[Oh good, Sans has a face to work with now. A face and a name, even. He feels a little more like the ground is less catastrophically tilted in Wash's favor this way.]

I figure you know this already, but the name's Sans. [Just to be polite, and also so he won't feel weird if Wash ends up using it at some point during the conversation. As far as memories--Sans is trying to dig anything at all up, but it's not working. He didn't really expect it to, at this point. He hopes if this guy were super bad news he forgot about that he might get some sort of feeling, at least, and he isn't getting anything like that. Plus, Sans is sure the guy pointed out his actual stuff, and that stuff included some magic items that were probably worth something.]

So you're one of those lucky ones who woke up and got everything back, huh? [Sans clearly doesn't recognize Wash. It's frustrating!] Guess I shouldn't be surprised it's takin' me a while; it's all empty space up here.

[Sans just sticks a hand in one of his eye sockets. The light goes out before he does so, incidentally, and he shows no signs of being in pain or anything. This is a dumb joke.]
