There's a beat before Colin looks back at him. Is Bene saying he wants to spend more time together? ...At night?

There are two things he does not want to do: get false hope, and end up locking himself in a closet again. Not that living in Lexie's flat has cured his numerous issues, but at least when he freaks out, he has an entire apartment and not just a closet.

"Well. I don't have to spend every night in the flat. Or go home as soon as I finish work."
