| Best Medicine (2026) Finale Review: Port Wenn’s Sister City Deal Turns Shady in Episode 13 Ending Explained. (Credits: FOX) |
So, Best Medicine (2026) wraps up its 13-episode run with a finale that leans fully into what makes the series tick — community chaos, emotional growth, and just enough mystery to keep things spicy. Episode 13, “Norway No How,” doesn’t go out quietly either.
Instead, it delivers a layered ending that blends small-town charm with a looming threat, while quietly pushing its characters toward something bigger. From suspicious visitors to personal breakthroughs, this finale leaves Port Wenn standing… but not entirely safe.
Port Wenn kicks things off on a high note as Norwegian delegates Ludvig and Sigrid arrive to formalise a sister city agreement.
The town goes all-in — decorations, traditions, and even a lively dance at The Salty Breeze. Everyone’s buying into the dream of cultural exchange and economic growth.
Well… everyone except Martin.
From the moment the duo arrives, Martin’s instincts are on edge. While the rest of the town is charmed by Sigrid’s emotional speeches about children and the future, and Ludvig’s easy charisma, Martin notices the cracks. Subtle movements. Strange questions. And most tellingly, a clear lack of genuine interest in the people.
Things escalate when Geneva signs a contract tied to the agreement — one that includes economic development clauses nobody fully questions at the time.
Meanwhile, Martin quietly investigates. He catches Ludvig sneaking in and out of the Salty Breeze freezer, spots drone activity over the bay, and pieces together the truth: this isn’t about friendship. It’s about profit.
The Norwegians are planning to establish a salmon farm — a move that could reshape (and arguably damage) Port Wenn’s natural beauty.
And just like that, the celebratory mood flips into tension.
Alongside the main plot, Mark’s situation brings a surprisingly emotional layer to the finale.
At first, his erratic behaviour — stumbling, mood swings, and constant eating — makes everyone assume the worst. But the truth hits differently: he’s diagnosed with Auto Brewery Syndrome, a rare condition that causes the body to produce alcohol internally.
Instead of brushing it off, Mark isolates himself, even locking himself away and retreating to his treehouse. It’s not just about the condition — it’s about control, guilt, and identity.
When the diagnosis becomes clear, there’s relief, but also growth. Mark returns to himself, not just as Louisa’s ex, but as a genuinely layered character who’s still figuring things out.
Let’s talk about the tension everyone felt.
Martin and Louisa? Still very much there.
The finale subtly builds toward something bigger between them. Louisa’s desire to have a child becomes a turning point, and for a brief moment, it genuinely feels like Martin might step up.
Instead… he does the most Martin thing possible.
He refers her to a fertility specialist.
And not just any specialist — his ex.
Cue the emotional whiplash.
Dr. Montgomery’s arrival adds a new dynamic. She’s sharp, guarded, and clearly still has unfinished business with Martin. Her cold approach to Louisa doesn’t help either, making it obvious there’s more beneath the surface.
It’s messy, awkward, and exactly the kind of setup that screams future drama.
The finale doesn’t tie things up neatly — and that’s exactly the point.
At its core, this ending is about protection vs change.
The Norwegian deal represents opportunity, but also risk. Financial growth versus preserving identity. And interestingly, it’s Martin — the outsider who once disliked Port Wenn — who becomes its strongest defender.
That shift matters.
It shows how far he’s come, not just as a doctor, but as someone who now cares deeply about the people around him.
Geneva signing the contract isn’t just a plot twist — it symbolises how easily trust can be exploited. And with Glendon secretly backing the Norwegians for profit, the conflict becomes internal as well as external.
Then there’s Peter.
His innocent claim that Martin is his father isn’t just a cute moment — it reflects Martin’s growing emotional connection to others. For someone who started off distant and clinical, this is massive.
The finale ultimately says this:
Port Wenn isn’t just a setting anymore. It’s something worth fighting for.
But the fight? It’s only just beginning.

| Fox |
Martin Best: From detached surgeon to reluctant protector of the town. Still awkward in love, but undeniably evolving.
Louisa Gavin: Ready for the next chapter of her life, but caught between independence and unresolved feelings.
Mark Mylow: Breaks out of the “love triangle” label and becomes one of the most emotionally grounded characters.
Elaine Denton: Still chasing her influencer dreams, but more integrated into the town’s rhythm.
Aunt Sarah: The backbone of Port Wenn — warm, grounded, and quietly observant.
Peter Cronk: The emotional heart of the story, bridging Martin’s past and future.
Geneva Potter: Carries the weight of the contract mistake, setting up future consequences.
Glendon: Fully steps into the role of internal antagonist, prioritising profit over community.
Ludvig & Sigrid: Charming on the surface, but ultimately symbolic of outside exploitation.
Best Medicine ends its first season with a tense, character-driven finale as a sister city deal reveals hidden motives.
Martin steps up as Port Wenn’s unlikely protector, while Mark’s health scare adds emotional depth. Romance simmers but doesn’t resolve, and the town faces an uncertain future.
It’s a warm yet sharp ending that balances humour, growth, and quiet stakes.. heartfelt, slightly frustrating, but very promising.
Is there a Season 2 of Best Medicine?
Not officially confirmed. There are strong rumours of a sequel, but nothing locked in yet. Fans are hopeful, but it’s still up in the air.
If it happens, expect fallout from the contract, a deeper town council conflict, Martin vs Glendon tensions, and major development in Martin and Louisa’s relationship. The Norwegian plot could escalate further too..
Is the ending happy or sad?
It’s more bittersweet. The town is still standing, relationships are evolving, but there’s a clear sense of unfinished business.
Did Martin and Louisa get together?
Not yet. The tension is there, but the show holds back — setting up potential future payoff.
Will the salmon farm actually happen?
The finale leaves it unresolved, which is likely intentional. It’s the central conflict moving forward.
Best Medicine didn’t just deliver a medical drama — it built a world that feels lived-in, messy, and surprisingly heartfelt. The finale leans into that identity, choosing character growth over clean resolutions. Whether or not Season 2 becomes reality, one thing’s clear: Port Wenn has found its voice… and it’s not going down without a fight.
