The third season of Sullivan's Crossing concluded with a dramatic cliffhanger as Marcus Rosner's character, Liam, revealed himself to be Maggie's secret husband. This revelation came as a shock to Cal, with whom Maggie had been developing a serious relationship, including planning to move in together.

Season 4 will delve deeper into Maggie and Liam's past. Flashbacks will be used to illustrate their earlier romance, which occurred before Maggie moved to Canada. Showrunner Roma Roth teased that the introduction of Liam would create necessary "push and pull" between characters, aligning with the season's theme of "second chances" and exploring love amidst emotional issues.

Actress Morgan Kohan expressed surprise at the marriage twist, admitting she was unaware of its full capacity until late in filming season 3. She acknowledged that Maggie's hesitations with Cal could stem from this undisclosed past. The series aims to balance emotional drama with moments of hope and positivity for its characters.

Beyond his role on Sullivan's Crossing, Marcus Rosner has a notable career in television and Hallmark movies. He also recently transitioned into directing and writing, viewing it as a natural progression from his acting and producing experiences.
