The relic was talking to me. They all do that, I guess. [He knows they've promised other people other things to convince them to use their power. Still, it's hard to remember the warnings when it's right there in your head, especially when the relic is actually three combined into one.] Talkin' about stuff I could do with it. Things I could go back and fix. [All that time magic right there in his hands, which is actually terrifying now, for a lot of reasons.] So then I guess I just--I remembered a real good reason not to mess with that. [He laughs, a little hollowly, but then his smile gets a little more real.] And I heard you talkin' to me, and you're way more convincing than some dumb magic book.

[But he'd wanted to use it until he'd remembered and Papyrus had grabbed him.]
