[prompto gives him a thumbs up after getting the helmet back]

You know it, Sora. If you ever need anything, just give good ol' Prompto a call. I'll help out with what I can.

[he's just a very kind young adult, who overcompensates for the lack of having any family or close relationships in his life by helping others out, in the most altruistic way possible.]

I'll wait for you to get inside! Make sure you sleep well, okay? And behave in school tomorrow!
