"Yeah, you too," Ford replied automatically, because see you soon was a fairly routine way to end a conversation and he at first assumed that was what it was in this context. After a second he wondered if perhaps in this case it had been a real question, and bit his lower lip as though to signal he was about to try the answer again. "Think so, yeah. I, uhm — I don't have any fieldwork on Tuesday, if you wanted to do lunch?" This was one level more substantial than just saying see you around the office, but still significantly less invested than making actual plans at actual events. Easing into it.
Set by Lady!
