And indeed, Prompto does follow. He is silent, until the moment Ignis speaks to him, but even then it's just a quiet, "don't." No, he didn't want to stay, but he knows that right now, there's a limited amount of time to do what they need to do before things get even more crazy. He doesn't want to leave, either, because they're leaving behind Noctis. It doesn't matter that he's dead... for the last ten years, he's been gone and yet not.

Some part of Prompto wants to hold onto that, the belief that Noctis is just a small brush of reality away. It sustains him better than the broken pieces of his heart fallen on the floor of his soul.

He steps into the elevator when it opens, waits for Ignis to enter, pushes the button, then leads his head against the cool metal. His whole body hurts, right down to the core, and it has nothing to do with bruises or blood-dried wounds from their last fight. "...to Hammerhead, first?"
