After the Olympics, Morris said he planned to focus on the mixed doubles discipline rather than the team event. He and Lawes committed to playing for at least two more seasons together. However, the two only competed together for one season in 2018–19, winning the Canad Inns Mixed Doubles Classic and making the quarterfinals in the Qualico Mixed Doubles Classic. They were unable to compete at the 2019 Canadian Mixed Doubles Curling Championship, as Lawes had sustained an injury at the 2019 Scotties Tournament of Hearts. During the 2019–20 curling season, Morris played with several different mixed doubles partners, placing 2nd in the Colorado Curling Cup with Kira Brunton, placing 3rd in the MadTown DoubleDown and 5th in the Canad Inns Mixed Doubles Championship with Jolene Campbell, placing 3rd in the Brantford Mixed Doubles Cashspiel with Sarah Anderson, and winning the Qualico Mixed Doubles Classic with Rachel Homan.
