is thrown across the room due to a huge power surge. In the confusion, the Master tries to escape but is stopped by the Doctor.

The Doctor tells them that the Nutrition Cycle is still ready to begin. Once it has started Axos will grow until everything is consumed. The Doctor wants to use the lab's computers for some calculations. The Brigadier is going to keep a watch on the craft. The Doctor wants the Master's help and says he will use his weapon on him if needs be.

The Brigadier sets up a perimeter around the craft. Yates places a camera for the Brigadier to observe. Chinn enters and wants to get in touch with the Ministry. The Brigadier blocks him and tells him that Sir George is dead.

Filer is concerned that the Master and the Doctor are plotting. He is suspicious as to why they have insisted that they work alone.

Inside the TARDIS, the Doctor confides in the Master that there is no plan. He says that the Master should mend the TARDIS and that they should both escape and leave earth to Axos. The Doctor says that if he doesn't help he will hand him over to UNIT and they will all die together. The Master asks why the Doctor cannot escape himself and the Doctor admits that the Timelords have put a block on his knowledge of dematerialisation theory. The Master agrees. He says he can use the trigger from the Light Accelerator to compensate for the deficiencies in the Doctor's dematerialisation circuit. The Doctor leaves the Master to fix the TARDIS while he goes to calculate a course. He takes a part of the circuit to act as insurance. The Axonites activate their Nutrition Cycles.

The ship rises up out of the Earth. Yates is withdrawn. The Axonites try and stop his withdrawal. He drives through some of them and then is forced off the road. Finally he is blocked by a felled tree. The Axonites ambush the lorry. The UNIT forces manage to knock one of them off but then use a grenade to destroy the vehicle with the Axonites clinging on to it.

The Doctor says he has finished his course calculations. Filer asks where he is going. The Doctor confirms he is abandoning them. Filer pulls out a gun but the Doctor disarms him with the Master's gun. Everyone else enters and the Doctor bids them farewell and enters the TARDIS. Jo begs for the Doctor to come out as it begins to dematerialise. UNIT Forces enter and take refuge from the Axonite onslaught.

The Doctor starts the rematerilisation process before the TARDIS has been entered space time. He orders the Master outside. They are back in the Axonite ship. The Doctor offers the Axonites an alliance. They will join forces against the Timelord High Council for the gift of time travel. The Doctor says he will fuse the TARDIS's drive circuits with the drive circuits of Axos and therefore fuse the two ships together. The Master wants to leave but there is a forcefield around his TARDIS.

The Axonites are gaining entrance to the lab. The UNIT soldiers are preparing their weapons. All of a sudden they stop. A bolt of electricity comes through the door which reenergises the Light Accelerator. It sets about overloading.

As the Doctor is fusing the TARDIS to Axos, the Master realises that he has put the TARDIS into a timeloop. At the same time all of the systems between Earth and Axos are disconnected and the Nutrition Cycle is incomplete. The Master rushes out and says that the Doctor is committing suicide and taking them all with him as once they enter the timeloop they will never get out.

The Axonites enter the lab and set about destroying the UNIT soldiers. All looks lost.

Outside the Axonite ship disappears.

Inside the lab, one by one, the Axonites disappear.

The Doctor is joined by the Axonites in the timeloop. He tries to break through and Free himself.

The Light Accelerator is still building. The Brigadier orders evacuation. The TARDIS rematerialises into an empty lab. The Doctor emerges and as soon as he does the lab starts to fall apart. He re enters his TARDIS.

The Brigadier, Jo and UNIT watch from a distance.

The TARDIS dematerialises.

The Power Complex explodes. The Brigadier, Jo and UNIT return to the wreckage. As they explore the TARDIS rematerialises.

The Doctor explains what he did to save the world. He struggles to explain the concept of a timeloop to the Brigadier. Filer asks after the Master. The Doctor hopes he is trapped in the timeloop too but cannot be certain. The Brigadier asks if he meant to return to Earth. He initially says he did but when pressed he says that the Timelords have rigged his TARDIS so that he will always return to Earth - like a galactic yo-yo.

