Kevin, a 35-year old lawyer, was the fourth child of William and Nora Walker (the siblings are, in birth order, Sarah, Kitty, Tommy, Kevin, and Justin). Kevin's first sexual experience was with a girl, but by the next summer he had sex with a boy, Tucker Booth, at his family's ranch house (Tucker also deflowered Sarah and was the first person to do drugs with Justin, but Kevin likely knew none of this). He also reveals a crush he had on fellow student named Matthew Brown. Kevin admits that he joined every extracurricular activity Brown was a part of, from Future Farmers of America to the golf team. When Kevin was a senior in high school, he began seeing a boy named Danny G. McCullough. Danny's sister found out about the relationship and told Kitty. Kevin swore Kitty to secrecy, but by that Christmas she had told the other siblings. Kevin then told his mother, and she quickly joined PFLAG. Years later, Kevin would express some bitterness at how this had unfolded, saying he had felt like an exchange student in his own home. It has been made clear, however, that Kevin has been out in both the personal and professional aspects of his life since high school.Kevin eventually became a successful lawyer practicing commercial and corporate law, but struggled to gain partnership status within his firm. He would eventually leave the practice of law to become the Chief of Staff to Senator Robert McCallister, eventual husband of Kevin's sister Kitty, despite the difference in their political-party affiliations and certain aspects of their political ideologies. Throughout the series, as the lawyer of the family Kevin has typically been the underlying legal conscience in most the turmoil the family faces, from Ojai Foods matters, to the criminal allegations against Justin and Tommy, and more.Prior to the start of the show and in it's early episodes, Kevin struggled with romantic relationships. Several years before the start of the show, Kevin was in a relationship with another man which ended with enough regret that Kevin kept a framed photo of the two of them in his office. Kevin also implied that in his past, he had had problems staying faithful in a relationship. However, early in the series, Kevin meets Scotty Wandell (Luke McFarlan), a witness in a case he his working on. Scotty quickly deduced Kevin's homosexuality and accused him of being ashamed and trying to pass for heterosexual. Kevin was irritated by Scotty's insinuations, but after Sarah invited Scotty to the Walker home for a pool party, Kevin began to let his guard down. The two began a tumultuous relationship which ended after Kevin made a series of insensitive remarks.After his relationship with Scotty, Kevin met Chad Barry (Jason Lewis), a closeted soap star. The two began a secret affair and, in spite of his better judgment, Kevin developed feelings for Chad. At one point, Chad's 'beard', Michelle, fixed Kevin up for a blind date. The date turned out to be Scotty, to the surprise of both men. The two slept together again and the morning after Chad confronted Kevin about his night with Scotty. Chad claimed he would have broken up with Michelle but no longer had a reason to do so. Scotty, who overheard the conversation, asked Kevin if he'd slept with him to make Chad jealous. Kevin replied, I don't know. A hurt Scotty said Kevin was now in the place he had been in with Kevin - loving someone who doesn't love themselves. He told Kevin he felt sorry for him, and sadly wished him good luck. Although Chad was upset with Kevin, Chad soon began calling him again and asking him for another chance. Michelle called Kevin to warn him that Chad was stringing him along and would hurt him the way he'd hurt other men and women. Eventually, a blogger, Dan Silk, began running stories on his site which exposed Chad. Against Chad's wishes, Kevin called Silk and threatened him with a lawsuit. Silk responded by increasing his attacks against Chad. In his relationship with Chad, he almost convinced the actor to come out, but Chad's manager told him if Chad came out his career would be ruined. Kevin convinced him not to come out. Shortly afterwards, Chad decided against living a lie, but no longer wanted to be in a relationship with Kevin.While Kitty was working on her boyfriend Senator Robert McCallister's Presidential campaign, Kitty met his brother, Jason (Eric Winter). Kitty thought he was smart and witty and a good match for Kevin, and set them up for a date. Due to Kevin's antipathy towards Senator McCallister, Kitty opted not to tell Kevin that Jason was Robert's brother. The two men had a good time on their date until Kevin began insulting Robert. Jason soon became offended and made up an excuse to leave early. When Kevin found out what Kitty had done, he was furious, but when she asked him for help, he used his legal expertise to stop a man who told her he planned to blackmail Robert over something he'd done while serving in the Persian Gulf War. At the end of the season, Kevin met up with Jason again when they had to plan Kitty's and Robert's engagement party. After a few drinks and some banter, they made out in the pantry. To Kevin's shock, not long after the kiss he found out Jason was an ordained Methodist minister. As the party wound down, Jason told Kevin he was a traditional person. While Kevin was not entirely sure how he felt about Jason or the situation, he replied that he could use some tradition in his life. At the start of the second season, it was indicated that Kevin and Jason were involved in a relationship. It was also announced that Jason would be leaving for Malaysia to serve as missionary . While both Kevin and Jason told and shared their love and affections for each other, it was implied that their relationship would undergo some emotional strain. This marks a significance in Kevin Walker, as this is the first boyfriend that he has professed a love for, though it was not his first love declaration: his ex-boyfriend Scotty professed a love for him early on as did his ex-boyfriend Chad Barry.While Kevin waited for Jason to return, he spent his time helping Sarah with her messy divorce and Justin with his painful recovery from war wounds. He was surprised when old flame Scotty showed up at his office for legal help. Scotty had been arrested for DUI and felt he was only charged because the arresting officer had a problem with his homosexuality. Kevin managed to have the case dismissed. As a thank you present, Scotty treated Kevin to a private dinner at the fancy restaurant where he worked as a cook. After the meal, Scotty nearly kissed Kevin before he stopped himself. Kevin somewhat nervously said that he had a boyfriend now. Scotty took this to mean that Kevin really had changed. Kevin left, but later returned to tell Scotty that they'd never had the chance to be friends, and he very much wanted to be Scotty's friend. Scotty was in the middle of a busy service, but told Kevin that was fine with him. When his tuition fee was due, Scotty could no longer afford his apartment, cell phone and insurance. Kevin invited Scotty to live with him. In the meantime, Kevin had not been talking to Jason for quite a while because Jason did not respond to Kevin's calls. Kevin felt emotionally lonely and also realized he still loved Scotty. One night, after a meal and champagne, he and Scotty slept together. A few days later, he finally got a call from Jason. He told Jason he had slept with Scotty and then broke up with Jason. When Jason returned to town, he told Kevin he'd undergone a spiritual crisis and could not bring himself to call. Scotty arranged a meal between the three of them which turned tense. After a quarrel, Jason left, and Scotty moved into his car, as he assumed Kevin no longer wanted him around. The next morning, Kevin convinced him he wanted to continue the relationship.When Scotty cut himself badly and incurred large expenses because he had no health insurance, Kevin suggested they enter a domestic partnership so Scotty could share his coverage. Scotty, stung that Kevin only cared about practicality, rejected the idea. Later, however, upon seeing the struggle his uncle Saul was having as a older gay man without a partner because of his fear of coming out earlier in life, Kevin realized just how special his relationship with Scotty was. He proposed marriage to Scotty who, moved by Kevin's words, happily said yes. They are now married and trying to have a child via surrogacy. Show less «
