Maybe this is set after Bane and Knightfall and she's currently the only Bat member still patrolling? Could have Bruce have gone missing with Dick busy in Bludhaven or the Titans, Tim only beginning his own investigation into the missing dynamic duo and Damien as a potential big bad for Batwoman to seek help fighting? Maybe she pulls Ollie out of prison to help her after Damien hospitalises Dick? Lord what if they introduce Jason Todd as the Red Hood as her first nemesis?!
