"Wild" Willie is the proprietor of Wild Willie's Wild Wild West Photography, a shop where guests can pose in vintage-style wild west gear for photographs.
In "A Little Mystery", Jeff and his new friend Colby pose for a photograph, ignoring the interest Willie shows in becoming their friend. When Colby is later murdered, evidence points to Jeff being a serial killer as all of his previous friends had photographs with him at the same stand before vanishing or being killed themselves. Hayley investigates, unaware that it's Willie who's been killing Jeff's friends so he could become his only friend, and Hayley is intended as his next victim. Back home, Roger calls and warns her that she's in danger...of not seeing his new wig. Hanging up the phone, a door creaks open and Hayley discovers a shrine to Jeff. Running for her life with Willie just behind her, she is hit by a car as Jeff comes out of a nearby store.
As Willie prepares to finish the job, Hayley has developed amnesia so Willie leaves her be. Jeff is forced to reintroduce her to their daily life, which takes a slant towards his interests. Going for a photo shoot at the old time photography stand, the flashing of the camera triggers Hayley's memory. She tells Jeff to run for his life, but doesn't understand when she runs out with Willie in pursuit with a gun. He hesitates when Jeff orders him to stop, before realizing that Jeff doesn't have a gun, so he offers to only injure Jeff when he kills his wife and visit him in the hospital. Roger arrives to show off yet another wig, but when he loses it, he becomes distracted long enough to hit Willie with his car. Only injured, Willie is arrested and Hayley and Jeff agree to no more space between them.
