She and Louise warn her she is behaving recklessly and to prepare herself for what is coming. At the precinct, Eddie is “welcomed” back to the force. Pete learns he has been “demoted” to bike patrol and is taunted by Eddie, who tells him he is now unprotected. Eddie questions the call center supervisor about Claudia and tells Lushion he is glad they are partners again, but the latter tells the former he had better straighten up or else. The partners are given the assignment to cover a drug dealer’s murder, but Natalie arrives demanding to speak with Lushion. He promises to talk with her later. When Esperanza arrives Natalie interrogates her about Eddie and if he and Lushion are up to no good. Esperanza promises to get answers without Eddie suspecting anything.

She tells him that the girl he hooked up with in her house stole their daughter’s diamond earrings.

Natalie, Esperanza, and Kelly go to visit Alex at the hospital. They learn she will be released from the hospital the next day. There, Alex reveals she knows about Brad and Marcy hooking up and blames her for everything that has happened. She tells her they are no longer friends and makes Natalie and Esperanza leave as well.
