Martha realises that the Doctor hasn't noticed her awful attempts at flirting and isn't interested. The Doctor realises that while he lost everything, Skaro lived on. The Daleks realise that they are on the brink of extinction so go human. Impoverished New Yorkers realise that everything isn't right.
I loved this episode. The Daleks are absolutely fantastic - I particularly admire the idea of the Cult Of Skaro: the thinking Daleks. This ep., as all of the other Dalek ep.s, was just as good as the one that went before. I can't wait to see what happens next, with Sec the Dalek-human xD.
