"Oh man, that guy's coming our way." Ribbon's general unfettered attitude was largely a result of the fact that she spent so much time asleep she struggled with distinguishing reality from dreams some of the time - this wasn't helped by the fact that a lot of really crazy shit happened in Ribbon's day-to-day - and dudes falling from the sky wasn't something she wasn't used to, but when they started walking towards you it was a mixed bag. The last one she could remember doing it had the head of a ram and he wound up using his horns to gore her, and while chances were that was one of those instances where it was a dream, it had made Ribbon wary of guys who fell out of the sky.
"Hey, uh... what's up, dude? Can we help you with anything?" Ribbon shifted her position slightly so that if the meteor-boy suddenly grew ram-horns and started charging at them, he'd probably reach Cait before he reached her.
