Complete story — includes the ending
When questions about his own role in the body dumping are raised, Gob tells the jurors that Buster is a schemer and that they are right to be suspicious of him. Michael overhears Lucille advising Dusty to destroy evidence that implicates her in the murder of Buster's grandmother Mimi. The video, which Michael intercepts, shows Lucille coaching Buster on how to take the blame for her. When confronted on the stand, Lucille's harsh words restore some of Michael's lost memories of Cinco. Combined with the recent discovery that Lucille 2's messages to him were prerecorded, this convinces Michael that he is guilty of the murder for which Buster is being tried. Lucille chastises Michael for making this confession after the court gets out. She reveals that the video of a plot to supposedly cover up her crime was itself a plot to cover up Buster's crime and that her whispered advice to Dusty was designed to be overheard. Nevertheless, a mistrial is declared. With Buster free, the Bluths gather at the border to unveil a wall being picketed by protesters. One of them is Lindsay whom Lucille embraces as her half sister whom she adopted to raise as her daughter. Gob seizes on the chance to go back to leading a straight life without angering the Gay Mafia and stages a continuation of the closet illusion with Buster as his assistant. Gob disappears and tells the audience members he is inside the wall just as cement is poured between the two layers. George-Michael tells Chinese businessmen that Gob's incapacitation gives him the right to license Fakeblock to them. Michael objects and gets into a fist fight with his son. Being third in the line of succession, this gives him the right to sell the company when George-Michael becomes incapacitated as well. George-Michael gets up afterwards and thanks his father for going along with the plan to increase the valuation of the company by portraying it as significant enough to trigger a father-son fight. When Michael breaks the news, he remembers more from May 5 including the fact that he never killed Lucille 2. Gob's illusion ends by revealing that neither he nor Tony Wonder had ever been encased in cement. Gob's stories about Buster's malice are proven correct when construction workers arrive to retrieve what they think is a mannequin and instead find Lucille Austero's body.
