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

Deleted statement
The following was posted at some point to the Discontinuity Page. I have deleted it from there as inappropriate as the discontinuity is not to be used for discussion of personal opinion (beyond explaining or rebutting errors that have been noted). However out of respect for the user to posted it initially, I have moved it here. As it was not signed I don't know who originally posted it. 23skidoo ☎  01:03, February 5, 2017 (UTC)
 * 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).
