Prompto would've answered, but he was laughing too hard at the idea of chocobo underwear to go with his pjs. His cheeks flushed a little for reasons he didn't know at Gladio saying what the pattern had been. It might have something to do with how the big guy knew.

"Wait, that's not the argument! It isn't whether you'd be cuter in this pjs than me, because.. come on, right?" He jokingly made gesture at himself. "The question is whether you'd look cute. And it's two against one so.."

His gaze shifted to Gladio. "Aren't we all cute though? I mean look at this guy? I mean there was almost a protest over the fact he is wearing whole shirts again." Prompto might have been the one who was protesting but that was beside the point.
