T1, E4: Kelly never understood why her ex Jeremy broke up with her and is looking for answers. Jeremy now dates Julianne, and Kelly is seeing Dominic. But these new significant others aren't strangers - Dominic and Julianne used to date each other back in high school. On night one, Kelly presses Jeremy and gets to the bottom of why they really broke up. Once Kelly gets closure, the X's relax into an easy friendship. The real danger lies in the Bungalow, where the O's flirt and banter like crazy. On day two, the O's forgo spying and choose the seemingly safe basketball activity for their mates - only it turns out to be a racy game of Dare Horse. Then, the O's get the surprise of their lives when they are invited to participate in a Tantric Sex Workshop, which rekindles old feelings between them. But in the end, the original couples choose to stay together, and when Kelly professes her love for Dominic, he realizes it's time to leave Julianne in the past.
