Better Call Saul
Saul Goodman and Kim Wexler enlist Wendy's help as part of their scam to discredit Howard Hamlin. Dressed up as Howard and driving his car, Saul picks Wendy up at the Crossroads Motel and they put on a performance for Clifford Main where "Howard" supposedly throws Wendy out of the car rather roughly after having sex with her. Kim later drives Wendy back to the motel and offers her free law services whenever she needs it. Wendy spots what she thinks is undercover cops and points it out to Kim, annoyed because it will impact upon her business. ("")
After getting the false impression that Walter White Jr. was using marijuana, Hank Schrader takes his nephew on a trip to the Crossroads Motel in order to scare him straight. There they encounter Wendy using a vending machine and Hank calls her over to Walt Jr. so that he can harass and question her to show Walt Jr. the harmful effects of drug use. Later she is seen in a motel room engaging in sexual activities with Jesse Pinkman.
After Walter White and Jesse Pinkman escape from Tuco Salamanca in the desert, Jesse hires Wendy to give him an alibi for the previous days: that they had not left the hotel for days, living off vending machine food. The two are picked up for questioning by the DEA and Hank Schrader interrogates both heavily to find more information on why Jesse's car was at Tuco's safehouse. Recognizing Hank from his earlier visit with Walter White Jr., she immediately stops talking, refusing to change her story or give Hank any additional information, stubbornly asking instead for a root beer. ("")
Jesse later recruits her again, this time to deliver poisoned hamburgers to the rival dealers who had ordered the murder of his friend Combo, but fails as Walter warns Gus of the imminent threat on their lives. ("")
Wendy 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.
