Tommy Carcetti discusses meeting with the interdenominational ministerial alliance with his campaign staff, Norman Wilson, Theresa D'Agostino and Gerry. Gerry and D'Agostino are against the meeting as they feel that the ministers' endorsement is beyond Carcetti's grasp. Wilson and Carcetti believe the meeting has importance beyond the election and that even if the ministers endorse Royce they may not work as hard for him after hearing what Carcetti has to say.

Homicide unit commander Colonel Raymond Foerster meets with Commissioner Ervin Burrell and his deputy William Rawls to discuss the recent murder of a state's witness. The murder has cost the mayor politically and he has asked Burrell to slow the investigation so that no proof that the motive was the victim's upcoming testimony will come out. Burrell orders Foerster to take the case from veteran detective Ed Norris and instead assign it to Greggs because of her rookie status. Foerster appears emaciated and drained throughout the meeting. Nevertheless, he argues to keep Norris as the investigator and, suspecting Burrell's motives, offers a guarantee that no further details of the investigation will reach the press. Burrell tells him that he resents the implication.
After the meeting Foerster complains to Rawls, who agrees that Burrell's decision to reassign the case is a mistake. Foerster tells Landsman about the order and has him reassign the Braddock case to Greggs despite their shared misgivings.

Omar finds the opportunity to his liking and robs the game while Marlo is playing. He takes Marlo's recently acquired ring along with all of his money.

Randy is caught selling food in the sixth grade cafeteria by Miss Reese and taken to Mrs. Donelly's office. At the office Donnelly is interviewing Cutty for the new job. Rather than act as a custodian she is hoping he will take the job and perform as a truant officer for the school. Because there are no funds available to employ truant officers Donnelly holds the custodian jobs back to pay for them. Cutty recognizes Randy when he is brought in. Donnelly questions Randy about a spate of graffiti based on his fake hall pass. She insists that he tell her who is responsible or she will phone his foster mother, Miss Anna.
Cutty and another man named Marvin begin rounding up children for classes.

Howard "Bunny" Colvin and Dr. David Parenti meet with a politician to discuss starting an in-school program aimed at preventing children from growing up to become repeat violent offenders.

Later the trio meet with the principal and Colvin and Parenti sign confidentiality agreements and safety waivers. After the meeting Colvin meets with the eighth grade head teacher Grace Sampson. She tells him that many teachers view the scheme as the latest splint from city hall. She tells him that the children follow a weekly cycle with their best behavior on Wednesdays where they have spent the most time in the relatively safe environment of the school. Colvin observes some classes and walks the halls. He sees variation in how well classes perform with the best behavior in the younger grades.
