Complete story — includes the ending

Due to increasing animosity with his roommate Paul over the ownership of 'Fakeblock', George-Michael is voted out of his dorm room. George-Michael runs into Gob. Gob is able to sell a Sudden Valley home to George-Michael, who buys the house so his father will be proud of him. Rebel visits George-Michael and starts doubting their relationship, seeing the investment in real estate as a sign that George-Michael is not as easy-going as he claimed. Maeby, meanwhile, wanting revenge on George-Michael for firing her, advises Michael on how to impress Rebel. Following her advice, Michael makes love to Rebel, but after leaving her apartment he discovers from a photo that his romantic rival is his own son. Upon accidentally running into George-Michael and hearing from him that he has girlfriend-trouble, Michael takes pity on his son and decides not to reveal the truth and gives up pursuing Rebel further. At Cinco de Cuatro, Gob is in negotiation with a Mongolian horde he hired to build the Mexican wall, but as George Sr. reveal they have no money to pay the horde with, the horde is angered and goes on a rampage, being mistaken for rioting Mexicans in the process. Somewhere else, George-Michael is preparing to reveal at his keynote speech that 'Fakeblock' doesn't exist, he finds a note that promises him he will get "screwed" if he continues his plans with 'Fakeblock', and thinking that it is a promise of sex from Rebel, he decides to continue the lie. But, unbeknownst to him, the note was actually a threat from the hacktivist group, Anonymous. Michael awakes the next day, and because he was drugged by Gob, he has forgotten that he decided to give up Rebel. George-Michael, meanwhile, tells Rebel that he truly cares about her and thereby solidifies their relationship. As George-Michael leaves Rebel's place, he runs into the amnesic Michael, and realizes that he was the other guy Rebel was seeing. George-Michael is willing to pass it off as an honest mistake, until Michael inadvertently mentions the photo he saw, revealing that he knew about George-Michael and Rebel's relationship. Angered, George-Michael punches his father in the face, and the two silently stare at each other. In the post-credits scene, Gob is named as the replacement President of Bluth Company after Lucille Austero disappears. Buster is arrested for the murder of Lucille Austero. After watching the news of Buster's arrest, Ron Howard and Brian Grazer decide to make a movie about it.
