- "Guys, you know I’ve been thinking a lot about the Earth. We gotta leave it better than we found it"
Being a former roommate who returned shortly after Coach left, Winston finally comes back from playing basketball in Latvia for two years, completely unaware of anything that has happened in the US for the past two years.
On Winston's first night back at the loft, he goes out with Nick and Schmidt for some drinks and gets wasted. Jess makes him breakfast the next morning and not having met him before, she introduces herself by singing while he is massively hungover. The new roommate relationship gets off to an even rockier start when Jess breaks the TV with a basketball. Winston later helps Jess get her stuff back from Spencer, and when Spencer doesn't offer up Jess' jam shirt Winston joins the guys by putting on one of her hats (they do this to dare Spencer to take the hats off of them).
Winston used to occupy the largest room in the loft, which Schmidt took when he left. He managed to manipulate Schmidt in switching rooms by claiming Schmidt is the new 'top dog'. This offended Schmidt because he felt like it was all a joke, but they later reconciled and earned each other's respect. Winston won the large room back by pulling some reverse psychology on Schmidt by suggesting he keep the big room.
Winston later begins adjusting back to life in the US, and the first things he does is look for a job. He quickly realizes he struggles with small talk in interviews as he has not been keeping up with current events for the last 2 years. He gives himself a crash course on the internet, watching countless youtube videos, and movies. He also has no experience, and cannot make a complete resume (skills in basketball, and love for ducks, which isn't even true). He lands a temp job in Bells, but is quickly fired when he wastes mailing supplies in practicing "Eye of the Tiger." He gets a job as a part time nanny for Schmidt's boss who has a son, Elvin.
Winston had a no strings relationship with Shelby before he left for Latvia. Upon his return, he reaches out and meets up with Shelby, and acts like an ass. She tells him off and that she's not interested and that he doesn't care about her. Winston makes amends by showing Shelby that he wants a real chance at a relationship with her and they start dating. After a while together, Winston pulls away again only to realise that he's really in love with her.
They become 'nauseatingly cute', as the other roommates put it, for a while until they hit a rough patch and realise that they're not really working. They feel the relationship has faded and end things. Afterwards Winston goes through a period of mourning and doesn't date for a while.
Feeling stuck in a dry spell and unable to strike up a conversation with women, Winston happens upon Daisy at the bar, who agrees to coach him on talking to women. She comes back to the loft with the group to play True American and Winston kisses her. They start dating, but the relationship mostly seems to revolve around sex. After a while Winston discovers that Daisy is cheating on him and in the heat of the moment, he takes her cat, the now infamous Mr. Furguson.
Winston and Nick grew up together in Chicago, with Winston considering Nick's unreliable father Walt as a father figure. Nick often times pranked and bullied Winston when they were younger, and the two experienced a lot of adolescent rites of passage together. Before meeting Tran and Furguson, the two consider one another their best friend.
It's implied that Coach and Winston went to the same college, as they played basketball together in college and this is presumable how Coach got to know the other guys.
- Baby, look, I don't want space, okay? I don't want anyone to have space. I want to be standing right in front of you. I want the air that you breathe to be the air coming directly from out of my mouth. I want to be just passing air back and forth between each other until it's mostly carbon dioxide and then we both pass out and die
