General Impressions: I still think they were playing around with the idea of Paul and Adelle. Because we see in this episode, how Adelle's initial "such a tool" reaction gets replaced by a certain respect, admiration. This carries over to Belle Chose, where we can see Adelle watching Paul in action with an admiring smile. And then in "A Love Supreme", Adelle seems to have a somewhat jealous reaction over the Echo/Paul romance revelation. I mean, remember the EvilGlare!Adelle in the end of that episode! And since the next episode started immediately with Adelle in sack with Victor, which kinda implied that she was trying to hump out whatever infatuation she had for Paul, but Victor rejects her and thus makes her unloved woman twice in a row, and she's all double unloved and starts drinking heavily, and that episode actually ends on a certain note that she's sending Echo to the Attic because of jealousy. Of course, it's all part of the big plan in the next episode... but the point I'm trying to make is that, in my opinion, they were playing around with the idea of Paul and Adelle (and making it potentially very complicated quadrangle) and this episode drops the first hint of this with Adelle's first admiring smile, which then gets repeated in Belle Chose and... I'm a bit unfocused. Sorry. It's just I've got all these recent events running around in my head... probably the whole thing needs to be redone.
Also Topher is just so hurt when Whiskey says that she hates her. That Whiskey is one fucked up individual.
Echo's Journey to Enlightment: We already discussed the Briar Rose allusion in the previous episode. All we can say is this. Echo get's a treatment that should fix her back into a normal doll, she walks, notices that Topher is sad and then comforts him... and cue meaningful song. Echo's a real person now.
The Question of Boyd (did they pull it out from their asses or not?): "There's always a girl." - Boyd's comment when Paul says that he isn't working for Dollhouse, but looking after Echo. Fits perfectly with the new revelations.
Foreshadowing: "Call me Omega again and I'll..." She has finally finished her Echo identity. This shows how she identifies from now on as Echo, that she won't let others tell her who she is, and not as Omega or Caroline.
