In their opening interview, Erin and Corey said that they had joined the show for a number of reasons. They said they knew how to get on each other's nerves and after nearly two years together, they had some stuff to work through. Erin admitted, "I like to be shady. If I don't want to answer you, you're going to know it."
In earlier episodes, as the couple went their separate ways, Corey said, "I know I need to be happy with myself before we can be happy as a couple. You are the best thing that has ever happened to me. I would hate to lose you" (via TV Shows Ace).
Meaww, meanwhile, reported that Erin and Corey joined the show for different reasons. The publication said that while Erin hoped that Temptation Island would show her if there were any missing pieces in their relationship, Corey hoped to get some needed quality time together.
