Sans wobbles a little, but not as much as he really expected. Papyrus is heavy like this, but it's manageable as long as Papyrus doesn't forget to support at least some of his own weight. As far as the couch--Sans can't, for a moment, remember what color it is at all. He thinks of their green one instead, the one Papyrus obviously means, and wishes they were there.

But if Sans goes back, he'll be alone. So it's not worth continuing to think about.

"Nah, it's beige-y brown. Came with the house." Like all of the furniture, and also Sokka. Speaking of the kid: "But if we head back to my place maybe you'll run into Sokka."

It's been kind of funny seeing how long it takes for Papyrus to actually see the other person that lives in Sans's house, but now Sans wishes he'd been a little more proactive about arranging a meeting. Or active about it at all. This isn't an ideal meeting situation.

But he can't leave Papyrus alone. So he starts walking, seeing if Papyrus will be able to keep up without shaking out of his skin.
