[Souji flinches a bit from the touch on the side of his head, making a face at Ian for his behavior. It hadn't necessarily hurt, but...
The arm around his waist makes him shiver a bit, though Souji's moving easily to wrap an arm around the back of Ian's neck to hold himself up. He's at least not hurt, neither of them are, but he had been chasing the enemy on foot as fast as he could manage and still hadn't been able to catch up.
As the moments pass, Souji at least seems to be getting a little better. He watches Ian's face, almost as if he's trying to figure out what the other is thinking even when he can't see him.]
I won't be any good to anyone if I can't fight.
[Which... sounds a lot like going back to one of the first topics they'd ever seriously discussed, regarding Souji's insecurities as part of the team.]
