Due to seeing himself as the only "normal" person on the show, Dave can be critical of people and expects little of them. He is a logical thinker, though a little uptight, and is a complete neat freak and has an intense fear of germs. Dave is easily frustrated by his teammates, believing them (with the exception of Sky and Shawn) to be crazy, and often belittles them. Dave was originally a nice guy although frustrated by his teammates. All of that changed when he became the villain in Lies, Cries and One Big Prize and he lost his sanity. His affection for Sky has made him prone to anxiety over being separated or turned down by her, however, gets over this in the finale. Dave has a tendency to be either easily motivated or easily depressed when it comes to competition and has stated that he hardly had any desire to win or have a plan for the prize money. He is also somewhat oblivious at times. He can be vindictive when betrayed or manipulated, as seen in Lies, Cries and One Big Prize.So, Uh This Is My Team? as one of the fourteen new contestants competing. Upon reaching Pahkitew Island, he is placed on team Waneyihtam Maskwak along with Sky, Shawn, Ella, Sugar, Beardo and Leonard. Dave is immediately frustrated with his team's odd antics and thinks very little of them, believing all of them, save for Sky and, to a lesser extent, Shawn and Ella, to be crazy and worthless. In fact, during the first campfire ceremony of the season, he wants to vote four people off. Despite his complaints, Dave himself isn't helpful in all of the challenges, worried of getting injured or dirty.
During his stay on the island, Dave develops a crush on his teammate, Sky. Wanting to get closer to her, Dave often goes wherever Sky does, including following her to forage for food and trying to partner with her in Twinning Isn't Everything. In addition, Dave also agrees with whatever Sky says, even though he voices against it in the confessional. While Sky is often angry with the mistakes he makes, the two of them nevertheless become closer as the season progresses. Dave eventually gets another admirer in the form of Ella after helping her in A Blast from the Past. Unfortunately, Dave is unaware of her crush and unknowingly breaks her heart after rejecting her in the next episode, leaving Ella sad for the entire duration of the episode until she is eliminated.
Dave's infatuation with Sky begins to affect him. This is first displayed in Mo Monkey Mo Problems when Shawn tries to talk him out of his plan to impress Sky, as she only cares about winning the money. Dave hears him, but waves it off. Although Sky admits that she has feelings for Dave as well, she has something else she wants to say. However, Dave cuts her off before she can finish. When Sky is transferred to the opposing team in This Is The Pits!, Dave is deeply saddened and cries hysterically in the confessional. He still has a glimmer of hope that they can be together regardless. The two of them still help out each other in Three Zones and A Baby. Dave believes that this is a sign that they can still be together. Although he keeps getting injured throughout the episode, the biggest impact to hit him is when Sky gives his position away to Chef and is shot by his meatball launcher. Dave believes that Sky no longer likes him and begin to cry hysterically in the confessional. He even tells Shawn to let him quit the game as "nothing matters to him anymore". Attempting to boost his self-confidence, his friend's, Shawn tells him to win the challenge in order to show Sky that he is not a loser. This works, and with his team using him as a snowboard, they reach the finish line first.
Still listening to Shawn's advice, Dave tries applying this to prove to Sky in Hurl and Go Seek that he is a strong player by trying to finish his Juggy Chunk before her, despite its disgusting nature. Even after Sugar had already won the challenge, Dave and Sky continue to drink their Juggy Chunks, with Dave finishing his faster than Sky. Dave then misguidedly boast about beating Sky. However, Dave is unaware that Sky is angry about losing the pre-challenge and she cruelly yells at him that they will never be a couple. This saddens Dave to the point of crying. Still hoping that they have a shot, Dave tries to find Sky only for him to be rejected again. Angry at the cold rejections, Dave proclaims he doesn't needs Sky before howling like a wolf to exert his "lone wolf" status. He is the first person to be captured by Sugar. While helping her to find the other contestants, he watches two love birds and tells the male not to trust the female. Sugar realizes what has happened and manages to encourage Dave to lead her to where Sky is hiding. After the challenge ends and his stomach is pumped, Dave confesses that he told some of the contestants to vote him off, seeing as his chances with Sky are over. At the Cannon of Shame, Dave tries to say his goodbye to her one last time, but she isn't there. Depressed, Dave tells Chris to fire him away.
Dave returns in the finale as Sky's helper after she turns the slot machine twice and ends up with him both times. Upon finding out about this from Chris, Dave goes into depression again. Sky, determined to make Dave as useful as possible, manipulates him by kissing him, saying that she was upset about him being the helper because she didn't want to be distracted by her feelings for him. With his new found confidence, Dave becomes determined in helping Sky to win the million dollars. At one point, Dave loses his hair after Sky provokes the mechanical kitten from Scarlett Fever to melt the snow they are trapped in.
In the end, Chris decides to make the challenge more interesting by revealing Sky's audition tape to Dave, in which she reveals she has a boyfriend back home named Keith. The shock of discovering that Sky had a boyfriend the entire time causes him to finally lose his patience with Sky. With this, Dave angrily yells at Sky and vows to insure that Sky never gets the million. With the island's weather control at their disposal, Dave and Jasmine activate all of the island's traps to prevent Sky and Shawn from reaching the finish line, as Chris promised to give them half of the million each if neither of the finalists complete in time. Dave, however, is more interested in getting even with Sky and wishes to burn the million dollars she wants so much in front of her. However, one of the finalists manages to reach the finish line in the end, disappointing Dave. It is later revealed that Chris and the other three contestants had accidentally left Dave behind on the island. As Dave sighs for failing, he admits that "it can only get better from here", to which he discovers that Scuba Bear 3.0 is standing right behind him.

Dave's audition takes place in his garage, where he enters from the left and messes up his introduction. He starts over, but continues to fumble over his words and wishes he had written down what he wanted to say. He states that he would have, but the only available pen was chewed on, which grosses him out. Due to this, he walks off again and comes back with disinfectant, which he starts rubbing on himself, and comments that he would be a vicious, cold competitor that only cares about winning the money.
