In Fairview, Betty insists on keeping Caleb locked in the basement, wanting to protect him from the authorities. One day, however, Caleb manages to escape and sneaks into Gabrielle's house. While searching for Caleb, Matthew meets Danielle Van de Kamp, who flirts with him and suggests they date.

Bree is displeased with Matthew and Danielle's relationship when she learns about Melanie's murder from Betty. Forbidden to see each other, Matthew and Danielle decide Caleb is the problem and devise a plan to get him out of their way. Matthew tells Caleb that Danielle likes him and wants to kiss him. Caleb goes to the Van De Kamp house and into Danielle's room, where Danielle screams for Bree. Bree enters with her gun and frightens Caleb away. Betty realizes she cannot control Caleb and decides to kill him peacefully by crushing pills into a bowl of ice cream. As Caleb eats the ice cream, he tells his mother that Matthew had told him to go to Danielle's room. Furious, Betty takes the ice cream from Caleb and locks Matthew in the basement, but he is soon freed by Danielle. Betty learns that Matthew is really Melanie's killer and informs Bree, who rushes home to find Danielle and Matthew with money they have just taken from her safe.
