Sometimes, after a particularly dangerous mission, Keith is unable to calm down. The excess adrenaline continues to course throughout his body, and he just… can’t stop moving. It’s not in huge, obvious ways, but more in the sense that his fingers keep twitching unless he taps them against his thighs; in the sense that he can’t stand still and has to continuously shift his position.
On these days, Keith burns off the adrenaline by heading straight for the Training Room and fighting with the bots. Lance catches him once; he scoffs and says that Keith needs to take a break (and mutters something about how “this is why I can never beat him”). Keith agrees with this sentiment; fighting after such a harsh mission is hardly the way to recuperate, and he knows resting is important. But he also knows that he won’t be able to sleep, that he’ll be restless, turning and twisting in bed. There’s no point in staying up and doing nothing, so he may as well get some training in.
On another day, Shiro catches him. Keith doesn’t notice until his simulation is done because unlike Lance, Shiro watches him until the end.
“It’s late,” Shiro says.
Keith nods. “Yeah.”
Shiro approaches him and takes his hand (as Keith drops his weapon), running his thumb across Keith’s knuckles. Until then, Keith hadn’t realized that his hand had still been twitching. But in Shiro’s grasp, it stills for a moment, and Keith no longer feels the irresistible need to move around.
Stumbling a bit, Keith leans into Shiro’s hold.
