In a two-part 2010 episode, the actor Kasey Campbell played a teenage Kevin in flashback sequences set in 1986.
Kevin also implied that in his past, he had had problems staying faithful in a relationship and slept around with other random men at times.
Along with the rest of the Walker family, Kevin's world was shaken when his father William suddenly died and was revealed as an embezzler and an adulterer.
A heavy burden was often put on Kevin's shoulders, as he was the executor of his father's estate and his siblings also came to him for legal advice when they found out William had embezzled money from the company pension fund.
While working on a case, Kevin interviewed a key witness, Scotty Wandell (Luke Macfarlane).
She changed her mind during the tournament and they went to the movies instead, where they ran into Scotty and a male companion, Randy Stewart (Ryan Eggold) holding hands.
After jokingly slamming the door in his face, Kevin pulled Scotty inside the apartment in order to take their relationship further.
Scotty bristled at the idea of being "bought" by Kevin, and felt he was being made to feel inferior due to his social status.
When a drunk Kevin apologized to him, they kissed and made up, but Scotty's boss fired him for putting his personal life before the job.
Kevin threatened the boss with an anti-discrimination lawsuit unless he agreed to rehire Scotty, with a bigger salary.
Kitty assured him the Walkers would never let anyone hurt the child, and Kevin (along with their other brother, Justin) agreed to be a sperm donor for Tommy and Julia.
After Kevin joined Tommy and Sarah on a road trip to track down the missing pension fund, their car broke down and they were stranded at a military bar.
The family harmony was strained when Kevin found out that Kitty was going to work for a senator (Rob Lowe) who had voted for a constitutional amendment to ban gay marriage.
In the process, Kevin realized Kitty herself was opposed to gay marriage, although she supported civil unions.
A stung Kevin grudgingly accepted her decision, but was infuriated when Kitty began seeing the senator socially.
Chad Barry (Jason Lewis), a handsome soap star, made the moves on Kevin.
Feeling guilty, Saul told Nora the truth, and the Walkers struggled with how to deal with their new addition.
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.
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.
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.
As a thank you present, Scotty treated Kevin to a private dinner at the fancy restaurant where he worked as a cook.
When Jason returned to town, he told Kevin he'd undergone a spiritual crisis and could not bring himself to call.
Scotty then stumbles upon Michelle, who reacts oddly, and later they find out that she has a child, Daniel, and realize that she lied about her miscarriage.
The stated goal of the show to treat Kevin as an equal to, no better or worse than, the straight characters[3] received praise from critics such as Robert Bianco.
[5] Desperate Housewives, which precedes Brothers & Sisters on ABC, previously featured kisses and bedroom scenes involving Bree's gay son Andrew.
The lack of noticeable backlash from viewers or advertisers was hailed as a positive step in public acceptance of gay characters.
[6] All prior same-sex weddings on American network television, including on Roseanne, Roc, The Drew Carey Show, Spin City, Friends, The Simpsons, Family Guy and Northern Exposure, involved minor recurring or guest characters.
[7] David Marshall Grant, one of the actors in the controversial thirtysomething scene, is a writer for Brothers & Sisters.
In the first pilot, Kevin was named Bryan, a prosecutor played by Jonathan LaPaglia, and gearing up for a custody battle with the ex-wife he left after coming out of the closet.
