Bree Hodge
Bree Hodge and Orson Hodge become engaged in the season premiere, and wed in the second episode of the season. Shortly before departing for her honeymoon, Bree is shocked to see her son, Andrew, featured on a televised special about homeless runaways. She cancels her honeymoon and sets out to find Andrew, but is met with anger and resentment when she discovers him in a soup kitchen. After Bree returns home, Orson realizes how guilt stricken his wife is and tracks down Andrew himself. He succeeds in locating Andrew, buys him lunch, and confesses his identity and motive. Andrew reluctantly returns home the following day and, thanks to Orson's mediation, slowly begins reconciling with Bree. The family decides to attribute Andrew's long absence to attending a Drama Camp.
The big mystery of the season revolves around Orson's past, involving his first wife, Alma, and a murdered woman named Monique Polier. Orson's personal history brings the other housewives together in suspicion. It is slowly revealed that Orson's first wife, a woman named Alma, planned on leaving Orson. How their marriage truly ended is a mystery, but Bree becomes suspicious that Orson killed her. The police find a dead woman's body, believed to be Alma, but eventually discovered to be Orson's mistress, Monique. The discovery of Mike's phone number written on her hand leads the police to become suspicious of Mike and eventually arrest him.
Orson's mother, Gloria, moves in with Orson and Bree around the time that Alma returns, alive and well (she left Orson because of his affair). It is later revealed that Mike's phone number was on Monique's hand because she had plumbing problems. It is also revealed that Gloria killed Monique in "self-defense" after she told Monique to stay away from Orson. Orson is drugged and raped by Alma, who eventually realizes (with some "emotional support" from Orson's mother) that he will never come back to her. Gloria locks Alma in her attic, and begins an attempt to kill Bree. Bree, who has found evidence of Monique's death (a bag of teeth ripped from her mouth), falls off a ladder during her efforts to take a decoy bag of teeth, causing a concussion. Alma escapes the attic, only to fall three stories to her death. Gloria tries to kill Bree, but Andrew comes to the rescue; he left early from the grand opening of Tom's pizza place when Danielle showed up and said she did not have to be with Bree anymore because Gloria came to take care of her. After Andrew rushes home he gets knocked out by Gloria, who tries once again to kill Bree. Orson enters and saves Bree, and Gloria has a stroke, leaving her permanently paralyzed but with full mental capacity. Orson visits her, only in order to let her see him walk out of her door for the final time. Orson also uses a fake suicide note written by Alma and the bag of teeth to exonerate Mike. Bree and Orson finally leave for their honeymoon.
Marcia Cross (Bree) has been absent in the last episodes of the season due to maternity leave. However, in the season finale, Bree returns, and is, to all appearances, pregnant. Bree is faking the pregnancy to cover up the real pregnancy of her daughter, Danielle. We see Bree removing a bag, which was used to make her look pregnant. Danielle, meanwhile is hidden in a remote location. Bree and Orson plan to hide Danielle's pregnancy and purport her future child to be their own.
