Theory:Doctor Who television discontinuity and plot holes/The Curse of the Black Spot


 * Wouldn't the TARDIS translation circuit make Captain Avery understand what the Doctor meant by "sensors"?
 * If he doesn't know what they are, he still wouldn't understand what the Doctor meant. It's like how the people in Pompeii didn' t know what a volcano was.


 * If the crew on the alien spacecraft got a human disease then why didn't the 'Siren' put them in stasis as well instead of leaving them to die? Toby had a fever and he was put under stasis. Shouldn't the same apply?


 * Why would a spaceship have a virtual Doctor that can't actually cure people?


 * When Doctor and Co got zapped into the alien ship, they arrived merely briefly stunned. All other victims were stored in suspended state upon arrival, even those who had no life-threatening injury. Why the different treatment?
 * We didn't see their arrival. Presumably they arrived merely stunned, but the Siren overpowered them and got them into stasis. The same would have happened to the Doctor and friends, but he did his usual fast talking followed by fast action.
 * Also, the Siren had just been freed from a barrel and had to chase after a whole group of people, so she may not have been as prepared as when she picked up the others one by one at her leisure.


 * Even for Dr Who, it's a bit of a stretch to have a crew of sailers with no knowledge of science more advanced than the astrolabe able, with no training, to successfully pilot an alien spacecraft that doesn't even have controls labeled in a langauge they could understand.
 * It's possible that they took weeks to learn to fly the ship, which we didn't see. That would also explain why the boy was healthy at the end, even though the Siren couldn't directly cure him (and it would take a few days to recover even if she could). And why they seemed to be heading toward a clear destination, rather than just "away from Earth".
 * I dont think he was cured, possibly still on life support as he still had the pipe going into his throat and that transparent choker. The other crew however didnt have injuries more than a few scratches which should heal on their own. The Aliens spacesuit had latin letters on it so possibly some of the ships systems could have been in an understandable alphabet.

 * A repeat of the classic 'Period Terminal Illness' hole: The Doctor could cure anyone if he wanted by just taking them on a day-trip to a period when medicine has advanced sufficiently. Collect boy, go forward a few centuries, collect antibiotics, return boy. If this is against the Doctor's non-interference rules or risks the integrity of the timey-wimey ball, then so be it - but it would be nice to see the possibility at least mentioned and dismissed rather than leave it dangling.
 * The Doctor had an obvious ulterior motive here. He knew that, given the circumstances, Avery was going to choose to stay with his son and fly the spaceship off together and live happily ever after. If he healed the boy and returned him, or just told Avery of the possibility, who knows what Avery would do?
 * Also, the Doctor didn't need to cure the boy. With typhoid fever, if you make it through the month, you're pretty much guaranteed to survive. On a pirate ship, that might not be easy to do--but in a clean environment, with plenty of hydration and rest, the survival rate is around 80%, even without antibiotics. In a perfectly sterile environment with an emergency medical hologram zapping all the germs, it's probably even higher. And, if he happened to get unlucky, the Siren could put him in stasis for a couple weeks.


 * When the Doctor and Avery were running out of the TARDIS, Avery opened the door first. Since Avery was from the 17th century, how did he know how to open a door mechanism that hadn't been invented for another 300-400 years? The handle on a door is designed to be intuitive.


 * What reason did the Doctor have for his "let the Siren take us" plan? It was easy to dismiss the apparent "hail mary" play at the end of Amy's Choice--he knew the whole thing was the dream, he trusted Amy, he couldn't bear to contradict Amy, at the very worst it was a 50/50 chance. But this one just seems like "out of ideas, maybe this will work, otherwise we all die".
 * Isn't interdimensional travel supposed to be impossible since the end of Gallifrey, as 10 said back in series 2?
 * Maybe the spacetime reboot changed the rules.
 * There are many different kinds of parallel universe, both in real-life physics and in the history of Doctor Who. Maybe one kind is closed off, but another kind isn't.
 * Martha in the Mirror already had interdimensional travel (and through reflections, even) in the middle of series 3, so maybe the Doctor was just wrong, or at least not very precise.
 * In short, "Nature finds a way". The very fact that the rift to the Cybermen could have happened at all shows that the laws set in place by the Time Lords were not hard and fast, especially since there were none to enforce it. These rifts are accidental, freak occurrences, like a CVE.

 * Is there any reason the ship has been totally becalmed for 8 days? It doesn't seem like it has any connection to the siren or the alien spaceship, and no other explanation is given.
 * Must have been connected to the ship being stuck in it, the same way the Tardis was becalmed as it couldnt sense the dimensional plane.


 * The pirate whose hand Toby cuts when they're in the magazine with Amy and Rory is discouraged from participating in his fellow pirate's mutiny when his blood is drawn. After the other pirate leaves with pistols in hand, he begins barricading the door again. This is the last we see of him. The scene cuts out, and when we're back in the magazine, it's just Amy, Rory and Toby. The pirate has completely disappeared and is never mentioned again. Made particularly jarring by the actor's subsequent appearances on Confidential . ..


 * I noticed that too.
 * He appears at the end with the rest of them on the alien ship so presumably he was caught offscreen.
 * Perhapes but still that type of stuff usually happens on screen. I didn't even notice him on the ship first time I saw that scene.

 * The CPR preformed on Rory shouldn't of been able to revive him even if Amy had preformed it properly.


 * I'll admit the CPR wasn't preformed properly because Amy didn't hold Rory's nose during the breaths. However, CPR on a electrocution victum or someone who is drowning can bring them back to life. I'm not making this up as my Dad his brought people back from drowning using CPR.
