As Season 4 of Sullivan’s Crossing unfolds, viewers are introduced to a deeply emotional and dramatic turn in Maggie’s life. Maggie (played by Morgan Kohan) finds herself once again at a crossroads. Just when she and Cal (Chad Michael Murray) thought they had finally weathered the storm, her secret ex-husband, Liam (Marcus Rosner), makes a shocking reappearance. And this time, he’s not going anywhere. His presence not only stirs up Maggie’s emotions, but it also disrupts her newfound sense of peace with Cal, creating an intricate emotional web that Maggie must navigate.

The surprise arrival of Liam sets the stage for a tumultuous fourth season, with Maggie’s life becoming more complicated than ever. As her relationship with Cal strengthens, Liam’s unexpected return forces Maggie to confront her past and question her feelings for him. The core of this season revolves around the tension between the past and present, as Maggie struggles to reconcile her history with Liam and her future with Cal.
When asked about how Maggie feels about Liam’s return, Morgan Kohan offers some insight. “It’s just so out of the blue that Maggie doesn’t know how she feels,” she explains. “It’s completely unexpected, so we kind of figure out how Maggie’s feeling as she’s trying to figure out how she is feeling about it.” This uncertainty encapsulates Maggie’s inner turmoil. The emotions and unresolved questions from her past with Liam come flooding back, leaving Maggie grappling with feelings she’s unsure how to interpret.
A significant part of this season’s narrative is the use of flashbacks, which shed light on Maggie’s past relationship with Liam. “We’ve got a couple in there, and I think it’s really lovely. It’s one thing to hear about someone’s past, but then to really see it and see Maggie in such a different light,” Kohan shares. These flashbacks offer viewers a deeper understanding of Maggie’s character, showing her in a way they haven’t seen before, making her emotional conflict all the more poignant.
As for Liam and Cal, Kohan points out that while they may seem like polar opposites, they share some similarities. Both men are capable, confident, and kind, driven by a desire to do good in the world. Despite the contrast in their personalities and backgrounds, these common traits make them more alike than Maggie might have initially thought.
The arrival of Liam forces Maggie to deal with more than just her personal feelings. She is also confronted with the emotional impact on her relationship with Cal. “She has a lot to unpack and figure out,” Kohan reveals. “Her version of what happens, his version of what happens, there’s always going to be some funny gray area. We kind of get to see that unravel as we go.” This adds a layer of complexity to Maggie’s emotions, as the clash of past and present realities throws her into a state of confusion.
Throughout the season, Cal’s unwavering support for Maggie stands as one of his defining traits, but even his patience and understanding are tested by Liam’s sudden return. “For Maggie, it’s a shame. She’s finally getting grounded in their relationship,” Kohan states. “We’re getting to see Cal and Maggie settle into that version of their life and really moving from a rooted place.” However, with Liam’s presence, things are far from stable. As much as Cal wants to believe in the best of everyone, he finds himself grappling with his own feelings of insecurity and jealousy. Maggie’s struggle with her emotions toward Liam threatens to shake the foundation of their relationship, forcing them both to confront uncomfortable truths.
Adding to the drama is the absence of Sully, a father figure who played a crucial role in Maggie’s life. “He was definitely a support for Maggie, one of the big reasons for her to come back to the Crossing, too,” Kohan reflects. With Sully off-screen in Ireland for the season, Maggie is left to face the turmoil without her usual anchor. Although his absence is addressed throughout the season, it is clear that Sully’s absence leaves a significant emotional gap for Maggie, particularly as she navigates the complexities of her past with Liam and her present with Cal.

Ultimately, Season 4 of Sullivan’s Crossing is about Maggie’s journey toward finding herself amid the chaos. With her past and present colliding, she is forced to make difficult choices that will shape her future. As she contemplates what Liam’s reappearance means for her and her future with Cal, Maggie’s emotional growth takes center stage. The season explores themes of love, regret, and the struggle to move forward while confronting the ghosts of the past. It is a season filled with twists and turns, and viewers will be left wondering if Maggie will ever truly be able to reconcile her conflicting emotions or if the weight of her past will continue to haunt her.
