"You look Time Lord."

I'm still in the "It's new Doctor Who and I love it because it is" phase, but even still, I think I'll enjoy this one on the rewatch later. Erica is a lovely and competent character, and I'm hoping she sticks around for next week's denouement.

I think it's difficult for me to judge the strength or weakness of this episode overall until I see the resolution. We've had the opening, we've had the middle. If the final act pays off, this episode will be stronger. If it doesn't, then it's not going to be remembered as fondly.

Bill's reaction at the end seems in keeping with what I'd expect of a companion lately - sacrifice whatever it takes to save the Doctor, then trust that he'll fix the problem. I can imagine Rose or Amy doing the same in the end.
