Tim fucked up. Now Tam is alone in a League of Assassin base that’s under siege by Spider Assassins, with her only hope of rescue being a single ex-Robin of questionable capacity. Sure Jason had punched Tim in the face, but Tim got punched in the face a lot; it couldn’t be that hard. Highly enjoyable AU where Tim finds catatonic Jason at the Cradle during his time with the league and figures out how to bring him home.