Story notes

 * Working titles for this story included Doctor Who and the Gift, The Friendly Invasion, The Axons, and The Vampire from Space. The last title was used through the production of the first two episodes. It was changed only by the time filming began on the third as the BBC wanted to avoid the word "vampire". The DVD release contains unused footage and cuts from the story packaged with the original title sequence — naming the story as The Vampire from Space. The Vampire from Space was envisaged as a seven-parter, but the concept of the storylines changed as production progressed.
 * The line "freak weather conditions" is in the script to explain the shifts in weather between filming (which goes from snowy to sunny from take to take).
 * For reasons unexplained, the opening titles for this serial use the Second Doctor's version of the Doctor Who theme music as opposed to the Third Doctor's, as do The Mind of Evil and Terror of the Autons. After this serial, the theme reverts to the Jon Pertwee standard.
 * For the scene in episode three where Axos accelerates Jo's ageing process — as seen on a large video screen — in order to force the Doctor to co-operate, another actress, Mildred Brown, who was uncredited both on-screen and in Radio Times, was used for the shots of Jo as an old woman.
 * The Radio Times programme listing for episode one was accompanied by a black and white full-length photograph labelled "DOCTOR WHO in The Claws of Axos" showing the Doctor and Jo, with an inset of the pair escaping from Axos, with the accompanying caption "A new adventure for Dr. Who and Jo: 5.15".
 * Bernard Holley (Axon Man) also provided the Voice of Axos, but was uncredited on-screen.
 * Donald Hewlett (Hardiman) is credited as "Sir George Hardiman" in Radio Times.
 * Paul Grist is credited as "Filer" on-screen, and as "Bill Filer" in Radio Times.
 * Patricia Gordino (Axon Woman) is credited on-screen for episodes one and two, but not in Radio Times.
 * John Hicks (Axon Boy) and Debbie Lee London (Axon Girl) are credited on-screen for episode one, but not in Radio Times.
 * Michael Walker (1st Radar Operator) and David G. March (2nd Radar Operator) are credited collectively as "Radar Operators" in Radio Times for episode one.
 * UNIT's mobile HQ is portrayed by a BBC Outside Broadcast van, with the BBC logos obscured.
 * The original script called for the Axons to land in Hyde Park, with their ship shaped like a human skull. The script was spectacular in other respects also. The production team loved the story, but had it scaled down on account of impracticality and budget.
 * One of the Axon costumes was later adapted (in other words, repainted green) for the humanoid stage of the Krynoid in The Seeds of Doom.
 * Nicholas Briggs jokingly said on the David Tennant video diaries that if they didn't finish the ending of Rise of the Cybermen and the beginning of The Age of Steel, they would have to do a Claws of Axos rewrite.

 * Episode four - 7.8 million viewers

Myths

 * A common myth about this story is that the colour separation overlay (CSO) background was accidentally placed in some of the car interior scenes, meaning a blank blue void is seen behind the characters. In reality, the scenes were shot on location (and on 16mm film, making CSO extremely tricky), and clouds can be seen. The differing shades of blue compared to the exterior shots is due to the scenes being filmed at different parts of the day.

Filming locations

 * Dengemarsh Road, Lydd, Kent
 * Dungeness Road, Dungeness, Kent (Where Axos lands and half buries itself)
 * , Dungeness, Kent (Location for the Nuton Power Complex)
 * Dungeness Beach, Dungeness, Kent
 * St. Martin's Plains Camp, Shorncliffe, Kent
 * BBC Television Centre (Studio 7, 3 and 4), Shepherd's Bush, London

Production errors

 * In episode four, after the TARDIS dematerialises from the Nuton lab, it is still there during the UNIT gun battle which follows.
 * In episode two, during the "absorption" scene, the Axon Woman's mask fails to inflate due to the stuntwoman not fitting the size of the mask making it appear to deflate and the mouth was where the mask's nose was when the stunt double is breathing in. This is even commented on in the production notes.
 * In episode three, when Jo Grant is being aged, the eyes of Katy Manning and Mildred Brown do not match properly.
 * As the Brigadier and his men leave the room where they've been held captive in episode two, the wall shakes.
 * The Axon on the bonnet of the car explodes before the grenade that supposedly destroyed it.
 * When the Master kills the UNIT guard outside Axos, the guard's beret flies off. However, as the Master moves off, the beret is back on the guard's head.
 * The model shot of the TARDIS exterior in part four shows a St John Ambulance sticker, unlike the actual prop itself seen in this episode. It would seem that the production crew were using a model from the 1960s, when the TARDIS did bear the sticker. Although an obvious production error, it's interesting as one of the only colour examples of the St John's cross prior to its reintroduction in The Eleventh Hour.
 * The CSO has many notable errors, most obvious is the frog shown in episode one, which is missing many areas that should be there yet has a flickering shadow.

Continuity

 * This is the first that time the interior of the Doctor's TARDIS has been seen since TV: The War Games.
 * later mentioned their encounter with the Axons to the Tenth Doctor. As the Master lay dying and refusing to regenerate shortly afterwards, the Doctor asked him to remember all of their experiences, including their encounter with the Axons. (TV: Last of the Time Lords)
 * A Liverpudlian UNIT soldier named Francis Cleary was deeply disturbed by the sight of one of his fellow soldiers, a good friend, being killed by an Axon at the Nuton Power Complex. (PROSE: Who Killed Kennedy)
 * The cause of "freak weather conditions" is revealed in AUDIO : The Magician's Oath.
