Stivers and Kellerman burst into Mahoney's apartment.

"Drop the gun, Luther!" Kellerman yelled as soon as he saw that it was aimed at his partner. He also took in the fact that Mahoney looked like he'd been beaten to a bloody pulp. By Meldrick, obviously, since he was the only other person in the room.

"What are you going to do—read me my rights?" Mahoney said, and laughed.

"You have the right to remain silent," Kellerman started, but couldn't go on. Even if they arrested Mahoney, even if they put him in jail, it wouldn't be enough. It wouldn't bring back Tomo Roh or the woman who Mahoney accidentally shot in the park today. Mahoney deserved to die and Kellerman decided that he was going to be the one to execute justice.

But as he aimed for Mahoney's heart, Jessie Porter's face swam before his eyes. He heard his own voice telling her that by selling herself she'd be destroying her life. The way that Benjamin Roh had destroyed his own and his mother's by trying to avenge his father's death.

The way Kellerman would be if he killed Mahoney now. Technically, since Mahoney hadn't dropped the gun, Kellerman would be fully within his rights to shoot him, but he knew that Mahoney wasn't a threat. It might be legal to shoot him dead, but not moral. He wouldn't be able to live with himself if he killed Mahoney.

"Drop the gun," Kellerman said again.

Mahoney just kept laughing.

Kellerman aimed his sights a little lower and squeezed the trigger. Mahoney went down, screaming.

Kellerman had knee-capped him.

"Just a little something for you to remember me by," Kellerman said, smirking, as he stood by and watched Mahoney writhe in pain. "And by the way, Luther, we're the ones who switched the drugs." Kellerman turned to Stivers. "Call it in. It's an officer-involved shooting."

As Stivers called for an ambulance, Kellerman kicked the gun out of Mahoney's reach and went over to Lewis, who looked a bit pale.

"You all right? You have a problem with what I did?" Kellerman asked.

Lewis looked over at Mahoney, then back at Kellerman. He said: "Nope. I just never knew you were such a good shot."

"I've been putting in my time on the practice range," Kellerman said modestly.

A moment later Mahoney bellowed, "You're going to pay, Kellerman!"
