Theory:Torchwood television discontinuity and plot holes/Children of Earth: Day One


 * Wouldn't Tosh's Time Lock (DW: Journey's End) contain the explosion in the Hub?
 * No. When the Dalek exploded in Journey's End, it took out the time lock. Gwen remarked on it when it happened.


 * The time rift would be uncontrolled because of the destruction of the hub, however everything still seems to be unaffected.
 * The Hub was more often used to monitor the rift, not specifically to control it. Also, the Hub was, most likely, only created some time in the nineteenth century; hence, their rift is most likely not volatile enough to often cause major trouble in Cardiff within only six months, despite the destruction of the Hub.


 * When Lois looks up the history of Torchwood on the Government Information Network using Bridget's password, it says that Torchwood was established by "HRH Queen Victoria". It should have said "HM Queen Victoria".
 * Incorrect. Queen Victoria was the first monarch to be called "Her Imperial and Royal Majesty" which was still shortened to HRH and was not changed to HM until after her reign.


 * Why doesn't Jack just run out of the hub and allow the explosion to happen in the sea or in the open. This way the hub would be safe.
 * It was said by RTD in the 'Inside Look' for either this episode, or the next, that Torchwood Three was "too powerful" with the Hub, because of all the technology and resources they had, so "that was the first thing to go". Also, realistically, there simply wasn't enough time for him to get to the sea, and the government would have targeted the hub as well due to the vast technology.


 * Why doesn't any of the Torchwood Team use the Singularity Scalpel to remove the bomb from Jack.
 * It would have taken time to find the scalpel, which is a precision instrument easy to misfire anyway, and destroy the bomb, none of them have any practice of it. Alternatively, an attempt to destroy the bomb may have made it explode prematurely.


 * A running joke in the episode involves Ianto and Jack bantering about whether they're a couple or not. Hadn't this already been established during Series 2? ''(Ianto is clearly uncomfortable with the realisation that he is being viewed as part of an established gay couple. Of course he already knew it intellectually, but sometimes these things take awhile to sink in. People need time to adjust to big personal developments in their lives. They were never called an official couple in Series 2 despite their physical relationship no longer being kept private from the rest of the team. Ianto never told his family either.


 * When Ianto Jones is entering the LOCKDOWN Protocol into the computer a Error message is clearly seen on the screen near him showing that the Computer's Operating system is in fact Linux.
 * Is this really a plot hole/discontinuity/error, it is possible that Torchwood's operating system could be a form of Linux, with Tosh having edited it a lot.


 * When Ianto Jones enters the protocol for the lockdown, why isn't he locked in, as surely the lift would be locked?
 * There may have been a delay in total lockdown for the purpose of allowing personnel to escape.


 * When Lois comes out of the office that Colonel Oduya and John Frobisher are talking in, she asks Bridget what uniform the Colonel is wearing, saying that it is not British Army, but actually it is; the only difference is the UNIT logo on the left breast above his medal ribbons.
 * So it therefore isn't British Army.
 * But the British Army have lots of patches that can be used to embelish their uniforms depending on certain specialities; unless Lois is an expert at identifying British Military insignia, surely she wouldn't think that a small patch is anything out of the ordinary.
