[ Robby can read a room--read Peter, and know he needs to be serious (careful) about this conversation. It'd be easy to respond in a light-hearted manner, or to go on about skating demons, make a joke about it, but it wouldn't sit right in the mood Robby feels here. Sees coming from Peter, the way he's more uncomfortable in his own skin than he's ever been.

He doesn't touch his own food, but he doesn't move it. He's too hungry himself to think about putting it aside, but Robby's chewing on his thoughts first before anything else, the best thing to say. This isn't something that should just be dismissed, and Robby rolls his lips slowly together. ]

...he's a demon...who seems interested in fitting in? [ No, maybe that's not exactly right, and Robby's brow furrows some. ] --He doesn't know how to be human.

[ Which, of course not, and maybe Peter doesn't need this outsider perspective on some entity he's been living with (but not engaging with--Robby remembers that detail, and doesn't blame Peter for it). ]

But I'm alright, [ he goes on, spoken after a pause, his words getting slower, more considerate. ] ...What about you? You're living with it.

[ And if he didn't know that Paimon was more of a ... recent-year thing and not longer, he'd wonder how much of his younger life was affected by the demon.

A demon is a good reason to stop going to school. ]
