S4E10 · Queen B.

Complete story — includes the ending

Lucille prepares for her trial by preparing a story that she was trying to save Buster by piloting the boat away from shore, with Buster as the 'star witness'. When none of her family show up to the trial for various reasons, Lucille is found guilty and sent to jail as a result of Lucille Austero's testimony against her. In prison, Lucille joins a gang of Chinese women called the Jade Triad, and rises to the top of the gang when she shows them a loophole around the 'No Smoking' rule but they turn on her when she causes trouble among the Triad members. Fearing for her life, Lucille gets herself transferred out of the prison to Lucille Austero's clinic where Tobias becomes her therapist. Lucille at first refuses to try therapy but when Tobias accidentally calls her a 'villain', she rants furiously at him and accepts a part as the villain of his Fantastic Four musical. After Michael signs over his rights to the Bluth Company to Lucille, Gene Parmesan helps Michael tail Gob, whom he believes to be Rebel's secret boyfriend. At Cinco de Cuatro, Lucille plans to board a boat and sail out of the reach of the law but after encountering and rejecting both George Sr. and Oscar, Tobias unwittingly correctly psychoanalyzes her and she decides to return to rehab. Meanwhile, as a resolution to the previous episode's cliffhanger, Herbert Love's boat is saved from destruction after Marky mixes up Lindsay and Tobias' cases.
