"Hopefully not everything I want, just one of the things. I have enough suspicions about incest already, let alone my actual sister." He winked, drawing her closer with a warm arm across her shoulders. Folding his fingers over her hand with the bottle in it, he maneuvered them upward towards his mouth as if to drink from it but knew she'd struggle and ait before he could actually drink the stuff.
"Nothing's up, if it was I wouldn't be here but whiskey is what's going to be up, or rather down in my beer gut." With a little persuasion his arm draped over those feminine shoulders brought her forwards when he moved, leading them back along the sidewalk towards his apartment building. "What's up with you, Miss "I live in shelters now", hmm?" It was going to be odd having someone else stay over, he still hadn't decided if he was going to let her have the bed or not yet. That could wait until she was there and he'd tasted her offerings. Those being the whiskey, not some other pun.
As for Sev's state currently, he didn't particularly notice yet but assumed her half-drunk, steering her with him because he liked to be in control and she was still shorter than him, thank god. Ben might act silly, but at the end of the day he was 25 and had the full presence to agree with it in a casual way, at least compared to his younger sister.
