Solomon may be molesting Emma. Mott plants a pair of Emma's underwear in Solomon's toolbox, leading Claire to fire him, to Emma's disappointment and causing her to become distant from her mother as Mott had planned. Unknown to the family except for Emma, Solomon keeps his watchful eyes over them. Knowing that Claire's close friend Marlene had been Michael's ex-girlfriend before he married Claire, Mott suggests to Michael that he arrange a surprise birthday party for Claire, leading Marlene and Michael to meet in secret. Claire accuses Michael of having an affair with Marlene, only to find the party-goers waiting in the next room. A now wary Claire begins to suspect "Peyton's" hand in all of these incidents and suggests to Michael that they should take a family vacation without "Peyton". Mott overhears this and boobytraps the greenhouse for Claire. Marlene discovers Mott's identity, but before she can tell Claire, Mott tricks her into going into the greenhouse, where she is killed by the falling glass ceiling. Knowing that Claire suffers from asthma, Mott empties all of her inhalers. When Claire finds Marlene's bloodied body, she has an asthma attack and is briefly hospitalized. Michael is left distraught over Marlene's death and his wife's condition; Mott attempts to seduce him, but he rejects her. Claire uncovers the truth about Mott, and confronts her while revealing the truth to Michael. They kick her out, and Michael tells Claire to get Emma and Joey so they can head to a hotel for safety. Mott breaks into the house and hits Michael with a shovel, knocking him down the stairs and breaking his legs. She then attempts to fulfill her true goal: taking Emma and Joey for herself, but after seeing Mott assault her mother, Emma outsmarts Mott and locks her in the nursery, declaring that Mott will never be her mother. Mott escapes and finds Solomon in the attic, aiding the kids' escape. She attempts to kill Claire but stops after Claire appears to be having another asthma attack, prompting Mott to mock her. As she tries to take Joey, Claire gets up, having faked her asthma attack, and viciously attacks a stunned Mott, and Solomon distracts her enough for Claire to push Mott out of the window, impaling her on the picket fence and killing her. Touched at how Solomon risked his life to protect her family, Claire welcomes him back,
