confront Echo about the necklace, she denies that there is any connection between them. Echo later confronts Clint Buchanan on November 5, 2010 and declares that they are Rex's biological parents. Clint reveals that he had known about Rex for quite some time and that he forged the letters of Rick and Lili to keep Rex from finding out the truth. Clint dislikes and distrusts Rex, whom he considers a "gold-digging piece of trash" like Echo. Echo is wracked by guilt over abandoning Rex, and on November 12, 2010 she publicly reveals that she is Rex's mother. She names Charlie the father to protect Rex from Clint's wrath. Meanwhile, Dorian soon guesses that Clint is really Rex's father, and seeks to prove it. In January 2011, Rex allows Echo to begin spending more time with his family. On January 27, he is shocked when Dorian tells him that Clint is really his father. Though Rex does not believe it, he takes a sample of Charlie's DNA to compare it to his; he ultimately decides not to submit to a paternity test, pretending that he has and stating that Charlie is indeed his father. At Jessica and Natalie's double wedding on February 8, Vimal Patel shocks everyone by revealing that Clint is Rex's father, and that Clint had paid him to tamper with the test. Rex and Charlie are devastated. On April 19, 2011, Rex asks Gigi to marry him and she says yes, because they love one another and also to help give Shane some stability after his bullying by Jack Manning, which almost led him to commit suicide; this was stopped by the interference of Rex and Gigi. On June 29, 2011, Rex and Shane say their goodbyes to a brain-dead Gigi due to carbon monoxide poisoning.

After his emotional goodbye, Gigi is taken away and her heart is given to Clint, leaving Rex a widower. Rex also moves into the Buchanan Mansion (which he took ownership of as part of Clint's assets) along with his son Shane and his biological mother Echo. Rex is now planning on using the assets from Clint to take down the Mannings for revenge. Rex later plans to kill Todd and Jack Manning armed with a gun at the Palace Hotel during the "Vicker Man" movie premiere, but he later chickens out and heads back home to the Buchanan Mansion. After he returns home and drops his revenge plan against the Mannings, Rex starts seeing Gigi's ghost. Rex chases after Gigi's ghost, but doesn't catches her after she runs away from him. Rex later confides in Echo that Gigi might not be a ghost, and that she is probably still alive.
