Keith is asleep almost immediately. It's one of his talents, honestly. He can drop to sleep in an instant. Staying is sometimes harder. But for now, he's out like a light, especially after the sort of day that he's had, and especially safe and sound and close. At some point as he sleeps, Keith gravitates closer, and then closer.

Shiro is warm and Keith is drawn straight to him, moth to a flame. By the time the older man wakes up, he'll find himself with company closer than before. Keith is tucked up against him, head settled between his shoulders, one arm draped over him.

Honestly it's the best Keith can remember sleeping in a very long time.
