While the Crawford family is starting to believe that Jess is the killer, Ben signs the divorce papers, but has repaired his relationship with his wife a bit. The two are getting along enough to sit down to a dinner together with their children. While Ben is about to have dinner with his family, he finds a pair of his daughter Abby’s sneakers hidden with blood all over them. She confesses that she killed Tom, that she didn’t want to get in trouble. Abby cries that she and Tom were running away because of all the fighting going on in each of their homes and that it was an accident. Abby said she told Tom that his daddy would come back to his mother if they ran away because parents always come back when their kids are in need. She put on Tom’s mother’s blue jacket and she walked Tom into the woods. Tom dropped his toy tank on the ground and decided he wanted to go home. He started running back home upset and Abby was running after him when she hit him in the back of the head with her dad’s flashlight. She tried to help Tom up and when she saw all the blood, she started screaming for help. She said she ran home to get her dad, but he was already gone running and when he got back he was fighting again with Christy. Abby said she was just trying to keep the family together.

Abby’s older sister Natalie insists they need to tell the police, but Christy wants to protect her daughter and doesn’t want them to say anything. Ben Crawford gets up from the table with the bloody shoes and tells everyone not to go anywhere and to talk to no one. He then says that he’s off to fix it. Ben heads off into the woods as Abby runs behind him, pleading with him. She apologizes to her father and he reluctantly tells her that she made a mistake and didn’t mean to hurt anyone. He then burns her bloody shoes, getting rid of the evidence. However, he looks unsure about his decision. Ben gives Christy the $150,000 she’d been hiding and tells her to take the girls with her and leave. Natalie disagrees with her parents’ decision, refusing to go, and Ben Crawford tells Christy he’s going to give Cornell what she wants. Christy hugs Ben goodbye and leaves with Abby.

Ben Crawford sits down with his daughter Natalie and said he has to take responsibility for Abby because he has to protect her. The two have a heart to heart conversation and Natalie begs him not to protect Abby this way. In the morning, Dave and Ben drop Natalie off at her uncle’s and she cries in her father’s arms, telling him how much she loves him. Dave looks on and cries in the background. Ben thanks Dave for always having his back and Dave tells him that he loves him. He then walks in to the police station and tells Cornell that he confesses to the murder of Tom Murphy.
