…What if Cor had been more like Prompto after he faced Gilgamesh. Like, imagine a happier bubbly Cor rather than the hardened level headed one he became. Like, he’d settle down eventually probably after saving Prompto from being an experiment and seeing the horrors that the empire was willing to perform on infants I mean what?, but just imagine.
Regis and Clarus, rather than being surprised by the maturity Cor displays after he recovers to being surprised by Cor ACTING HIS AGE.
Cor that still manages to do his job, but regularly runs off to arcades or gets into trouble.
Pranks from him would be scarily well planned. Like. All his training and experience turned against his friends. (Like Regis’s cloak is replaced with one that’s a dark blue instead of black, but only a few people can manage to tell the shades apart. A perfectly timed water balloon falling from the ceiling of a hall while Clarus was only passing through and ends up late to a meeting with Cor.)
Nervous tics. Maybe he chews on his thumb when he’s in social situations. Like, he’s trying to be social but he just never learned how or cared to before. But he would like more friends.
Young Cor actually SMILING.
Dares. He comes up with the worse dares.
“Regis, I dare you to jump from your balcony onto the library roof while you’re only allowed one warp.”
“That’s absurd why would I do that?”
“Knew you couldn’t do it.”
“…Hold my coat Clarus.”
“Regis NO.”
Surprise, he loves sleep as a teenager just like everyone else. And often naps in odd places. (Clarus found him on the top of the citadel with an arm hanging off the edge once. Nearly killed the shield with a heart attack.)
Cor staying up too late and texting his friends at odd hours, from even odder places that only someone with his skills could have gotten to. (A 15 year old with crownsguard training, who thought THAT was a good idea?) Like, imagine the conversations.
“Clarus, look, aren’t those thunderbombs cool looking above the water?”
“How in the infernian’s wrath did you get out of the city Cor?”
Clarus trying to do damage control by tiring him out in training, but the kid, despite his childish antics, has lost absolutely no skill in combat and still gives him a run for his money. Often back fires.
Fist fights. He gets into fist fights with other soldiers regularly over the Immortal nickname.
Pfft, hell, Clarus just ends up being responsible for him in general, and Cor unofficially gets an older brother.
Actually lets people know when he’s scared of something. They never let him live it down that he’s afraid of GRASSHOPPERS. But they also make sure that he’s never burned too badly if caught in a fire attack when they find out he’s afraid of fire.
Keeps candy in his pockets and will throw pieces at unsuspecting people who look like they need a smile. Most often ends up being Regis and Clarus. (Regis mostly gets pelted in the back of the head.)
