Chris and Heather

This article focuses on the interactions between Chris McLean and Heather.

Overview
The relationship between Chris and Heather is one of the more heated conflicts between the host and one of the contestants, even if some of it is a result of their clashing egos. Chris, several times, seems to show disapproval of some of Heather's measures for victory and for taking control of the show, yet at the same time seems to help her out in slight ways to keep her on because of her strength as an antagonist. Likewise, Heather shows she really doesn't like Chris' bossy and controlling attitude for being the host of the show and shows her displeasure when she is singled out, including the need to ask for Chris to give her the final marshmallow several times during the first season. As the seasons progressed, the conflict has fluctuated, with many moments where the two get on each other and others where they seem to help each other out for their own mutual goals: Heather's drive for victory and Chris's desire to keep the show as dramatic as possible.

The Big Sleep
After Chris tells the contestants that if they do not reach the finish line, they do not eat, Heather mumbles under her breath saying "I hate him so much!"

Search and Do Not Destroy
With Chris in control of the treasure hunt challenge, it can easily be presumed that he knew that he was giving Heather the key that would lead to the chest containing the invincibility pass (provided she was able to retrieve it, in which she did), thus proving that he saw Heather as a valuable asset to continue forwards on the show (even with the stunt she pulls with Trent in this episode nearly gets her thrown off prior to the revelation).

I Triple Dog Dare You!
Chris tried to persuade Owen to make Heather eat dog food by making him use a freebie so that Heather could do the dare. He also appeared to be happy to see Heather finally eliminated. When Chris is asked about the lack of rules by an enraged Heather, Chris says that its "complicated," but that she is still eliminated. Heather is taken to the Boat of Losers and leaves the island, all the while threatening to sue Chris for everything he has.
