I wasn't talking about what happened, since that is apparent. I was talking about the HOW.

If, as you say, the destruction of the gate can only affect what will happen, it couldn't have sent the Dragons into their own time, since that happened a few hours in the past. But if it can affect the past too, then why only the time travelers? And why only sending them back, but with intact memories?

Due to this contradiction the anchor theory is the only one that makes sense to me, without having to use a paradox as a lame excuse.
