Casey and Morgan arrive at the apartment complex and find a guard (apparently?) knocked out or dead. Inside, Chuck can't believe the Turners left them holding the bag again. Otto points his gun at him and says it will be the last time. Chuck begs him to let them help them hunt down the Turners, since they betrayed all of them and are the lowest of the low. The Turners come back in with guns, then, and tell Otto to let Chuck and Sarah go. Sarah finishes Chuck's sentence: "... But, they are not without their merits." Casey and Morgan spot the tiger and hide behind a bush, as the Turners say they're showing Chuck and Sarah they're not traitors. Outside, Morgan says Casey is important, but if Morgan dies it's not big deal. Casey sort of shrugs in agreement about that, which is awesome. Morgan says there is a way he can serve his country, though. He's going to lure the tiger into Ellie and Awesome's apartment. He runs and the tiger chases him. Otto hears her growl and turns away just long enough for Chuck to kung-fu flash and he and Sarah knock them out. They end up with guns pointed at the Turners, whose guns are pointed back at them. Morgan runs up the stairs from the tiger and swings on a curtain out the window. I'm not sure why the tiger doesn't follow him, but Casey's there to catch him in his arms. It's very loving. Morgan says he told him he was good for something: Tiger bait.
Back inside, Sarah tells the Turners they have to bring them in, and Swoosie says she would have done the same thing thirty years ago. Fred says she actually would have shot them for what they did. Chuck says that would be justifiable. But unnecessary since they saved them. He lowers his gun, and Fred takes Swoosie's away from her. Sarah lowers hers. The Turners hug, as Chuck and Sarah look on with a little sorrow. Back at Castle, the Turners and Chuck and Sarah are checking in with General Redhead, who tells them they did good work and that their cryptographers (are those like the crypt keeper?) are analyzing Otto's data so the nation's communications network remains secure. General Redhead wants to move on to the Turners and their actions, but Chuck and Sarah come forward on their behalf. Sarah says their double-cross was a triple-cross, and they used that to lure Otto away to their apartment, where they could capture him. General Redhead would expect no less, and hopes Sarah and Chuck learned from them. Chuck says they did. Then the Turners announce they're retiring, to the protests of General Redhead, who says they're the best of the best and wonders who will possibly take their place. Hello, anvil! They look at Chuck and Sarah, and he's honored, all, "Really? Us? Thank you!" General Redhead shuts herself off with no goodbye, then the Turners wish Chuck and Sarah "many happy marriages" on their way out.
