Evan Chambers is one of the main characters in the series. He was the president of the Cyprus-Rhodes University chapter of Omega Chi Delta. During his time in Omega Chi, he was the big brother of Calvin Owens. Evan was the Interfraternity Council (IFC) president and the Omega Chi's representative. He was also a member of the Amphora Society. Although he is attractive, preppy, and wealthy, he struggles to balance the good in him with the cutthroat behavior expected from a Chambers.
During one of his childhood summers, Evan went to Camp Kitchiwawa. There he met and befriended Cappie. Cappie and Evan apparently kept in touch after camp because he only chose to go to CRU after he learned Evan was going to CRU as well.
In his freshmen year, Evan became roommates with Cappie. Evan convinced Cappie, who had no intention of rushing a fraternity, to go on the rush tour with him. When the two of them arrived at the Kappa Tau Gamma house, while Cappie impressed all the brothers at Kappa Tau; Evan failed to impress them. Evan then met Casey Cartwright and Ashleigh Howard at the KT rush party. While Evan went to get Casey a drink, Cappie met and flirted with her until he realized that Evan had already met her and was trying to impress her. Although Evan met Casey first, she ended up being more attracted to Cappie and the two became a couple. He, Casey, and Cappie apparently spent a lot of time together as Casey referred to themselves as the three musketeers.
Evan had already decided beforehand that he was going to rush Kappa Tau and was happy that he got a bid. Since Evan decided to rush Kappa Tau, Cappie rushed as well. He and Cappie were in the same pledge class as Wade Matthews and Beaver. While rushing Kappa Tau, Evan and Cappie spent a lot of their freshmen year looking for the secret meeting place of the Amphora Society. Egyptian Joe gave Evan the nickname, Bing. Evan asked why his nickname was Bing. At first Egyptian Joe didn't want to answer the question, but after Evan pestered him; he explained that Bing was a combination of bid and ding. Egyptian Joe continued saying that the brothers were on the fence about giving Evan a bid and ended up doing so because they wanted Cappie and realized that Cappie would've never rushed without Evan. Knowing that Kappa Tau didn't really want him, Evan de-pledged and rushed Omega Chi Delta, despite Cappie's attempt to convince him otherwise.
During freshmen year, Cappie stood Casey up for the All Greek Ball so Casey went to Cappie's dorm and found Evan, who tried to cover for Cappie but ended up telling her the truth, that Cappie was pre-gaming at the KT house. Evan offered to take Casey to the ball as friends, which she accepted. Cappie arrived at the ball and saw Evan slow dancing with Casey. Cappie accused Evan of betraying him and hitting on his girlfriend. Cappie and Evan got into a fight, but when it was broken up; Casey decided to stay with Evan to make sure he was alright. The fight between Cappie and Evan was the reason why there was no All Greek Ball during their sophomore year. Later, Casey would break up with Cappie and enter in a relationship with Evan thus starting the rivalry between Evan and Cappie.
