Doctor Who plot holes

[Twilight_guy]

No those aren't plotholes. Plotholes are how its specifically mention in one episode interacting with your past self is a bad thing that will destroy the universe (in fact there was an episode about it) and then later in a Christmas episode specifically making a point to have a character interact with his past self to solve a problem and having it mean nothing. The only reason no one bitches about that is probably because different doctors (wibby wobbly continuity... stuff).

Are you talking about "The Next Doctor"?

No. See below.

I think in the episode you are thinking of it's only if the subject goes back to their past rather than their past coming to the future. That and stuff went to hell when Rose changes HER timeline by saving her dad in comparison to the old bloke seeing his future self (I assume that's the special you're on about at least) where all they did was hug, theoretically impossible but the Doctor has crashed into himself before without too much happening so maybe it's only in special circumstances.

You say special circumstances I say plot hole. Of course in all good scifi they usually resolve plot holes by breaking physics or pulling stuff from their asses from I'm not upset or anything I just wanted to point out that this is closer to a plot hole, when something goes against its own in universe rules or continuity.

Which Christmas Special are you talking about then (I seem to have missed on and would like to know what to look for)

The one noted above.
