[And he knows that isn't what he wants, necessarily, only for Shiro to be safe.] But you know it can't be helped in a war. But I always feel safe, when I know you're there watching my back. I'm glad you're coming back. I'm glad we get to fight together again.
How many times have you saved me? I wouldn't even be here if not for you, Keith.
