Judith waited patiently for Derek to give her some kind of communication as to what their next steps were going to be. Her eyes moved to follow his finger and she gave a solemn nod to let him know that she understood and was ready.
While Derek didn't appear to be super comfortable about the idea of splitting up, Judith was used to working on her own and this was nothing new. She had six arrows, so she could miss twice and still have enough arrows to take every last one of them out if something went wrong and Derek was overtaken.
"Psst," she hissed softly to get his attention one last time. When he turned to face her, Judith whispered with next to no sound, knowing he'd still be able to hear it. "Tell me when." She raised her crossbow a few inches to indicate what she meant. Then she nodded one more time to let him know that that was all she needed.
