I've only seen the first episode of Sherlock S2, I need to finish the other two - but there's no rush since it won't be back forever, and I've had a lot of it spoiled for me already anyway lol.

I really like Sybil and Anna too. I didn't really like Mary at first, but she grew on me - I'll be curious to see how your opinion of her changes (or doesn't). I feel really bad for Edith, although she's done some stupid shit.
