Dollhouse returned last night with a Whedon-written-&-directed episode called "Vows" which delved deeper into the moral ambiguities surrounding the Dollhouse (through Whiskey/Saunders' storyline) and set up the ongoing threads for season 2 (a senator-led witch-hunt against the Dollhouse, Paul & Echo's alliance, Whiskey's self-discovery). I don't know what new viewers thought (or if any tuned in) but it was a solid episode featuring a great cast:
Lee Adama (known as 'Jamie Bamber' outside the BSG-verse) played Echo's "assignment" - a husband whose business is a bit shady. (PS. Is Bamber hotter when he's angry/villainous or was that just me?)
Wesley Windham-Pryce (ie. 'Mr Alyson Hannigan' er... I mean 'Alexis Denisof' outside of the Buffyverse) plays (and will recur throughout) as a Senator who has it in for the 'Dollhouse': but why?
Amy Acker as Whiskey/Dr Saunders. After finding out her identity was a sham (she was the premier 'doll' until Alpha sliced her up) she's left in shambles battling with her inner-engineering.
Enver Gjokaj as 'Victor' (a doll) - following the same fate as Whiskey (at Alpha's knife) we find Victor getting cosmetic surgery at the Dollhouse's expense (which irks Whiskey, but then... we all know why Ms DeWitt would want to keep pretty-Victor's face intact, no?)
Dichen Lachman as 'Sierra' (a doll) has probably the most hysterical scene in the episode where her interaction with Ivy ("Uh, could I have the other one? The man one?") showcases her imprint's racist/sexual personality, but has little to do other than hold hands with Victor at the end of the episode.
Harry Lenix as Boyd Langton (Echo's former handler and now head of security of the Dollhouse) plays the 'father' figure throughout (not just with Echo but now taking on Whiskey as well).
Fran Kranz is Topher Brink, the mastermind behind the Dollhouse's technology - who we saw wounded and damaged in 'Epitah One' begins his morally-tinged journey into ambivalence with his interactions with Whiskey.
Olivia Williams (playing probably my favorite character on the show) is Adelle DeWitt, the head of the LA branch of the Dollhouse (yes! there are more we learned!) and is intent on keeping Ballard close at hand. Good thing she knows how to get things done: by emotionally manipulating people to her advantage.
'Helo' (Tamoh Pennikett) is (ex)Agent FBI Paull Ballard who after spending season 1 pursuing the 'Dollhouse' and finding out what happened to Caroline/Echo, is now 'employed' (though to what capacity the episode doesn't reveal til the end) under the Dollhouse though as DeWitt tells us, his motives (much too chivalrous) are his best guarantee in keeping Echo safe.
And last (and most would also say least) we have Eliza Dushku (Faith herself!) as 'Echo/Caroline): the 'best' doll in the Dollhouse who's self-awareness keeps chipping away at her doll-persona ("I am all of them, but none of them is me" she tells Paul at the end of the episode)
