Of course, Sans still finds coming back to this house strange, too, but the complete lack of recognition is a different kind of uncertainty.

"Yeah, it ain't much to look at, but it's home, I guess," Sans says, letting that 'I guess' do far more than its fair share of heavy lifting. He fishes the keys out of his hoodie pocket, a motion familiar to him from years of wearing it, which is strangely comforting in Sweetwater.
