Brooklyn Nine-Nine Wiki

Katie is the friend of Rosa Diaz.

Throughout the Series[]

In The Jimmy Jab Games, Jake Peralta asks Rosa Diaz for her friend, Katie's phone number. After Rosa refuses to give him the number, Jake makes a bet with her: If he wins, Jake gets Katie's phone number. But, if Rosa wins, Jake will never ask about Katie again, and he will pay Rosa 200 dollars.

Jake eventually makes it to the final of the games, but decides to let Amy Santiago win, revealing that he is still hung up on Amy. Rosa then decides to give Katie's phone number, in order to help Jake get over Amy.

In Jake and Sophia, when Terry asks Jake what's happening with his date with Rosa's friend Katie, Jake reveals that Katie is more closed off than Rosa. A flashback is shown where Jake asks Katie how long she has known Rosa, but Katie throws him off.
