Alma suddenly arrives to Wisteria Lane, and Bree tries to have a good relationship with her. However, Alma buys herself the old Applewhite house, so Bree wants Orson to get rid of her. Orson tries to convince Alma to leave, but she blackmails him, threatening to reveal that it was he who ran over Mike Delfino in his car and buried Monique. Bree then proceeds to visit her to tell her to move away, but she discovers a picture of Orson and Monique and a bag containing Monique's teeth hidden under the linoleum, where they were planted by Alma. Bree gives Orson the teeth, who plants them back in Alma's house, stating that she will not find them and that she will now leave them alone, or else he will call the police and tell them that Alma murdered Monique and kept her teeth. Later, Orson's mother Gloria and Alma trick Orson into believing Alma was going to commit suicide. When Orson arrives to Alma's house, he is drugged by Gloria so that Alma could forcibly have sex with him. The morning after, Bree tells Orson that Alma raped him, and he finally tells her the truth about what happened with Monique. Orson then goes to Alma's to tell her that he does not need to worry about her anymore. She tells him she may be pregnant, to which he responds that he does not care. Alma then realizes that there is nothing else she can do to make Orson love her. Gloria, however, does not give up and locks Alma in the attic and plans to kill Bree. After Alma tries to escape from her attic through the window, she falls from the roof to her death. Orson discovers her dead body and plants the suicide note and the bag containing Monique's teeth in her house, making it seem to the police that she killed Monique and committed suicide.
