Theory:Torchwood television discontinuity and plot holes/The Blood Line


 * It was stated on many occasions by Jack that his blood was unbale to transfer his immortality but why was Rex Matheson able to heal after being shot?
 * His blood didn't transfer his immortality—otherwise, Rex would have been healed before they got to the Blessing, and removing his bandage would have had no effect. It was the Blessing that transfered his immortality. It's not made clear how this works, of course, but all the technobabble about the Blessing was about it locking onto blood, configuring itself based on blood, etc. So, the Blessing recognized Rex as Jack, or a member of Jack's otherwise-unique species, or whatever, and applied the immortal morphic field to him accordingly.


 * This is a trivial one, and it's probably more of a production error than a discontinuity, but: The CIA has 703 area codes, and always has (unlike most other government agencies in the area, which still have 202 area codes even if they're outside the District). And many CIA employees choose 703 cell phones instead of 202 (or 301) no matter where they live, as a sort of "Company pride" thing—when your phone rings with 202, it's probably that DIA liason you're working with or that Congressional committee flak who keeps bugging you, not a fellow agent who actually matters. So, when that first "2" popped up on the screen, it would have narrowed down the suspects consdierably, and someone probably would have commented on it.
 * Perhaps, it may have narrowed down the suspects, but why do anything when you'll find out exactly who the mole is in a matter of seconds?
 * Maybe I was misled by the "tension music" in the soundtrack, but it seemed like they were pretty impatient waiting.
