I think this episode was an interesting one. I liked how different from the others it was, how it was all set in the Dollhouse and stuff. Knowing more about Mellie and Sierra, I feel really sorry for them, it's so sad, both of them. I would have liked to get to see more of Victors past, but him with Sierra is just too cute for words.
I must say that I was glad that Dr. Saunders didn't turn out to be all goody-good-good this episode. I mean, how in the beginning it looked like she was helping them escape, while in fact she was helping them to get 'closure', which, in a way, is of course as big a help for them since I doubt they would manage to survive outside the Dollhouse (You know, they don't exist any more, right?) I hate to say it, but I really can't stand her. However, in this episode, I liked her more than usual.
Freaked out Topher was fun, I liked the fight with Echo and the handler lady.
Finally, when are we going to see some more of Alpha? It seems like he's hiding or something. In the beginning there was a lot of suggestion but now he's sort of, not there anymore. Which is a shame, I'd say. I want to know more about him and his relation to Echo.
Also, I don't think that we're now back to square one. True, it was really heart breaking that Victor didn't even notice Sierra in the end (I was, in fact, looking out for that to happen, but it didn't and it was sad), but Echo's process of getting more self aware has been going on for a long time, or at least it's suggested, I am not too sure all of that can be wiped in one go. We'll have to wait and see. Either way, next episode promises to be a good one.
