It'd totally be productive if they both cried! Didn't Inigo ever want a cry buddy? That wasn't a real thing, but Prompto wished it was. He didn't want to burden Gladio and Noct with this, especially when he knew what they'd say. It wasn't the same being reassured something was true versus actually getting the kind of acceptance he needed from the other person.

As he was wiping his face with the back of his hand, embarrassed beyond words, he realized Inigo was moving away from him. What? Oh god, no! He'd failed so miserably at helping cheer Inigo up he was running away from him! Their friendship was over and he'd tell everyone on the train what a total freak Prompto was and the world might explode and he'd never see chocobos again.

"What?" He stammered, the words not what he'd expected. The promise though has the desire effect of making Prompto attempt some calm while he was left behind. He stared at the door where his friend went and curled his knees up tighter under his chin. Just like a faithful dog, obedient and believing Inigo would come back, he waited. Despite his tears, the purple haired boy immediately got a smile when he returned. He doesn't know why that made him cry harder too, but it did. When his friend was seated next to him, he quickly got dragged right into a hug.
