Elastic. Yes, that's a great word. Hmm. But some overacting is obvious even on screen. "Chewing the scenery" has to come from somewhere.

That and a bit from the final Eleven episode, that one Christmas special. What I saw there? Left me even less impressed. Her whole arc is proof of why SOME continuity is critical even in a show that's sometimes all about re-telling or changing things, and where logic is difficult to come by. I don't blame you.
