He will never admit it, but he likes cheerful optimists/idealists. I present as evidence: his only friend for years being Aymeric "gonna go talk to my dad who will never publicly acknowledge that I'm his son about all the murder and corruption at the heart of our nation's war machine and that'll clear it right up" de Borel who he will fight entire said war machine for with his bare fists if need be, and also the fact that he took one look at Alphinaud and went "well guess I have a little brother again."

By which I mean obviously he will be tsundere at Aerith but I can see them getting along really well rofl.
