Honestly he's just glad it's easy to spot him. The sooner he could get misunderstanding cleared up the better. He didn't know why, but the notion that he and Sans were in any kind of relationship together made him extremely uncomfortable. Needless to say he wanted to stop this rumor before it got a chance to thread. He nods his head in acknowledgement and greeting, before motioning to a table nearby. He doesn't feel he has to say anything to Papyrus to suggest they take a seat. He sits down himself, sighing, because though in theory this was an easy thing to explain, he'd already learned that Papyrus had a habit of complicating things.

"Yeah. Thanks for coming."

Where to start...

"Sans and I aren't in that kind of a relationship."

Well, that was as good a place as any... Maybe.
