Mika glanced at him and saw him smiling again, and she couldn't help but smile slightly at the sight. Then when she realised she was smiling, turned it into a smirk then stopped all together. Until of course she watched him rub his hand over his lips and make a remark to her drinking and the sheer volume she was kicking back.
It made her realise that she only intended to stay for one drink. ONE drink she previously said, and yet here she is still drinking and not making her way back to Ethan. "Huh...." she smirked, just rising her eyebrows in a 'whatever' kind of attitude. "Like that wouldn't be awkward- and it's not like I have a home as such to go." She replied to Dean. Sure she had begun crashing at Ethan's place, but it wasn't exactly HER home. It was somewhere a bit more comfortable than probably this motel.
"Could say the same to you though, if we're both drunk I can't see you carrying me anywhere far," She told him, and she then twigged that, that could now be seen as a challenge in Dean's eyes. This night is just getting interesting she suddenly thought.
