[Papyrus perks up at Lambert's last remark, sitting upright and eyesockets widening. He decides to answer that question first, just in case it tells Lambert something important.]

Hmmm. My brother said there was 'somebody else' before the human... But, of course, he didn't say who! Or why.

[Being dependent on Sans for information about all this stuff is incredibly frustrating. If Papyrus weren't striving so hard to be pleasant and kind, and his brother weren't in such visibly awful condition, well, he probably would've been on his case that much more.

Visibly awful from the first time they talked, back in the Dream world. To Papyrus' sight, anyway. One of the benefits of being skeletons in worlds with very few skeleton monsters is that they have pretty decent poker faces. Sure, Papyrus emotes all the time, but they're almost comically exaggerated expressions. The tiny hints of feelings that come with small muscle movements are lacking, with his lack of muscles. And Sans has a constant smile, for all that careful attention to his eyesockets reveals some things. It really helps them keep things secret, to pretend all is well.

Not to say that Papyrus' loud and silly demeanor is all pretend. He exaggerates some things (like his reactions to puns), offers encouragement faster than criticism, and generally tries to be enjoyable to be around... But his weirdness, and his tendency to be astonishing forthright with some of his feelings, is all him.]

So... How else could I look at this? Bring on the best and worst alike, I welcome all perspectives, no matter how repugnant.
