Party girl Christina left a trail of broken hearts behind her on Are You the One?, and now she's bringing her equally sumptuous sister, Emily, to wreak romantic havoc in the Challenge house. Shortly after arriving at The Challenge, it becomes apparent that Christina has her sights set on one of the not-so-single competitors. Worried that her sister is biting off more than she can chew, Emily cautions, "We already have a target on our back because we're the rookies. Christina needs to cool it and watch herself. I don't want her to get hurt." With Christina's risqué behavior, it might be too late for Emily to do some major damage control this time.
