In the penultimate episode of season three, Effie gets arrested for attempted murder for what she did to Lauren. At the start of the finale, Effie finds herself sitting in jail waiting to get indicted, which is part of the feds' plan to eventually get her to flip on Tariq and his now-dissolved crew.
When Monet catches wind of Effie's arrest, she sends someone to her cell to kill her before the feds get to her. Effie manages to survive the attempt but then gets an unexpected visitor: Lauren, who comes looking for answers about why she almost got killed. Effie informs Lauren that because the feds were pressuring her to snitch on Tariq and their crew, she knew she had to take her out before that happened.
Effie asks her to recant in court, though Lauren leaves her in suspense by walking out. But it seems Lauren was somehow convinced, because she completely takes back her original statement to the feds. She then turns the tables on ADA Jenny Sullivan — who's largely to blame for her circumstances — telling jurors Jenny pressured her into saying what the feds needed for their case.
As a result, and with some help from her ex Tariq, Effie doesn't get charged and she's freed from jail. But Tariq's gesture doesn't get them back on good terms. After he previously found out Effie lied about Lauren's death disappearance, he iced her of their drug business and cut ties with her. But Effie gets the last laugh in the end when she secretly joins Noma and the Tejadas to get back in the game.
