Brody and MacArthur

This article focuses on the interactions between Brody and MacArthur.

Overview
At the very beginning of the race, the two don't have much interactions. However, when they are on the same kart to the airport in Hawaiian Honeyruin, the two develop a steady friendship. Over the course of the race, Brody tries to flirt with MacArthur, who's fully aware of his crush and treats him only as a friend. The two teams work together in some challenges and Brody also helps MacArthur instead of his own team several times. After the Surfer Dudes' elimination, Brody is depressed he didn't get a chance to be with her and gains some weight because of this. Once they return, Brody tries to hit on MacArthur again and become a couple. Their respective teams ultimately face off in the finale and MacArthur invites Brody to a date once he and Geoff win the money in their ending. Though, MacArthur shows no signs of attraction towards Brody in her ending.

Hawaiian Honeyruin
The two teams are on the same kart to the airport with the Rockers and all of them (except Sanders) laugh as the donkey farts. In the ring challenge, Brody and Sanders watch their partners in the challenge and Brody immediately cheers for MacArthur, to a confused Sanders. He then cheers for Geoff instead.

New Beijinging
The Cadets and Surfers team up in the search for the chill zone. When Geoff says they should split up, Brody offers going alone with MacArthur, although Geoff meant each team will go in a different way. MacArthur replies in the interview that she knows Brody has a crush on her and that she can't blame him for that.

Down and Outback
Using Brody's feelings for MacArthur against him, the Ice Dancers trick Brody MacArthur into helping MacArthur after she falls into a pond. Feeling concern of her, Brody leaves the field in order to help her, even though Geoff tries to tell him to focus on the challenge. When the Cadets realize that their bunnies are gone, Brody offer to share some of his to them only to find out that his team's bunnies are gone as well. MacArthur then formulates a plan to capture enough bunnies for both teams, saving them from being eliminated.

Little Bull on the Prairie
After the Ice Dancers and Cadets have gone missing and thus the Surfers are first, Brody says it's probably aliens and proceeds to thank them. Brody tries to impress MacArthur with the bull riding but messes it up again. MacArthur says he has a "nice impact positioning" and he replies by saying he likes her.

Got Venom
The Surfers hear the Cadets scream for help after they get stuck on a tree with komodo dragons beneath them, but ignore them because they didn't recognize their voice and think it's some "princess". However, after Brody hears MacArthur saying that her butt has fallen asleep and realizes it's her, he hurries to help her again and calls her "my princess". He and Geoff try to fight the komodo dragons with sticks but get chased up the tree too. They realize they need to throw something that smells like them in order to escape and MacArthur pulls a piece of her hair that she told was from her pits in the interview, and then gives it to Brody. He kisses it before he throws that and they manage to escape. When Sanders tell them the dragons aren't actual fire breathing dragons, Brody completes the challenge for both teams with ease.

Ca-Noodling
When Geoff and Brody are eliminated, Brody tells MacArthur she'll have to go on without him, to which she has no problem and doesn't show any concern towards him.

Last Tango in Buenos Aires
While the Surfer Dudes are relaxing at the beach, Brody is seen building a sand sculpture of MacArthur in her swimsuit.

Bahamarama
Brody tells MacArthur she looks good and she starts to talk to him back, but when she sees his weight gain, she tells Sanders she wishes she could say the same thing about him. She comments in the interview that she used to think Brody was cool but now not, to which Sanders replies to be superficial. Then MacArthur says she is attracted only to people who are as hot as her. Later, Geoff tells that Brody was bummed he never did something with his crush, but now that they've returned, he can win her over.

A Million Ways to Lose a Million Dollars
When the two teams sail in the lake to find their last travel tip, MacArthur offers him a date for the million but Brody refuses, much to MacArthur's anger. They race for the million and both teams look satisfied in the other's ending, with MacArthur telling Brody to "call her" once he and Geoff win.

Trivia

 * They are part of the first final two teams in the Ridonculous Race history.
 * Not counting the finale where there are two possible endings, both made it first in the same amount of times with four each.
 * This is one of two mutual attractions to not end up as a relationship.
 * Although, unlike the other couple, Brody and MacArthur end on a good note and are possibly dating after the race.
