[With Papyrus indecisive, Sans finds it difficult to maintain the levels of wariness necessary to resist sticking close to Papyrus. Anyway, he wasn't wrong that intangibility is his power; Sans is the one who knows how it works. Letting Papyrus go try to figure it out on his own would be dumb. Sans stands up, too.]

Well, I should probably keep helpin' out with your hand problem anyway. And I guess I should practice walking around with these eyes in the room. [Will he be able to see his room as clearly as he does now when he's in Papyrus's? That's going to be weird.] Unless you want a shortcut.

[Sans knows Papyrus would think a shortcut that short would be ridiculous, which is why he offered.]
