By default the two female's had a rocky relationship. Due to Feral's insubbordenance, Siryn would be even harder on her. Feral's feelings would turn to hate. Their animosity would come to a pitch when their respective teams would battle eachother. The resulting would have Siryn sustaining massive injuries. Feral would ferociously slash Siryn's throat, incapacitating her and leaving her powerless for a long time to come.
