You accidentally hits Reid in the face with your bag. He doesn't flinch, doesn't move, doesn't even dodge since he lowers his reflexes around you to about zero. Yet, the second you realize, you're cupping his face and caressing his cheek while you frantically apologize.

He's puzzled almost, until he realizes he can milk this for all of its worth. He's suddenly made out of glass and gripping his jaw like you broke it while you stand between his legs with an ice pack and guilty look. He's getting all the attention he could possibly want and he didn't even have to suck it up and ask. He's practically glowing when you look away, in search of something for the swelling and he's hiding his smile behind his usual blank look when you press a kiss to his forehead.

He lets it go soon after, only to mention how his jaw still hurts amidst a petty argument for good measure, when he wants to win at least.
