Sundae Muddy Sundae

'''The final five take a run throughout the island to create a sundae to feed the host's interns. Someone feeds mistrust between everyone and a planner, forcing them to find some way of surviving either on their own or through an alliance; while another tries to figure out the cryptic meaning of a fallen contestant's final words. Though one appears to reach victory, a twist in the rules leads them to lose completely and ultimately to their just desserts.'''

Plot
The episode begins with Mike, as Mal, tearing apart the spa hotel's bedroom looking for the DVD Alejandro hid. A concerned Zoey joins him, and Mike/Mal uses the excuse that he was watering plants and dropped one..."against the wall." In the confessional, Zoey wishes that she could get into Mike's head, while Mike/Mal evaluates his current situation: the DVD for others to find, Zoey losing her faith, and Mike "on the loose" in his head. The scene switches to wandering Mike and bickering Chester and Svetlana. They come across Vito performing as a ventriloquist, holding a dummy that resembles Mal. Mike asks him to join them to defeat the evil personality, but before he can answer, the puppet becomes possessed and threatens Mike. He takes action quickly, grabbing the doll and smashing it into Vito's chain. With Vito now on board, the group wastes no time advancing to find the only remaining personality - Manitoba.

In the outside world, Chris makes his daily announcement to meet for the challenge. Chef brings Gwen back from exile on his jeep and pushes her off in front of the lodgings. Mike/Mal and Zoey approach, asking her how the night was. Gwen states calmly that while she had a Wooly Beaver after her, she climbed into a tree and fell asleep looking at the stars. This earns an elated hug from Courtney, as Zoey, with Mike/Mal beside her, welcomes her back and goes to meet Chris. Gwen is taken aback when Courtney seems to mock Zoey, the C.I.T. claiming that she felt a "cutthroat" vibe from her. She suggests they shun her, before asking if Gwen is still mad at her for the Cameron situation. After some talk, they promise to take each other to the finale. However, in the confessional, Courtney reveals an alternate plan - one she thinks will guarantee her a first place ranking. Showing the camera a chart, she explains that she will take Scott to the final two, believing that he will forfeit the game. Gwen she intends to go before him, in order to make sure that she doesn't get eliminated prior to that. Mike she admits is a "wild card," but Zoey she wants gone immediately. In the woods, Scott attempts to flirt with Courtney only to humiliate himself. She laughs with Gwen, who couldn't be happier that Courtney has regained her trust in her. Scott then begins to taunt Mike/Mal and Zoey, but is met with something completely unexpected. Mike/Mal exposes the chart, and Scott and Gwen are infuriated as Courtney scrambles to come up with an explanation. Gwen vows to take her down, and Scott swears that he will never forgive her. Courtney ends the chain of confessionals by cursing Mike and assuring the audience that she will not take the Flush of Shame.

The contestants are greeted by Chris, who shows them two starving interns and nonchalantly states that he hasn't fed them all week. To honor their needs, the challenge involves making a sundae out of ingredients placed in various dangerous locations around the island. The winner is the camper whose entire sundae is consumed by one of them. Courtney is fond of this, as she has experience working in an ice cream shop. As the contestants race to the diving cliff, which is covered in manmade snow, she apologizes to Gwen, who calls her "Chartney" and declares that "now it's every woman for herself." Meanwhile, Zoey wants Mike to explain why he did something as "mean" as revealing the chart. He sweetly tells her that the two of them need to stick together, as they are outnumbered thanks to Courtney's friendship with Gwen and relationship with Scott. Mike/Mal states that Courtney "kind of had it coming," leaving Zoey to contemplate Alejandro's exit warning of a "greater evil" among them. On the cliff, Scott pushes Gwen down into the snow, determined not to let Courtney win. He is the first to reach the ice cream snowman, but slides across the ice until he ends up hanging from the cliff. When Gwen claims the lead, filling her bowl and sliding back to the ground, Mike/Mal separates from Zoey and rushes to overtake her. Courtney then asks Zoey for an alliance with, to be declined, and Mike/Mal follows Gwen down the cliff. When Courtney and Zoey reach the top, Courtney taunts Scott and tells him that he'll be the one suffering elimination.

In the swamp, Gwen remains in first place as she approaches the cherries. She is suddenly threatened by an alligator, and Mike/Mal passes her in the race when he forces the animal back down, grabs a cherry, and dunks Gwen into the water as he leaves. Gwen is shocked, labeling him as either "really brave, really bananas, or both," but recovers and stays on his tail. Courtney is next, floating on a log with a swimming Zoey right beside her. Courtney claims a cherry and heads back without trouble, while Zoey becomes the next target of the alligator and soon a bear. Making sure to grab a cherry as well, she shoves a scoop of ice cream into the bear's mouth and flees, as Scott arrives. The scene cuts to Mike and the Main lodge, where the nuts are located...as well as the newly repaired Drama Machine, welding a mallet. When Gwen reaches the lodge, Mike/Mal calls her out and the robot turns its attention towards her. He tops his sundae and walks out performing his signature whistle of In the Hall of Mountain King. When the robot gets its mallet stuck into the wall, Gwen grabs a handful of nuts and makes a quick escape, bumping into Courtney. She apologizes again and begs Gwen not to vote against her at the elimination ceremony. Still wanting to be Courtney's friend, Gwen agrees, on the condition that Courtney vote for herself. Courtney protests, but Gwen offers no alternative and goes on to the next part of the challenge. The latter heads for the next ingredient and screams as she notices the robot, as Zoey swiftly comes in, takes some nuts, and runs. Her place is eventually taken by Scott, who is crushed repeatedly with the mallet, allowing Courtney her topping and escape.

The third ingredient is chocolate sauce, which forms a pool beneath a fire-breathing flower. While Mike/Mal is the first to reach it, Gwen takes back the lead as he waits for Zoey. The two share a conversation and Zoey is ecstatic as she kisses his cheek and leaves to compete against Gwen. Here, Mike/Mal takes a large rock, shoving it into the flower, causing it to explode. The reaction turns the chocolate pool into coal. Scott is impressed though suspicious, but doesn't mind using dirt as an alternative. Courtney, on the other hand, is conflicted, but decides to use the coal as opposed to going without sauce. A bird also vomits on top of her sundae. The scene cuts to Gwen, Zoey, Scott, Mike, and soon Courtney racing to the interns. Courtney is the first to cross and cheers, forcing her sundae towards them. Her plans go awry as Chris announces that at the last second, he is changing this part of the challenge. Instead of feeding the interns, the contestants must eat their own creations until someone cleans their bowl. The others are delighted, even Scott, who considers the dirt a delicacy, and Zoey becomes the winner of both immunity and the stay at the McLean Spa Hotel.

At the elimination ceremony, Courtney again apologizes to Gwen and asks her not to vote her off. Gwen repeats what she said earlier, that she will not do so as long as Courtney votes for herself. She also mocks her sundae and Scott says that he does not trust her anymore. The votes are tallied as being 3-2 with Courtney taking the Flush Of Shame. Chris tells Zoey that the challenge winners can no longer take someone with them to the hotel for an unknown reason, and Mike/Mal is visibly angry. Chris signs the episode off as Zoey tries to fall asleep among an abundance of paintings of him.
