Sullivan’s Crossing Season 4 Arrives This Fall with a Mysterious New Character Shaking Timberlake to Its Core

The idyllic yet drama-filled town of Timberlake, Nova Scotia, is set to welcome Sullivan’s Crossing fans back for Season 4, premiering this fall on CTV, with a U.S. release expected on The CW in early 2026. Based on Robyn Carr’s bestselling novels, the romantic drama has captivated audiences with its heartfelt storytelling, scenic beauty, and emotional twists. Following the explosive Season 3 finale, Season 4 introduces a mysterious new character whose hidden past promises to unravel long-buried secrets, sending shockwaves through the tight-knit community. Fans are already buzzing with anticipation, eager to see how this newcomer will disrupt the lives of Maggie, Cal, and the rest of Timberlake’s residents. 👀🕵️‍♂️

A Recap of Season 3’s Game-Changing Finale

Sullivan’s Crossing centers on Maggie Sullivan (Morgan Kohan), a neurosurgeon who returns to her hometown after legal troubles disrupt her life in Boston. Reconnecting with her estranged father, Harry “Sully” Sullivan (Scott Patterson), and forging a slow-burn romance with Cal Jones (Chad Michael Murray), Maggie has navigated personal and professional challenges while finding her place in Timberlake. The Season 3 finale, which aired on June 22, 2025, left fans stunned with a major cliffhanger: Liam (Marcus Rosner), previously described by Maggie as a “summer fling,” revealed himself as her husband, a secret she kept from Cal and seemingly everyone else.

This bombshell, described by showrunner Roma Roth as a “pretty big shoe drop” in a July 2025 Collider interview, has set the stage for a season of trust issues and emotional turmoil. Maggie’s decision to stay in Timberlake and open a general practice, solidified after successfully performing a high-stakes brain tumor surgery on Edna Cranebear (Andrea Menard), was meant to mark a new chapter with Cal. However, Liam’s claim threatens to upend their relationship, raising questions about Maggie’s past and her honesty. As fans on X have noted, “Maggie’s secret husband? My jaw is on the floor! Season 4 can’t come soon enough!”

The Mysterious New Character and a Hidden Past

While Liam’s return is a significant plot point, early teasers for Season 4 hint at an even bigger shake-up: the introduction of a mysterious new character whose hidden past will “shake the town to its core.” Unlike Liam, who is tied to Maggie’s personal history, this newcomer appears to have broader ties to Timberlake’s history, potentially connected to the Sullivan family or the campground itself. A post on X from August 20, 2025, speculated that this character “has a connection to a character of the past and the series history, but is not someone we’ve met before.” While the identity remains unconfirmed, sources like The News Scroll suggest this character’s past could involve long-buried secrets, possibly related to the ownership of Sullivan’s Crossing or a scandal from decades ago.

The new character’s arrival is expected to amplify the season’s theme of trust, challenging the community’s bonds. Will their hidden past involve Sully’s decisions as the campground’s caretaker, or could it tie to Maggie’s mother, whose absence has been a lingering mystery? The show’s knack for weaving personal and communal drama suggests this newcomer will force characters to confront uncomfortable truths, testing loyalties and reshaping relationships. As Roma Roth told Swooon in July 2025, “There’s never a dull moment at Sullivan’s Crossing. A romance drama series needs to have push and pull between your characters.”

What to Expect in Season 4

Season 4, comprising 10 episodes, began filming in Halifax, Nova Scotia, on August 7, 2025, and is expected to wrap by November 25, 2025, according to Deadline. The season will likely pick up shortly after the Season 3 finale, diving into the fallout of Liam’s revelation and the new character’s arrival. Maggie’s relationship with Cal, already strained by her secret marriage, will face further challenges as they navigate trust issues. Kohan hinted at this in a Swooon interview, saying, “It’s going to be a trust thing to have to build up again because that is a pretty big thing to leave out.” Liam’s claim, whether legitimate or a misunderstanding, will force Maggie to confront her past, possibly revealing details about a brief or impulsive marriage she thought was behind her.

Sully’s decision to travel to Ireland with Helen Culver (Kate Vernon) marks a significant shift, leaving Maggie and Cal to manage the campground. This absence could expose vulnerabilities, especially with external threats like Glenn Perry (John Ralston), who may exploit the situation to undermine the Sullivans. Other storylines include Edna’s recovery from her brain tumor surgery, Frank’s (Tom Jackson) reflections on their limited time together, and the evolving dynamics of secondary couples like Sydney (Lindura) and Rafe (Dakota Taylor), whose differing views on marriage may lead to a breakup, and Lola (Amalia Williamson) and Jacob (Joel Oulette), navigating a long-distance relationship. Rob (Reid Price) and Jane (Cindy Sampson) offer a brighter spot, with their romance poised to deepen.

The mysterious new character’s impact will likely extend beyond Maggie’s personal drama, potentially uncovering secrets about Timberlake’s history. Could they be tied to the campground’s origins or a past betrayal involving Sully or other residents? Fans on X have speculated about connections to “shady new neighbors” or a forgotten scandal, adding to the anticipation.

The Cast and Creative Vision

Season 4 will see the return of core cast members, including Morgan Kohan as Maggie, Chad Michael Murray as Cal, Scott Patterson as Sully, Tom Jackson as Frank, and Andrea Menard as Edna. Marcus Rosner’s Liam is expected to have a larger role, given his pivotal reveal, while Kate Vernon (Helen), Cindy Sampson (Jane), Lindura (Sydney), Dakota Taylor (Rafe), and Amalia Williamson (Lola) are likely to return. The new character’s casting remains unannounced, but their significance suggests a notable actor, possibly with ties to Hallmark or similar romantic dramas, given the show’s casting trends.

Showrunner Roma Roth, also behind Virgin River, continues to guide the series, emphasizing emotional depth and dramatic surprises. Directors like Jonathan Wright and Chris Grismer will maintain the show’s cozy aesthetic, with Halifax’s stunning landscapes enhancing the narrative. Scott Patterson praised Roth’s collaborative approach in a 2023 Us Weekly interview, noting, “She really trusts her actors and she listens.” The series’ ability to balance romance, drama, and small-town charm has drawn comparisons to Virgin River, with both sharing Robyn Carr’s storytelling DNA.
