From this line: He thinks he owes it to her not to lead her on, so he makes it clear he’s not interested in romance. To her credit, Lisa agrees, revealing she only wants to go because she missed out on Ash’s party and wants a chance to let her hair down.

You took that as her wanting sex? We must read differently. I read that as her wanting to get drunk.

It's not even a pairing that's listed in the header, so there wouldn't even be a reason to hope for sexin' with those two. Even Dean/Bela was listed, and that really was about two sentences.
