Wendy S. is a meth addict and prostitute who provides sexual services in the parking lot of the Crossroads Motel, which also serves as her home. She appears willing to do anything to get her next fix, be it meth or root beer. While she may seem fragile, she has proven to be tough when she needs to be - whether it is defending the few standards she does have or covering for a well-paying "friend" (Jesse Pinkman) to protect his alibi. However, her lifestyle does appear to be taking a toll on her.
