Yeah, I was gonna say the wisest tactical move would be to flank her to snipe and harass until we can either ambush her close enough for the oil or rustle up some backup - but again, with Alice being ruthless, she might have already gone to kidnap Renko for insurance instead.
Not the best plan :V
Actually, I'm not sure she'd have trapped the door - that doesn't seem like her style, and after Mary ran away odds are good Alice is confident that sheer strength will be enough to intimidate her without having to resort to traps (especially if she brings out Goliath to bolster that). Dolls will be watching it, certainly, but they'll be watching the front door, too.
