Larsen home. Terry's making Denny and Tommy clean up before their mom gets home. She bribes them with ice cream, so they work. She notices a gerbil or something named Wookiee and asks if he's sleeping. The boys tell her that's what mom said, so she's like, "Uh, okay, we'll let him rest." Tommy asks why their dad's in jail, since he's not the bad guy; shouldn't the bad guy be in jail. Terry does her best, saying the world is screwed up and their dad is a great guy but sometimes you do what you think is right and it's not. The doorbell rings then. It's Linden and Holder, looking for Mitch. Linden heads up with Terry to ask her a few questions, and Holder goes off looking for Belko.

Linden asks Terry who, other than her, has keys to the house. She can't think of anyone but Belko. She says the guy practically lives here, because he has no life. "He's just always around like he thinks he's part of this family or something." She says she told Mitch it's not good that he hangs around the boys so much. She says it's not that she thinks he's a pervert, but he's weird. She compares his personality to the table, which is pretty awesome. Downstairs, Belko says he was home with Bev, which is what he calls his mom. He says he has keys, but he never goes into the house because Mitch would never allow that. He says he only goes into the garage, but he wasn't there that night. Outside, Holder and Linden compare notes; he noticed the shredded hand this time so is sure Belko was part of the Ahmed beat-down.

Belko's home. Linden and Holder are questioning a creepy old lady who says Belko was her "miracle baby." She had him later in life, and he's an only child. It was just the two of them. "He's my little man." She says he's always lived here, but that doesn't mean she's a nun if you know what she's saying. She flirts with Holder, which is gross. I mean, she's in her seventies, and pretty scruffy. She assures them Belko was here Friday night. She shows them his room, and says he's a "good little boy" who always makes his bed. They look around as she tells a story about throwing his cat away for peeing on the bed. Holder spots a collage of Larsen family photos on the ceiling above Belko's bed. His mom seems oblivious as Linden lays down on the bed to look at all the photos. It sure does scream serial killer to me.
