It's when Anthony is at the club, wandering around, before he fake sees Sierra.

He's at the bar and Adelle walks up to him and they start chatting. Because he's never seen her face before and she didn't sign him out when he left the Dollhouse, she's just a stranger to him.

He talks about how he feels like he's looking for someone and he's kind of drifting and hey why are you here this doesn't seem like your scene. And she's all 'I'm just checking up on a friend'. And he gets into how he 'just left the hospital' after being treated for PTSD and he doesn't feel like it really helped him. And she puts her hand on his and just looks at him like 'I'm so fucking sorry' and then he goes 'my hotel room is around the corner' at which point Adelle downs her drink, and tells him they both know she's not the girl he's looking for before leaving.

And then there's this wide shoe and it reveals Boyd watching them, which is pretty creepy.

I just would have been looking at her differently because her relationship to Victor was always a 'eh' to me. I never really saw it as a relationship with the doll/person and more he happened to be the meat suit worn with the personality of the lover she had made. So that moment would have changed that whole dynamic for me. Plus the Attic is right after this one, so that she would go out of her way to be a stranger to comfort him and then screw him and everyone over would have been interesting.

I'll take more caps and do a proper transcript.
