Theory:Torchwood television discontinuity and plot holes/Immortal Sins


 * How does Jack know that he is a fixed point in space and time. In Jack's personal timeline, Utopia was still a long way away, and he didn't find out until that episode.
 * Do we actually know for sure that the flashbacks take place for Jack between Parting of the Ways and Everything Changes? It seems like he thinks his vortex manipulator is functional, he's well over 700 years old, he's wearing his WWII jacket, etc.—maybe none of these are discontinuities, and they all imply that this is Jack post-Children of Earth?


 * Jack says that he hasn't been to a confession in 700 years. Jack wasn't nearly that old until he was buried.
 * It's possible he was simply joking.


 * Where did Jack get a World War II coat? He didn't have one with him in Parting of the Ways, so it is unlikely that he would be able to obtain one until WWII.
 * He could have had it specially made.
