"Sorry." He hadn't thought much about it, but right now it's the least important thing. Prompto gets laid down with a tenderness people might not have expected out of the big man, his hand coming up to brush some of the blond strands back from Prompto's face, looking down over the damage done. There's so much of it. The bruising looks so much worse set against Prompto's pale coloring, but it all speaks of days of torture. What was that fluid that had been being pumped into Prompto? What had Ardyn done?

"Just keep your eyes closed." From his pocket he pulls out one of the few potions he has left, away from Noct's ability to make more, but he'd found machines full of potions and remedies. Those... he doesn't trust as much as Noct's, so he cracks it open and slides a hand under Prompto's head, nudging the cool edge of the energy drink to his lips. "Need you to drink this for me, got it? Slow and steady. We're safe here." One door to defend and that's locked, so it's about as safe as it's going to get at this point.

His thumb moves softly against the back of Prompto's neck, ignoring the tightness in his chest. If he could do every bit of damage to Ardyn that the madman had done to Prompto... he would do it a thousand times over.
