Wilt Bozer (Justin Hires) has been best friends with Angus MacGyver (Lucas Till) since childhood after helping MacGyver when being bullied by Donnie Santos.
Bozer and MacGyver bonded over the loss of beloved family members and stayed best friends for years; spending many hours building their tree house as kids and moving in together when coming to LA as adults.
In the beginning of Season 1, Bozer is trying to make it big as a film director in his free time while flipping burgers as a day job. He doesn’t know about MacGyver’s true occupation until he is almost killed by hitman Murdoc (David Dastmalchian) in Episode 1×08 (Corkscrew).
MacGyver manages to convince his boss Patricia Thornton (Sandrine Holt) to hire Bozer for the Phoenix Foundation as a lab tech. He creates masks for undercover missions and works on robot Sparky. Later, Bozer is allowed to join the team on field missions.
Since the Pilot Episode, Bozer was interested in Riley Davis (Tristin Mays) who didn’t return his romantic feelings. In Season 2, Bozer meets Leanna Martin (Reign Edwards) at the Operative Training Center he was sent to. Although forbidden, they start a romantic relationship.
In the Season 2 Finale, Leanna is hired by Matty Webber (Meredith Eaton) for the Phoenix Foundation. Every now and then, she joins the team on field and undercover missions.
Bozer asks Leanna to move in with him. She first answers yes, but then feels unsure about it since this is a “big step”.
