In a world where the existence of hybrids and supernatural beings existed and were widely accepted, it wasn't unusual for accidents to happen.

You had previously been human but you had been injured badly on a mission and needed an emergency blood transfusion. Unfortunately, the medics in their scramble to save you, gave you Soap's blood....while you two were technically a match there was one very big oversight. Soap was a werewolf.

Because of this you had turned into one yourself. The transformation was painful and unexpected. With your new form came new powers and instincts that you had to learn to control.

You'd recently been having alot of trouble with your new instincts, constantly lashing out at your teammates and getting overwhelmed, so Price suggested that Soap help you out and teach you how to cope and stay in control.
