He sighs out, what would almost be the usual laughter when they tease each other, his hand squeezing Shiro's other one in a way that's almost body firm and shaky at once.]
Well. We've saved each other, then. [He couldn't even begin to put a count to it, not just for how many times he would just as quickly jump in to save Shiro as Keith can imagine Shiro did for him. That's definitely never even been a question, to him.
When he looks back over to Shiro properly again after a while, he smiles, just a little, his own tone a barely there attempt to lighten the air, much as he means the words. Heh.] ... Yeah. Even promise to keep it that way.
