[Yelling and thumping from wherever Prompto is sleeping isn't exactly an uncommon occurrence- though usually it takes place when Noctis is present also, when the two are goofing off before bed, doing whatever the hell it was to entertain each other. But the distress in Prompto's panicked yelling, the crying out-- it has Ignis immediately sitting up from where he'd been scrunched up on the too-small couch, immediately reaching out from glasses a half-second before remembering they aren't there, before rolling up to his feet.]

Prompto?

[It's only a few seconds before he's found the blonde tangled in sheets and blankets, ankles wrapped up from his squirming, flopped out onto the floor. Ignis quickly crouches, bare feet cold on the hard floor, but he's ignoring that as he reaches out to lay a palm between Prompto's shoulderbl;ades, as though that would help calm and still him.]

Prompto.... relax. Noct is just away right now. Staying with that coworker of his, I believe.

[He keeps his voice careful, even- just like years ago, when Noctis would have nightmares about Tenebrae. He knows how the lines of fiction and reality can blur when still half asleep, how it takes time and patience for someone to rouse fully out of the adrenaline-spike and alarm. And so he patiently stays there, one hand on Prompto's back, the other reaching out to start carefully tugging at the blankets to dislodge them, to let him feel less confined or trapped.]

It's alright, Prompto. You've just tumbled out of bed. Breathe.
