"It's not--y'know, it's not that clear cut." Toriel is objectively a beautiful monster, heck -- she's a boss monster. Even more than that, she was smart, funny, tough as nails, funny, and could kick his ass if she really wanted to. Not to mention funny. Sans never was one to feel attraction one way or the other, but as far as companions went, he would be hard pressed to do better than her. When it comes to leagues, she's at least several thousand leagues outside his.

That's the kind of wordplay Toriel would love, and Sans wants to share it with her. Instead, he fiddles with his finger bones.

"We're always gonna be friends, Tori, you know that. And it's not you, it's me."
