Theory:Doctor Who television discontinuity and plot holes/The Eaters of Light


 * Why would Bill wonder off on her own to find a Roman soldier, that could easily kill her?
 * Well, the Doctor thought they were all dead and Bill has reckless bravery?
 * Aberdeen wasn't deserted. She could still have been in danger!
 * No Roman wanted to kill them. They were clearly not barbarians. And it doesn't seem the Doctor foresaw the Picts wanting to attack them, so he didn't see any reason to worry.
 * We didn't know at the time the Romans didn't want to kill. Only in hindsight!


 * Why has it taken so long for Bill to realise that the TARDIS can translate language?
 * Because her adventures never needed this information clarifying?
 * She just had an adventure with aliens from Mars? Wouldn't that raise a question?
 * She's clearly a bit thick. Or it simply didn't occur to her at the time. The scene was meant to be humorous. She even says, "Oh, that's why everyone in space speaks English," or something like that when she figures it out.
 * Although I can't understand your sentence, much fuss has been made that the TARDIS didn't translate in Extremis!
 * The simulated world the Monks created wasn't totally perfect. Some aspects of history were slightly off - some due to the very fact that the world was simulated itself, leading to some people figuring it out and thus the writing of the Veritas and thus the establishment of the forbidden library of heresies in the Vatican and, probably due to some kind of butterfly effect, its founder, a woman, becoming a pope - including the US president being wrong (the next episode, in the real world, indicates it is, in fact, Trump, but Extremis' actor looks nothing like him - wrong hair color and everything) and, evidently, their not knowing how the TARDIS works exactly, leading to their missing the telepathic translation property.


 * Who built the gate? How did it get there? Isn't the gate still there?
 * How is this a continuity error?
 * Plot hole!
 * How? Just because it didn't tell us doesn't make it a plot hole, not like it's a paradox or anything
 * Of course, its a plothole. Its because the viewer isn't told makes it a plothole!
 * No, we are actually told. The portal itself was a time rift. The cairn built around it and used as the gate was constructed by ancestors of the Pictish natives from the episode.


 * If the stones blocked the entrance of the gate, wouldn't removing the stones open it up again?
 * The stone from the building started to crumble!
 * That's because too many people travelled through the portal at once
 * Well, thats not what I asked. Obviously, the portal is now blocked. But, removing the stones would re-open it, surely? It is still there! In Aberdeen!
 * Unless it got buried under the hill, too, which actually seems to be the case based on some comments made by the Doctor and Missy, and the view of what remains from the modern day portions.

 * I couldn't understand how or why the light was damaging the monster before it was pushed back into the gate!
 * It's the reflectors they used, it destroys the light in a way that harms the creator rather than empower it
 * I think it might have actually been acting like a lure for it, baiting the beast into the rift, and the boy - who was both primitive and young - simply did not fully understand how it worked when he explained what the glass substance did to the Doctor. Because it seemed to me that glass substance MAGNIFIED the light, which would be attractive to the beast, I would imagine, not damaging.


 * Why is there an engraving of the TARDIS on one of the rocks, when none of the survivors saw the Police box?
 * Maybe they did, the Doctor was in the gate for two days at one point so that was ample time for them to find the TARDIS and probably for Nardole to class it as off limits.
 * It might have even been visible to them as the Doctor and his companions left and went into it far off in that field - that field might have been a relatively straight shot from wherever they left the Picts.
