'Brooklyn Nine-Nine' Season 1, Episode 11: 'Christmas' Recap

Jake and Charles break up a fight between corner Santas, collecting donations on each others' turf. It turns into a big fight when one pulls a knife. Children watch in horror as the two take down the Santas.

At the station, Amy has six presents wrapped for Holt - one for each lesson he has taught her. Holt comes out of his office and announces no gifts for him under any circumstances. He calls Jake into his office. Holt has gotten numerous death threats. He needs to have a security detail with him at all times, and he chose Peralta.

Charles talks to Gina. He's going on a single's cruise, even though he loves Rosa. Rosa, however, has made it very clear that she's not interested in him.

Amy pulls together the group. She wants everyone to dress up and do a Christmas card for Holt. They refuse.

Terry has his psych evaluation to determine if he is ready to get back out there. It's not going well.

Holt tries to escape the hovering Peralta, but he finds him and chases him down. Holt says he chose Peralta because the threat is not real, and he didn't expect Jake to take it seriously. Jake says he will, however. He offers to take him to his mom's apartment so he can work quietly.

He brings him to his "mom's apartment," which is actually a safe house. When Holt tries to flee, Jake handcuffs himself to him.

Gina helps Amy make a Christmas card on the computer, putting everyone's face on ornaments on the tree. The only problem is they don't have a picture of Rosa smiling. Hitchcock tries to help by tickling her, but gets damaged.

Jake makes Holt hang out with him, but there is a knock on the door. It's Charles. Holt texted him requesting him to bring him to his old precinct. Jake realizes he was planning to investigate the threats on his own. Charles panics and handcuffs himself to Holt's other hand.

The go over the threats. Jake gets a theme of swimming from the threats, and Holt realizes it is the Freestyle Killer, who once killed a whole swim team. Holt insists he finds this guy, Haims, alone. He was a brash, rude detective back in the day, and he taunted the Killer. He doesn't want anyone else to get hurt for his foolishness.

Rosa realizes that Amy and Gina are trying to get a picture of her smiling.

Everyone gets involved in the Haims case. They track him to the rail yard. They go there, and flush out the killer, Charles missing his flight. There are gun shots heard, and Jake and Holt run toward them.

The Killer corners Holt and Peralta, but is tackled by Terry.

They get a call on the radio. Charles is down; he took a shot in the butt to save Rosa.

At the hospital, the nurse lets them know Charles will be fine. Amy says she's so glad Terry was cleared, but he admits that Gina pulled him out of the room before he was cleared, and he went off to help Holt. Holt thanks everyone for saving him.

Charles tells everyone he's happy to spend Christmas with them, and Amy gets a photo of Rosa smiling.
