Nobody calls Homewrecker "Samantha". At least not twice! Little is known about Johnston's past... She doesn't bring it up and no one has the cajones to ask, but everyone agrees that something must have happened to her that made her so mean. She was given the nickname "Homewrecker" after she single handedly wiped out an entire terrorist cell during a routine house clearing operation on a small "shake-n-bake" settlement that had been taken hostage by UPP radicals.
