In 2015, Josh Wilson and his circle of friends were reunited when Josh Chan moved back to West Covina. He was introduced to the town's latest resident Rebecca Bunch and even fixed her garbage disposal. Together with his crew they assembled a dining table meant to be a surprise gift Chan was giving his girlfriend Valencia. Through Rebecca Josh became acquainted with her boss Darryl Whitefeather whom he met on a Party bus road trip to the beach. He went to a small PPV party Darryl put together which evolved into a larger affair. Wilson stayed behind to help Darryl clean up the mess and when he left kissed him on the cheek. Josh helped Darryl realize he was bi-sexual and after an awkward start they started seeing each other on a regular basis. Together Josh and Darryl attended Jayma Chan's wedding wearing similar tuxedos.
Josh Wilson grew up with Josh Chan, Greg and Hector in West Covina and they remained close friends into adulthood. They were separated when Chan tried to pursue a career in New York City but reunited eight months later when he moved back home. White Josh accompanied Greg and Hector on a late night grocery store run where they bumped into the towns latest resident Rebecca Bunch. Greg introduced Hector and him to Rebecca explaining his nickname was due to him looking like a Caucasian Josh Chan. Wilson added it was also because his name was also Josh. The four of them encountered the other Josh and Valencia and an awkward scene ensued when Rebecca tried to ingratiate herself to Chan's girlfriend ("Josh's Girlfriend is Really Cool!").
When Rebecca called Chan to her house for an emergency White Josh joined him there. The two Joshes learned the emergency was actually a broken garbage disposal. White Josh took a look at it and found that it was overstuffed with chicken. Rebecca changed the subject when White Josh suggested it looked like the clog had been done on purpose. After fixing the problem Wilson claimed it was hot and took of his shirt, to the annoyance of Rebecca. To distract him she gave White Josh her phone to play with and he accessed a pedometer app she had. While Rebecca and Chan talked he improved her step count. He then handed the phone back to Rebecca and left with Chan ("I'm Going on a Date with Josh's Friend!").
Wilson and the rest of the crew were asked by Chan to help him build a dining room table which was a gift for Valencia whom he had just moved in with. They were all at Serrano's house assembling the table since Chan intended this to be a surprise. White Josh and Greg were unsure this was a good idea since Valencia usually had to personally approve anything Chan did. As they struggled to accomplish the task Greg and Wilson tried to subtly suggest to Chan that he break up with Valencia. However, Hector derailed the conversation with a monologue about tandem parking. When they finished putting the table together they presented it to Valencia who, as Greg and Wilson predicted, didn't care for it ("I'm So Happy That Josh Is So Happy!").
Sometime later, White Josh joined the crew and Valencia at the movie theater to watch a film. Afterwards, Wilson and the others convinced Greg to join them for a beach trip. Rebecca Bunch also ended up invited to the outing and she provided the fancy transportation. The assembled group began coupling up leaving Wilson and Rebecca to discuss his work out routine in elaborate detail. When Josh returned from using the restroom he found Rebecca's boss Darryl had joined the trip. The two of them hit it off since Darryl recognized Wilson from the gym he worked out at. The beach trip turned awkward for everyone on board when Rebecca performed a pole dance. Despite the drama that ensued White Josh and everyone else reached their destination and made it to the beach as planned ("I'm Going to the Beach with Josh and His Friends!").
A week later at Home Base, White Josh was hanging out with Hector and discussing with Greg his habit of being commitment phobic. Thoughts turned to a boxing PPV they wanted to watch but couldn't afford just as Darryl walked in. He invited them all to join him at his apartment for a PPV party. White Josh and his friends showed up but they found the boxing event boring and decided to leave. Darryl insisted he could make the party livelier and managed to get a number of pretty ladies to show up. Once the party was over, White Josh helped clean up and Darryl admitted he hired all the women from an online agency. He did this to impress the other guys and become their friend. White Josh told him he could consider him a friend and kissed Darryl on the cheek before he left ("I'm Back at Camp with Josh!").
I feel like you don't take me seriously...like, come on, why haven't I met Madison yet?
–WhiJo, "Why Is Josh's Ex-Girlfriend Eating Carbs?"
Although things with Darryl was going well Josh was concerned about Greg Serrano who had gone missing. He offered his support when he learned his friend had taken time off to deal with his alchohlism. Wilson saw Greg off at the airport when his friend decided to attend Emory University. Josh and Darryl relationship hit a rough patch when they attended the Electric Mesa festival. After seeing Josh's exes there Darryl belived he was just another person who fit a type he liked. Josh himself was worried Darryl didn't take him seriously and only saw him as dalliance. Once they acknowledged their fears to one another they were able to make up. Darryl then officially introduced Wilson to his daughter Madison. When Darryl sold his law firm to Nathaniel Plimpton WhiJo comforted him when he began to regret his decision. He and Darryl attended the stag party of Josh Chan who got engaged to Rebecca. Darryl was bothered when he learned WhiJo didn't believe in the institution of marriage. Darryl eventually accepted WhiJo's beliefs but shocked him by saying he wanted them to have a baby together.
A month after attending Jayma Chan's wedding, Josh and Darryl's relationship was still going strong. It had progressed to the point that Wilson had a key to Darryl's apartment and even had an entire dresser for his things. Josh was also showing up at the firm on a regular basis to bring Darryl his lunch everyday which annoyed Rebecca ("Where Is Josh's Friend?"). Sometime later, Wilson and the other members of the crew were summoned by Greg to Home Base. He had been missing for sometime and finally came out of seclusion to announce to his friend's that he was an alcoholic (♫ Greg's Drinking Song ♫). Greg wanted them all to know that he was dealing with his addiction and WhiJo offered his full support.
They made plans to go to a new ping pong bar that night but Greg was late. Whijo was angry when he found out that Greg's abscence might be due to Josh Chan. The other Josh told their friend he was now sleeping and cohabiting with his ex-girlfriend Rebecca. WhiJo was upset not only by Chan's actions but also because he wasn't told about any of this because everyone thought he'd be to critical. Worried that Greg might fall off the wagon due to the news WhiJo and Hector went looking for him ("When Will Josh See How Cool I Am?"). Although Greg turned out to be okay he decided to finally leave West Covina and to go to Emory University. WhiJo, Chris, Hector and Josh Chan met up at the airport to say goodbye to thier friend.
