Markus
(Season 5, episode: "An Ideal Husband") – Scotty comes clean with Kevin, explaining that he had an affair with a man, although careful not to mention his name or occupation. After a brief period of not talking and with Kevin sleeping on the couch, their marriage seems to be on the verge of failure, despite the fact Kevin's mother Nora Walker and sister Kitty Walker try to convince him otherwise. On the night of Nora's charity event, Kevin nicknames a waiter "rob" and leaves, before his brother Justin Walker, who is working the bar, gains knowledge of a waiter to claimed to have had sex with the chef of the restaurant and hoped to succeed again. Justin tells Scotty, who learns that Nora's brother Saul Holden, hired him to work as a waiter that night, although completely oblivious to his part in Scotty's affair. Scotty asks Justin to get rid of him but without Kevin knowing, however Kevin gains knowledge of the fact and attacks a waiter at random, thinking he is the person Scotty slept with. When Justin attacks the real Markus, the whole event watches him leave in a hurry and Justin tries to calm Kevin down.
Scotty and Kevin remain separate until Kevin's sister's (Sarah Walker) daughter, Paige Whedon, asks them for their help on her debating project. Kevin, after a failed attempt to get rid of Scotty from the presence of himself, Paige and Nora, helps Paige. Later on, Scotty shows up at Sarah's house and finds Kevin there. The two were tricked by Paige, who strove to repair their marriage. After a long talk in which they reconcile their marriage, Kevin and Scotty show up at Paige's debate session and start with a clean slate.
