Of course he loves his parents. Or at least, he had wanted to. He's been with them for nearly his entire life, but he barely got to know them, though it's not like he hadn't tried. He never called them his 'foster' parents because they're the only parents he'd ever known. Once upon a time when he was old enough to understand the difference between being fostered and being adopted, he used to dream and hope that they'd actually adopt him one day because that would mean he belonged somewhere.

Foster children don't belong. They just exist wherever they're put until they're put somewhere else.

That never happened either, but he never had the courage to ask why.

There's a sense that Prompto perks up at Iggy's response, his smile genuine. "Great! We could use some that sweet sea air."
