Will Trent fans, get ready: Season 4 might just shake things up in the best possible way. There’s a rare chance for a familiar face to return — Mark-Paul Gosselaar as Paul Campano, Will’s former foster brother — and it could reignite one of the show’s messiest, most emotional storylines from a completely fresh perspective.
Paul hasn’t appeared on the series in years, but his presence was pivotal in the first season. He wasn’t just a former bully from Will’s childhood — he was a complicated figure whose arrival brought up deep-seated trauma for Will and Angie Polaski (Erika Christensen). Seeing him crash back into the present could create electric tension and open the door to exploring Will’s past in ways the show hasn’t dared yet.
Season 3 left fans on edge, with lives hanging in the balance and Will’s personal life in turmoil. Between Angie’s pregnancy, her battle with sobriety, and the arrival of Will’s biological father Caleb, there’s a lot for our GBI agent to process. Throw Paul back into the mix, and the emotional stakes could skyrocket.
Bringing Paul back would allow the series to examine Will’s childhood from a whole new angle. Their shared past — from cruel nicknames like “trash can” to the unexpected moments of bonding — could bring out sides of Will we haven’t seen before. With Angie entering a new chapter of her life as a mother and Will grappling with his past, having Paul there could serve as both a mirror and a guide, helping him confront memories long buried.
Fans are already imagining the drama: old wounds reopening, unresolved tension boiling to the surface, and emotional confrontations that could redefine Will Trent as a series. The combination of Will’s biological father, Angie’s changing path, and Paul’s potential return could make Season 4 the most emotionally charged yet.
If the writers bring Mark-Paul Gosselaar back, it wouldn’t just be a nostalgic cameo — it could be the key to exploring Will Trent’s past, present, and future in a way that’s messy, gripping, and utterly unmissable.
