Sullivan’s Crossing Season 3 Ending Explained: Is Maggie Really Married to Liam?

The Sullivan’s Crossing season 3 finale left fans reeling with one of the most shocking twists in the series’ history. Just when it seemed like Maggie Sullivan had finally found peace in Timberlake, a ghost from her past showed up — and dropped a bombshell that could change everything.

Based on Robyn Carr’s bestselling book series, Sullivan’s Crossing follows Maggie (Morgan Kohan), a Boston neurosurgeon whose career implodes after legal troubles. She returns to her hometown in Nova Scotia to reconnect with her estranged father, Harry “Sully” Sullivan (Scott Patterson), and finds herself drawn into small-town life — and into the arms of Cal Jones (Chad Michael Murray).

Here’s a breakdown of the jaw-dropping finale, the fate of other key characters, and what this means for Sullivan’s Crossing season 4.

The Shocking Arrival of Liam

In the final episode of Sullivan’s Crossing season 3, the town gathers to celebrate the reopening of Rob Shandon’s diner. Maggie and Cal are in high spirits, especially after she reveals her plan to open her own medical practice in Timberlake, balancing her professional ambitions with her romantic life.

But their happy moment is shattered when Liam Davies (Marcus Rosner), a man Maggie once called a “summer fling,” appears at the event. He greets her casually — and then drops the line that floors both Maggie and the audience:

“Is that any way to greet your husband?”

Cal immediately asks Maggie for an explanation, but she’s too stunned to respond. The screen fades out on her frozen expression, setting the stage for a tense season 4.

Is Maggie Really Married to Liam?

The episode leaves the question hanging — is Liam telling the truth, or is there more to the story? If Liam is indeed Maggie’s husband, it raises major questions:

• Why did Maggie keep this a secret from Cal?
• Was it a legal marriage or some kind of misunderstanding?
• Who else in Timberlake, including her father Sully, might already know?

The reveal completely changes the trajectory of Maggie and Cal’s relationship. What seemed like a solid romantic foundation now faces its biggest test yet.

Edna’s Health Battle

While Maggie’s love life is in turmoil, another emotional storyline in season 3 revolved around Edna Cranebear (Andrea Menard). After slowly losing her eyesight, she learns that a benign brain tumor is the cause. Surgery could restore her vision but comes with life-threatening risks.

Edna decides to go forward with the operation — on one condition: Maggie must be the one to perform it. In one of the most intense sequences of the season, Maggie successfully completes the surgery, and Edna makes a full recovery, enjoying a heartfelt reunion with her husband, Frank (Tom Jackson).

Sully and Helen’s New Chapter

Season 3 also introduced Sully’s first major romance in the series. His relationship with Helen Culver (Kate Vernon), a writer staying at the Crossing, blossomed over the season. In the finale, Sully announces he’s joining Helen on an extended trip to Ireland.

This marks huge character growth for Sully, who has been reluctant to leave his responsibilities behind. His departure also means the day-to-day operations of Sullivan’s Crossing will now fall to Maggie and Cal — though that dynamic may be complicated by Liam’s sudden arrival.

What the Ending Means for Season 4

Showrunner Roma Roth teased before the finale that “a pretty big shoe” would drop in the closing moments, and she delivered. Liam’s claim could fracture Maggie’s relationship with Cal, reshape her standing in the community, and even bring legal drama back into her life.

Other potential season 4 storylines include:

• How Cal will handle the revelation about Maggie’s past.
• Whether Sully’s absence will change the operations at the Crossing.
• Edna’s journey after her recovery.
• More about Nova Scotia’s tight-knit community dealing with the fallout of this twist.

Will There Be a Sullivan’s Crossing Season 4?

Yes — Sullivan’s Crossing has officially been renewed for a fourth season. CTV announced the news in June 2025, and Robyn Carr confirmed it shortly after on Instagram.

While there’s no premiere date yet, season 4 will likely follow the same release pattern as previous seasons, airing on CTV and The CW before streaming on Netflix, where all three current seasons are available.

Final Thoughts

The Sullivan’s Crossing season 3 ending proved that even in a show filled with heartfelt moments and romance, the drama is never far away. Maggie’s possible secret marriage to Liam is set to be the central tension heading into season 4, promising emotional confrontations, revelations, and perhaps even heartbreak.
