Ted says that Jamie lied about his whereabouts the night Rosie was killed. Jamie offers to take Richmond back to City Hall with his car.
Back at City Hall, Gwen receives news that Richmond left the house. Holder and Linden immediately suspect that Jamie and Richmond are at Jamie's house. But Jamie has already taken Richmond back to City Hall, up to the office. He announces that they've won the election because Adams is conceding. Richmond starts asking questions. Jamie says Ted is a drunk but also admits to arranging the smuggling of the Indian bones to the waterfront site.

Jamie tries to grab Rosie, they struggle, and Jamie hits Rosie hard enough to knock her out. Back in the present, Jamie argues that Rosie was going to ruin everything. But Richmond asserts that Rosie was alive when she went into the lake. This was nothing but cold-blooded murder. Jamie takes out Richmond's gun and places it on the desk.
Linden and Holder head back to City Hall upon hearing the latest news of the car's return. Upstairs, Jamie starts recounting that he thought Rosie was dead. Rosie jumped out of the car and ran.

Richmond yells that Jamie put him in this wheelchair but Jamie says weakness put him there.
Linden, Holder, and Gwen burst into the office. Linden tries to get Jamie to drop the gun but he swings it over, pointing it at Linden. Holder responds by shooting Jamie dead. Linden ducks out of the way.

Chief Jackson and Ames are being held in interrogation rooms. Chief Jackson will be charged with obstruction of justice. Lt. Carlson appears and while commending the two officers, says there is no solid evidence linking Michael Ames to the murder and that Jackson will never turn on Ames. Linden isn't happy with that though and neither is Holder.
Stan and Mitch take the boys to see the new house. Stan asks Mitch if she really wants to do it. Mitch confirms that the move is okay with her.

Gwen calls with requests of news reports. Richmond says it's time to move on from his wife.
Linden and Holder visit the lake in Discovery Park, the spot where Rosie's body was found. Linden realizes that Jamie never told them how he got the car into the water. She wishes they had, but Holder says they got Jamie. They got the right guy. They decide to tell the Larsen's. When they get to the garage, they only find Terry. But they do see Terry's car, which happens to have a broken taillight covered with tape. Linden face grows weary. She realizes that Terry is involved somehow. Linden heads inside to confront Terry. Terry says she was at the lake. She picked up Michael Ames and was heading to the airport for Las Vegas. But then, Michael Ames got the call about the girl in the woods from Jamie, terrified about what to do. Michael Ames was going to leave his wife for Terry but they couldn't make the flight. Terry drove her car with Ames in it and went to the woods where Rosie was. Just then, Stan and Mitch return and Linden and Holder try to keep them out of Rosie's bedroom. Terry starts getting flustered and says don't be mad at her. Stan realizes that they've been interrogating Terry.
In a flashback, Jamie and Ames are arguing. Michael Ames defiantly states that he doesn't want any part of a murder. Jamie argues that this is the way it has to be and the girl is a nobody. Jamie says to call Janek because he doesn't have the heart to kill anyone. Ames argues that the girl should be kept alive. Terry is in her car. She gets out of her car and gets into the campaign car. She puts the car into drive and the campaign car slips into the lake. Rosie's last screams are heard. Back in the present, Terry says she didn't know it was Rosie, no one said her name.

At the police station, Holder finds Linden in the office with the lights off and returns her badge. Terry didn't want a lawyer. The lab tech returns Rosie's final video and Linden heads to watch it in another room.
Gwen arrives at the office to find Richmond preparing for a meeting. She doesn't know of any meeting taking place, but moments later people arrive. Chief Jackson shakes Richmond's hand and says thanks him for having the charges against her dropped. Gwen is shocked.
Back at their home, Stan and Mitch wake to find the boys watching Rosie's last videotape. Someone left it on their doorstep. On it, Rosie has written on large panels, saying she wants to see the country. She doesn't know where she is going but she'll let them know when she gets there. She says she loves all of them. She smiles again for the camera before it ends.
Holder and Linden are sitting in the car outside the Larsen home, when he gets a call about a new case. A body has been found and they've been assigned the case. Linden gets out of the car. Holder says they got the "bad guy". Linden says, "Yeah? Who's that?". Holder says to keep in touch and drives off alone. Linden sees Stan's van at the garage and quietly walks up the street.
