He was about to say something but then Prompto was in his lap and unloading his pain on him. And, like his typical self, he just absorbed it until he mentioned that Clarus layed a hand on him.

"He fuckin' interrogated you?" Clarus. Who'd been there when he'd been given his Crownsguard uniform? Clarus, the big unbearable jerk who woke all of them up for training in the morning? He saw a little bit of red in his vision, but he didn't let go. If anything, it made him more determined to make sure his best bud was alright.

"...Shiva bless that big lug," he breathed out, going back to gently rubbing Prompto's back. He had the best Shield ever and he'd fight people over that, too. "I'll talk to 'em tomorrow," he promised. "Just talk."

No arguing. No punches thrown unless it came down to it but he doubted it. Their family was sworn to protect his so he could vaguely see why... were he sober. But it's Prompto. The big fucking nerd who was too shy to even approach him for eight years or so after they'd first met. Who had a hard time opening up to others and somehow wormed his way into all of their hearts. Was the glue that kept them together after Altissia, his best friend and if Clarus couldn't see that, then...

Yeah. Definitely talking to him when not suffering a hangover.
