I would've checked eating emotions next. [Not on Papyrus, though, considering how few of them he's been having lately. But that's not the point right now. Sans shifts forward on the shelf a little but doesn't move to get off of it.] I can--sync up, I guess--with what you're feeling. I don't need to touch you or anything, I can just do that from here.

[There's probably an upper limit to how far away from someone Sans can get, but as established, Sans has been trying to ignore his emotion-related stuff.]
