Sora beams. Honestly, he expects that the soldier will never, ever hurt him. (And to be honest, if they did, he probably wouldn't even be mad.)

He holds out his fist, then taps their knuckles together together briefly. "Bam. There. Now you know how to fist bump." Sora sheathes his knife, then stretches his arms up, resting his hands behind his head. "It's like, a handshake, but you can also do it if something good happens. It's like a really short celebration between friends."
