Scott "Scotty" Wandell is a fictional character on the ABC television series Brothers & Sisters. He is portrayed by Luke Macfarlane. His relationship with Kevin Walker (Matthew Rhys) was included in TV Guide's list of "The Best TV Couples of All Time".

Scotty Wandell is a gay man who grew up in Oxford, Mississippi, until he moved to New York City and then later to California to start an independent life because his parents, Wally and Bertha Wandell, didn't accept his homosexuality when he came out. As stated in episode 2.16 Prior Commitments, his parents never used the word "gay" until he told them he was. Scotty has worked many temporary jobs including cater-waitering. He was also a head chef at San Estephe, the five-star restaurant where he interned as an assistant sous chef while attending culinary school in Pasadena. He is currently running his own restaurant with Saul, Kevin's uncle.

Scotty met Kevin Walker at Kevin's law office. He was a key witness to insurance fraud for the company he was temporarily working for as a receptionist. Scotty (who at the time was more flamboyant than Kevin) quickly deduced Kevin's homosexuality and jokingly accused him of being ashamed and trying to "pass" for heterosexual. Kevin held a grudge over Scotty for these accusations, but after Sarah invited him to the family's pool party, Kevin started to enjoy Scotty's presence. After making a date, Kevin had to cancel due to the guilt that his mother Nora imposed on him to get him to go with her to a golf tournament. When she changed her mind, and wanted to go to the movies instead, they ran into Scotty and a man, both holding hands with each other.

Scotty then dropped by Kevin's office to tell him that the male companion was just a friend. They set up another date, and bonded by talking about their backgrounds. Scotty impulsively kissed Kevin, he was put off, and remained distant for the time after. The date ended on a sour note, but the next day, Scotty dropped by Kevin's apartment to apologize for being judgmental and to tell Kevin how much he got to Scotty. Kevin expressed relief that Scotty wasn't perfect and kissed him in front of a neighbor. After jokingly slamming the door in his face, Kevin pulled Scotty inside the apartment in order to take their relationship further.

When Scotty was unable to get off work to attend a charity benefit with Kevin, Kevin offered to pay Scotty's salary for the time he would miss. Scotty bristled at the idea of being "bought" by Kevin, and felt he was being made to feel inferior due to his social status. Coincidentally, Scotty turned out to be a waiter at the benefit. 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. Kevin and Scotty made up.

When Kevin found out the family ranch house was about to be sold, he and Scotty decided to go for a weekend visit, not realizing the rest of his family had had the same idea. During the weekend, Kevin's brother Tommy, who had recently discovered his sterility, asked Kevin for his sperm in order to father a child with Tommy's wife Julia. Kevin turned him down. When Sarah found out she angrily confronted Kevin at the dinner table, and asked Scotty for his opinion. Kevin unthinkingly snapped that Scotty was not family and he should "shut up". He quickly apologized, but a hurt Scotty went home. Kevin confided to Kitty that he didn't want to bring a child into the world because he was afraid the child would be considered different for having a gay uncle as a biological father, and face the kind of suffering he had faced. 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. When Kevin got back to town, Scotty would no longer return his calls. Scotty dropped by the office to accept a settlement check, and Kevin joked that Scotty could take him to dinner since he was now on Kevin's financial level. A hurt Scotty said it had taken him a long time to accept himself, and in only two months, Kevin had made him feel worthless. He then told Kevin to rip up the check. Soon after, Kevin called Scotty and finally put his heart on the line. Scotty asked him for the check, and thanked him for the time they had spent together, but said the relationship was over. Kevin barely held his tears at bay as he ended the conversation.

On Valentine's Day, a mutual friend (Michelle), set up Kevin and Scotty on a blind date, unaware that Kevin was having an affair with Michelle's boyfriend, Chad. With jealously playing up and strong feelings for Scotty, Kevin slept with Scotty that night. The next morning when Chad called Kevin and asked if he slept with Scotty, Chad hung up before Kevin could take the conversation further. Scotty, overhearing this, thought Kevin only slept with him to get back at Chad, which was not true. Scotty wished Kevin good luck then left.

A few months later, Scotty was arrested for DUI. He went to Kevin's office for legal help with the arrest, because he states the officer only arrested him because he 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 - Jason - who he was living with, and who was now away in Malaysia (as a missionary). 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 it. Scotty's tuition then was due, and he 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 (lobster and wine) 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 (soft-shell crabs) 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, and the two moved in together.
