[Avoidant curiosity about something as intangible as an unfamiliar thought is a harder train of thought and emotion to accidentally follow than some of the others. Mostly what he gets is that Sans is curious, and comparing his wings, and something to do with Papyrus's transformation. The same-feel between the wings, besides the weight... It reminds him of early in his own transformation, when his limbs had been more like physical prosthetics, and his torso had been bones encased in metal. By now... If they removed all the circuitry, how much of the last few months would he remember?]

...Well, when you put it like that. Maybe a rocket's not a bad idea! You'll be on standby, for going outside for repairs.

[Solar-powered skeleton with wings and teleportation would surely have an easier time maneuvering in space than the cybone, solar panels or no. He gets enough grit and debris up in him as is, and he's heard a bit about the trash apparently orbiting the planet. Zero-gravity trash... Like tossing him in the old trash tornado, no thanks.]
