Holder is still riding the 108 bus when the shift changes. He asks the new driver if he recognizes Rosie. He does, saying Rosie stood out because there weren't many white girls on this route. She always took it to the end of the line.
Reggie's houseboat. Linden takes a smidge of icing from the cake tasting, then looks back into the box of belongings she was packing up when this case began. She takes out the drawing that she discussed with Holder just three days ago. As she sits down to look at it, she feels something in the pillowcase of Jack's bed. She looks inside and sees cigarettes. She's irritated, but it gives her an idea.
Mitch is looking at the impromptu altar set up at Rosie's locker when Mr. Ahmed finds her. He sits down next to her and introduces himself as Bennet. He says Rosie was the kind of kid that inspired him to be a teacher. "Rosie wanted the world, you know?"
Stan enters Rosie's room and heads into her closet. He riffles half-heartedly through her clothes, reminiscing about each piece. He leans in and breathes in Rosie's perfume. He is startled by Linden, who says she needs to do another check of Rosie's room. She apologizes for what happened at the station. Stan says she should have told them what really happened to Rosie. He walks out angrily. She shuts the door behind him and makes a beeline for Rosie's pillowcase.
Back at the high school, Mr. Ahmed tells Mitch Rosie loved poetry and literature. He hands her Rosie's favorite book.
Back at the houseboat, Rick arrives to find Jack eating their wedding cake samples. Realizing that they're in this together, he challenges Jack to help him finish off all the cake between the two of them. It's probably the first time they've bonded, and at Linden's expense.
Holder follows a kid in a Fort Washington letterman jacket off the 108 bus. He watches as the kid walks down some stairs into a building.
Meanwhile, Richmond meets up with Jamie, who is actually insinuating himself into Adams' campaign to do recon for Richmond. He says Adams hasn't admitted to planting the leak yet, but to give him time. Fake out! Jamie wonders how Richmond knew he wasn't the mole. "Because if you wanted to screw me," says Richmond, "you'd have found a smarter way to do it." Jamie chuckles as Richmond drives off.
Holder steps into the building. There's a Richmond campaign poster and a banner that says "Seattle All-Stars." Holder asks a man in charge if he's ever seen Rosie there. The guy points to a photo and says she used to come in with the guy in the photo. Back at the Larsens, Linden thinks she's reached a dead end. Then she turns on Rosie's globe lamp and discovers a shadow inside. She opens up the lamp to find a letter that starts, "Dear Rosie, You're an old soul trapped in a young body..." What follows is a passage from Beryl Markham's West with the Night --
