Gigi shaken. Rex returns to Llanview and proposes to Adriana; she accepts and puts Marcie's ring on her finger – where it is soon recognized by Michael. He rushes to Texas, bringing Todd and the authorities with him, and Tommy is returned to Todd on January 14, 2008. Meanwhile, Rex, Adriana, and Dorian worry that Blair Cramer — Adriana's cousin and Todd's wife – will tell Todd that Rex and Adriana have known all along that the McBains had adopted Todd's son. In early 2008, Rex and Adriana meet Dorian's mysterious new house guest, Charlie Banks. Charlie – who is hiding his identity to conceal his relationship to son Jared Banks — glances idly at Roxy's business card and introduces himself as "Charlie Balsom." He is dismayed to learn that Rex's name is Balsom as well, and Rex inquires as to whether he and Charlie are related. Charlie insists they aren't, and later saves Rex from Todd's long-feared wrath over his son. Rex remains curious about his lineage, asking first Roxy, then his Aunt Corinne, about Walter Balsom's side of the family. Both women are evasive and nervous when questioned about Rex's family tree, and Rex becomes convinced that they are hiding something. When Corinne visits Llanview on January 25, 2008 to congratulate Rex on his engagement, Rex grills her for information, and Corinne reluctantly admits that she has her doubts that Walter Balsom was Rex's father. 2009–12 To stop Rex from looking further, Roxy claims that "Charlie Banks" is his father. She begs Charlie to go along with the story; he ultimately agrees, and reluctantly lets an excited Rex start building a relationship with his "father." The truth eventually comes out, and though Rex is hurt and furious, Roxy evades his questions about his real father. On March 31, 2010, Rex and his sister Natalie are told that Mitch is not Rex's father. Not only that, but Roxy isn't his mother. Allison Perkins, one of Mitch's faithful disciples, switched Rex at birth with Roxy and Mitch's real son, Schuyler Joplin. Believing that Roxy's baby (Schuyler) was going to die, Allison took an infant abandoned at the hospital (who would later become Rex) and passed that baby off as Mitch's offspring. She gave the baby to Roxy to show Mitch, who was in prison at the time. However, when Allison discovered that Mitch's child would be fine, she told her sister, Dr. Leah Perkins Joplin, that it was her baby, but she didn't want it and allowed Dr. Joplin to raise the child as her own. Meanwhile, Gigi has come to Llanview to testify for Marcie in the case against her. Adriana discovers Shane's existence, and suspects that he is Rex's son. Rex refuses to believe it, and Gigi confirms that Shane's father Brody Lovett is a deceased Navy SEAL. Gigi is troubled as Rex begins getting closer to Shane. On March 17, 2008, she admits aloud that Rex is Shane's father. With Gigi a constant presence and Rex getting closer to Shane, Adriana seeks to find some leverage against Gigi. She soon discovers that Brody is alive, and he confirms that Gigi had been pregnant when he met her. Adriana pays him to come to Llanview. Rex and Adriana marry on May 20, 2008, but they soon separate as Rex discovers her many machinations. When Gigi leaves town to pursue the missing Rex to Texas and seems to vanish herself, Brody uses Rex's DNA from a toothbrush to fake a paternity test which "proves" Brody to be Shane's father and protects him from being put into the foster care
