Rosa's head drops and she gives a silent sigh as Borgrim runs past her, and with him her leverage. Yet, she doesn't try to stop him yet, warry of revealing her position.

Spoiler: OoCThe werecrow might well believe himself surrounded. He should realize his squad is gone. Borgrim running away from him may well be construed as a show of good faith. Or he may think we're lucky amateurs running around like headless chicken unable to fly from the seat of their pants, which is closer to reality.
Well, I guess it's time for a persuasion roll: Charisma - (1d20+2).
