The Sycorax are quite terrifying

Such a good design, I'd like to see more of them.

I actually rooted for Harriet all the way up to her call with Torchwood.

It's a really great portrayal, and TBH I think the episode does a decent job of laying out her motivations, right down to her rather weak apology at the end.

Maybe it’s just the third that’s on the roof at the moment.

I believe so.

I'm really not a Doctor/Rose shipper, but I am a big fan of the Tenth Doctor as a swashbuckling romantic, so I'm here for the flirting. I just never had any investment in things going beyond that.

I know this is more relevant to the upcoming Queen Victoria episode, but I think the themes of a Doctor and (especially) companion getting carried away with things were more aptly explored with Twelve and Clara.
