"Don't mention it," said Prompto, softly, with a small nod and an even smaller, hopefully encouraging smile as he gave Liz's shoulder a small squeeze. "You guys..." He hesitated a little, still feeling a bit like he didn't really have a hand in any of this (well, besides the one on Liz's shoulder), but also feeling like he couldn't just, you know, stand there the whole time, either. "Wanna move it inside a little more? Couch is nice and comfy, right? Do you need anything, David? Something to drink? Are you hungry?"

He then seemed to realize this kid would have no idea who he was.

"I'm Prompto, by the way," he added, lifting a hand in a small wave.

He probably could have added that he was actually Liz's husband, and everything, but they already had a lot on their plates right now without trying to shove that onto it, too.
