You flinched. It started out normal, Tim talking your ear off about something he’s working on without Bruce’s permission and getting lost in the idea of what he’s making. You seemed fine like always, silent and nodding while accepting your fate.
How was he supposed to know? You never mentioned anything in your past and you didn’t show any signs except the occasional bruise, but you and everyone else always seemed to brush it off as patrol. But now, he feels like shit as you curl into yourself after he raised his hand quickly to make motions.
He started stammering out apologies, holding his hands out and clearly so you can see where they are as he tries to make sure you understand that he’d never lay a finger on you. He loves you and he’d never dream of it, but god he wonders who made you react like that.
