In the third episode of Young Sheldon season 7, titled "A Strudel and a Hot American Boy Toy," Missy befriends a new classmate named Taylor. Initially, she leads her dad, George, to believe that Taylor is a girl, but her mom, Mary, suspects otherwise. When George questions Missy about Taylor's gender, she claims that Taylor is gay and not interested in her romantically. However, this turns out to be untrue when the episode reveals them kissing. The deception continues as George remains unaware of Missy's true intentions.
Missy's romantic choices may have led her to a unhappy marriage in The Big Bang Theory. She may believe she is succeeding, but in reality, she is setting herself up for failure. This behavior continues as she dates boys in secret without the approval of anyone who truly cares about her, like George. Missy, being Sheldon's twin, can easily get carried away when she is attracted to someone. Without objective people interacting with her romantic partners, Missy is at risk of ending up with bad partners, which may have contributed to her miserable marriage in The Big Bang Theory.

In her final appearance on the nerd-centric sitcom, Missy was expecting her second child and going through a separation from her husband. Her mother's disapproval of Mary's actions on The Big Bang Theory showed how unhappy Missy was. Despite the show's portrayal, the adult Sheldon's narration on Young Sheldon later confirmed that Missy found happiness. The voiceover mentioned that she had a supportive family and friends in her future. Although it's unknown who she remarried, perhaps the prequel will reveal the answer before it concludes.
