In the final scene of The Wrong Missy, we see Missy at a bar, waiting to meet a man from a dating app. He texts that he's wearing a black sweatshirt and hat. When Missy goes to the only person fitting that description at the bar, it turns out to be none other than Vanilla Ice, a rapper from the '90s who was a one hit wonder with a little song called "Ice Ice Baby." Anyone familiar with his playful dirtbag persona knows that he's as perfect a match on paper for the Wrong Missy as the Right Missy is for Tim.
The two start to hit it off, but then Tim appears. He reveals to Missy that Ice isn't the man she's supposed to be meeting from the app, and explains that he was pranking her by pretending to be someone else at the bar, the same way she had done on their first date.
Tim tells Missy that spending time with her opened his mind to new possibilities for his life. He realized that he doesn't want to be a straight-laced guy all the time, that he wants to be spontaneous and have fun. After revealing that he quit his job, he says, "It's only been a couple weeks, but I don't like my life as much without you."
By now, Missy realizes that his sentiments are genuine, and she gladly takes Tim back. After Vanilla Ice declines to join the couple for a between-the-sheets pas de trois, they kiss and make up.
