Season 4 | Episode 14 | Aired 05/4/08
Lynette and Tom decide to keep the twins' arson in the family, so they punish them with lots of chores. Lynette overhears them say that Kayla should be punished too, since it was all her idea. When Lynette asks Kayla about it, she's unnerved by the girl's eerie calm and convinces Tom to take her to a psychiatrist. She tells Kayla she's there because she can't tell the difference between right and wrong, so Kayla assures her that she does, and that she'll tell the psychiatrist -- and the police -- what the twins did. Lynette hastily informs the pychiatrist they won't be needing his services after all.
Kayla hears Tom and Lynette arguing about her and decides to pull another prank: convincing the twins that she just safely jumped off the roof with an umbrella. Parker jumps and breaks his wrist, to Kayla's delight. They rush hm to the hospital while Mrs. McCluskey stays with the other children.
