Roxy hides the gun inside her stuffed beaver Morris that she is selling at the flea market. Former con artist Cutter Wentworth later buys the beaver, but refuses to sell it back to Roxy when she later discovers that he bought Morris. Echo is later blackmailed by Kim when they both confront each other about the beaver and the gun. Kim tells Echo that she won't turn over Rex's gun to the police if she can get the Buchanan fortune back to Clint and to help pay for her friend Stacy's medical bills. Echo later tells Rex about Kim's scam against Rex, but he refuses to give back the money to Clint and to give Kim money to her comatose friend. Despite Rex's refusal to give into Kim's demands though, Echo forges his son's name on the documents to hand over the Buchanan fortune back to Clint. On September 20, 2011, Rex heads back to Kentucky to investigate Kim's sick friend in the hospital, but is distracted by Kim when she lies to him saying the friend was a stripper at the Spotted Pony who was badly abused by her boyfriend and had to stay in the hospital to recover from her injuries. Rex then leaves the hospital disappointed he didn't find any leads on Kim's mysterious friend in the hospital. On October 12, 2011, Echo, Roxy, and Bo tell Rex that they think that he might've murdered Victor Jr., but Rex tells them that he didn't murder him. They also later discover that Rex's gun and the murder weapon that Kim was blackmailing Echo with has disappeared, and later found out that Shane took the gun to threaten Jack with at the cemetery to confront him for being responsible for his mother's death, and that he didn't witness Victor Jr. being murdered because he knocked him out with the gun the night of the murder on the doorsteps of Victor Jr.'s house. Bo and Rex then found Shane and Jack at the cemetery. Bo and Rex also took both Shane and Jack at the police station to question them both about Victor Jr.'s murder. Shane told Bo and Rex that after he knocked out Jack with the gun, he then took Jack to drop him off at the hospital. The next day, both Rex and Shane had a heart to heart talk about promising each other to never keep secrets from each other, and to both move on with their lives after Gigi's death. On October 18, 2011, Rex starts to bond with Cutter's ex-girlfriend Aubrey Wentworth, who apologized to Rex for ratting him out about the gun to the police, and to help him plan for her sister's Natalie's engagement party to help celebrate her upcoming wedding to Brody. They also share the fact that both of them used to be con artists. On October 20 Rex decides to return everything to Clint as a way of his moving on with his life. However, Clint officially acknowledges both Rex and Shane as his family and says that they have a right to live in the family home, telling Rex he can stay at the mansion as long as he wishes. On October 24, Rex is visited by Cutter at Buchanan Enterprises while he is moving out of his office. Cutter tells Rex that Gigi is still alive and will return her to him for the Buchanan fortune. Rex tells Cutter that he's giving back the entire fortune to Clint, even though he hasn't received the paperwork from Clint yet to sign. Cutter tells Rex to let him sign
