Theory:Doctor Who television discontinuity and plot holes/The Girl Who Died


 * I know that the Twelfth Doctor is more spacy than previous incarnations. I know that the Doctor sometimes wants to challenge the Laws of Time. I know that in this episode he is emotional, and when he's emotional, he makes mistakes. But... deliberately making someone immortal... that's just too much, even for him! If he remembers his adventures as the Tenth Doctor, I can't believe he doesn't remember about Jack and all the problems related to immortality (Jack was such an aberration that the TARDIS tried to shake him off to the end of time!). Jack becoming immortal was an accident, but this time the Doctor does it on purpose! (Ok, probably Ashildr has some important "historical" role to play in subsequent episodes - I haven't seen them yet, so no spoilers please - and the Doctor knows it vaguely via some wibbly-wobbly Gally-sense, but bestowing such a bless-curse on her still seems too much).
 * If the Mire are strong warriors and have a device that "repairs" them continuosly, it's unlikely that they are firghtened by a bad CGI monster (and when they see that the monster is not affected by their weapons, it's unlikey that they don't recognize their own hologram technology). Indeed, it's strange that the Mire don't rule the universe yet - or at least the galaxy - with immortality devices so cheap that every soldier has one in their helmets! (Ok, ok, we know for sure that at least two soldiers have them in the helmet, we don't know about other soldiers). The same thing could be said for the Chula, which we never see on screen, warriors that have nanogenes that cure everything and bring the dead back to life!
 * Ashildr mentions corn, which only existed in the Americas at the time and wasn't imported to Europe until after the discovery of the new world.
 * Electric Eels are native only to the Amazon
 * Both are correct but we don't take the real world into account here: http://tardis.wikia.com/wiki/Tardis:Valid_sources#The_real_world_doesn.27t_count
