[There's part of Sans that's gotten a bit used to talking to Papyrus without hiding things, while deliberately trying to remember things. But he has years of memories now that remind him that they don't really talk about things like this, or like--a lot of things. There's definitely part of him that wants to throw out some excuse and teleport away. But there are things other people know now, because the magic in the relics had dragged it out of him, so maybe it's not fair to keep hiding it from Papyrus. And, well, it had been... Nice? Bouncing ideas off of Papyrus.]

When I was hangin' onto the relic in the cave, I remembered something I forgot. [Of course, when it comes to this subject, even if Sans hadn't had his own conflicts with honesty, figuring out the words to use is difficult.] Not 'cause of stuff here. I forgot it--years ago, I guess.
