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

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?
 * 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.
