Chris and Duncan

This article focuses on the interactions between Chris and Duncan.

Overview
Like every other contestant on the show, Duncan hates Chris for putting them into life-threatening challenges as well as Duncan's hatred for authorities. Chris, on the other hand, likes Duncan, as he is one of the few contestants that is able to start drama, which will give the show good ratings.

When he continues to taunt Duncan, he approaches him and grabs him by the shirt collar, threatening him. Chris quickly gives up the final marshmallow, and Harold is eliminated. This has caused some speculation that Duncan was supposedly the one who would've been eliminated, but Chris, fearing for his own safety, chooses to bend the rules just once and tell them that Harold has been voted off.

Walk Like An Egyptian - Part 1
Duncan is increasingly annoyed by Chris in the entire episode due to Chris forcing Duncan to sing. He finally snaps and lets out an angry rant about how frustrating the entire day had been, followed by him quitting the game. Chris doesn't seem to mind Duncan's resignation (albeit due to being shocked and slightly threatened by Duncan in the process), but refers to him as "Duncan McQuittypants" later, possibly because it meant Ezekiel could come back to the game to fill in his place, which Chris was not happy about.

Walk Like An Egyptian - Part 2
While in the plane, Chris catches Duncan humming Come Fly With Us while he was having a drink in the first-class area. Duncan denies the accusation, but Chris silently implies that he will be watching him if he does it again. Later, after Ezekiel was eliminated, Chris gives Duncan his parachute and tells him "Last stop for non-contestants." Duncan reminds him that he was supposed to be given a ride home, but Chris says that they're going the other way, so he pushes Duncan off the plane with a grin, telling him to have a happy landing.

Chris makes Duncan sing during the whole episode to make up for all the songs he missed and every time he didn't sing while talking, he would be whipped by Chef. At the elimination ceremony, Chris automatically eliminated the intern instead of Duncan (who had received the majority of the votes), just to keep the current drama alive, since it was "just getting started."
