Temporal Anchor I just don't see any concern with, since the spell is nothing but an absolute last resort if she's about to be killed or something. She can't actually pull herself out of it, so unless her allies go on to win the fight without her, she's just going to be at the whim of the villain once she comes out of it.<br/><br/>I can see your concern with the time travel spell, though. How about this: when she travels back, she loses all memory of things that happened after that point she traveled back to. So she's not only going back before any of the stuff happened, but she's also resetting to before she even knew it was going to happen. So every Flashback will actually have to be planned in advance so she doesn't just travel back and suddenly have no idea what she went back for.<br/><br/>That also creates the interesting drama of her not actually remembering anything that's told to her if she Flashbacks after it's been said.
