Clara's stuff was fun and entertaining - her scenes with Smith particularly, I do love the ship teasing - but she did seem to slip into commading way easily. The kids were... well, I'm glad they were in a coma for most of it. The girl especially.
The Doctor's last line of the episode pretty much shows that they are going to continue with the shippy stuff. He's obviously attracted to her. It'll be funny going forward.
I actually don't think it's that at all. CyberDoctor wondered why the Doctor thought about Clara so much. The obvious conclusion is that he was attracted to her, but that's incorrect. Or, at least not the main reason. It's because she's the impossible girl.
I thought it was great that Clara knew that wasn't the Doctor because she knows he doesn't see her that way. Although, it was lame how the CyberDoctor was still able to destroy the detonator which she conveniently brought to him.
