They reach the board room where they're discussing strategy for the school trip. It's a televised forum on crime between Richmond and the incumbent, Lesley Adams. Richmond thinks Adams is going to get hammered for being too soft. Richmond turns the subject to an announcement that he secured a key endorsement from fellow City Council member Ruth Yitanes. It hasn't been announced yet, but he's confident that she'll go public the next day. With Yitanes' vote, Richmond thinks he's got the election in the bag.
Back at the Larsen homestead, Holder swaggers up to Mitch to ask where Stan has been since last night. Linden tries to make the dance a little more delicate, but it's clear they're asking if Stan is accustomed to stepping out at night. Mitch insists that he's not and that he was with them all night after they got home late from a camping trip. Linden hands Mitch her card and tells Stan to call when he arrives back home. Unsatisfied, Holder asks one more time if Stan was home the night before. Mitch says she's sure. Holder asks how. "How do you think?" sasses Mitch. As she strides back inside, Linden notices a pink bicycle inside the garage and eyes it, putting together the pieces. She asks Mitch if she has a daughter who went on the camping trip. Turns out, Rosie stayed at a friend's during the weekend, and Mitch hasn't talked to her since Friday.
Over at Fort Washington High School, Rosie's friend Sterling is desperately asking people if they've seen Rosie and texting Rosie, "Rosie, Where r u??? Call me 911! Seriously." Their teacher, Mr. Ahmed, gathers together the students' questions for the candidates in today's forum. The principal interrupts to ask if anyone's seen Rosie. Out in the hall, Sterling lies pathetically that Rosie spent the weekend at her house and might have slept in that morning. The stress of uncertainty gives Sterling a nosebleed. The principal leaves abruptly to wrap up preparations for the political forum, allowing Mr. Ahmed to call out Sterling for lying.
Larsen home. Mitch tells Holder and Linden that she had dinner with Rosie on Friday, then Rosie went to a high school dance. They ask typical follow-up questions about what she was wearing (a pink sweater), whether she had a history of running away, etc. It only puts Mitch on edge, but for now she takes it more as an indictment of her parenting than a sign that something is wrong. Then she gets a call. As she takes it, Linden checks out Rosie's room. It's an explosion of pink, with a butterfly-shaped photo collage. Mitch returns from call and says the school confirmed that Rosie hasn't been seen by anyone since the dance on Friday.
