Cole just brightens up as he hears Papyrus, demeanor shifting from his more closed off sort of quiet normal Cole self to something a bit more bright and open. He hadn't been paying attention to who he was talking to but good! It's him! He likes Papyrus, most people don't think as bright as he does.

Papyrus thinks that Cole's talking about the dragon, Cole's perfectly happy to roll with that, even though he doesn't think he was talking about the dragon in the first place.

"I've seen dragons before. This doesn't feel like them," Cole explains, as if it's perfectly possible for a snow dragon to be alive and breathing and growing. Though hang on a minute, "What was the snowman like?"
