and puts Adriana into mortal danger, Rex comes to her rescue, finally convincing Dorian that he is a worthy mate for Adriana. In 2007 Rex and Adriana's relationship is tested by celebrity baseball pitcher Tate Harmon, who becomes romantically interested in Adriana and manipulates events to get close to her and cause conflict between Adriana and Rex. Jealous Rex's own investigations of Tate prompt Adriana to break up with Rex and start to date Tate, but Rex is later vindicated when Tate is revealed to be a white supremacist responsible for various anti-semitic and racially motivated attacks in Llanview. Rex and Adriana reunite. Rex had been devastated by Jen's murder in May 2005, but the event had cemented his closeness to Jen's best friend Marcie Walsh and to Lindsay. While searching for Todd Manning's infant son, kidnapped at birth by Dr. Spencer Truman, private investigator Rex discovers in 2006 that the child is actually his own godson: Tommy, the adopted son of Marcie and her new husband, Dr. Michael McBain. Familiar with the McBains' devotion to Tommy and knowing that they would be devastated if he were taken away, Rex is unsure of what to do; he is also aware of Todd's volatile behavior, above-the-law history, and selfishness. Perceiving Todd's consideration of his missing son as nothing more than a lost possession, Rex decides to keep the secret. Adriana and later Michael himself become part of the conspiracy to keep Tommy with the McBains. Rex goes as far as faking a death certificate for Todd's missing child to get Todd to give up the search. An unhinged Spencer Truman is murdered on January 26, 2007 and Bo catches Rex holding the murder weapon. Rex is exonerated, but Bo and later Michael's brother Detective John McBain suspect he is keeping something from them. In the wake of Spencer's death, hints to the whereabouts of Todd's son begin to surface, prompting Todd to resume his search. In 2007, Spencer's killer is finally revealed to be Lindsay, who loves Marcie like a daughter. Lindsay had discovered Tommy's true identity and had stabbed Spencer to bury the secret forever. But at the same time Lindsay is arrested, the rest of Spencer's final plan plays out as his heir Miles Laurence gives Todd proof that Spencer orchestrated the adoption of Todd's son by the McBains. Realizing that he had been deceived by Rex, Todd swears to get revenge once he has his son back. Rex in turn vows to do all he can to help Lindsay, and to keep Tommy away from Todd. Todd is awarded custody on October 9, 2007, but Marcie flees Llanview with Tommy. The search leads Rex to the Bon Jour Café in Paris, Texas, where he runs into waitress Gigi Morasco — his high school girlfriend. Rex apologizes for his sudden disappearance from her life in 2002 when he had left for Llanview, but does not realize the extent to which she had been hurt. The evasive Gigi, who is hiding Marcie and unaware of her friendship with Rex, lies about any knowledge of the fugitive. Agreeing with Rex that "it is a terrible thing for a father to not have the opportunity to watch his son grow up," Gigi says she has something to tell him. But she holds back as Rex mentions his plans to propose to Adriana; with Marcie anxious to get cash to leave the country, Gigi sells Rex Marcie's engagement ring. Gigi is unnerved as Rex and her son Shane — whose father she has told Shane is dead – nearly meet. Rex departs, leaving
