Maybe the Doctor wasn't as immune to the Daleks' nanocloud as we thought? Might explain his more aggressive behaviour since, and the lightbulbs shorting.
Thinking about it...yeah, I mean, did they ever address him giving Amy his watch in Asylum? That's a weird thread to leave dangling.
Also I find it really interesting how I like these episodes better then the past couple seasons and lots of other people think the exact opposite. I feel like a cosine wave.
