Spoiler warning: This article discusses events through Best Medicine Season 2, Episode 1.
Martin has a blood phobia because blood has become tied to the unresolved trauma surrounding his sister Rosemary’s death. His reaction is not evidence that he misunderstands medicine. It is an involuntary response that can break through even when his clinical judgment remains precise.
Season 2 makes the secret public when Martin announces it to Port Wenn before Glendon can expose him. The admission explains a contradiction built into the character: he can diagnose a difficult case quickly and still be physically overwhelmed by the sight connected to his profession.

Rosemary’s death links blood with helplessness
Rosemary’s loss sits behind the fear rather than serving as a simple plot fact that switches it on and off. An operation involving a young girl who reminded Martin of his sister sharpened the association. The result is a trigger rooted in grief, guilt and helplessness, not a considered belief that blood itself is dangerous.
That history also explains Martin’s need for control. He relies on rules, blunt language and clinical certainty because emotion once arrived with an outcome he could not fix. A phobic response threatens the identity he built around being the person who always knows what to do next.
Medical expertise does not erase trauma
The distinction between skill and response is important. Martin can recognize toxic algae behind Cecilia’s alarming condition and act on evidence while other people focus on the novelty of a supposed mermaid. His mind continues doing medical work even when his body has its own limits.
At the same time, the phobia is not harmless merely because it has an explanation. A doctor may encounter blood without warning, and Martin’s patients must be able to trust that their care will continue. The series therefore treats management and honesty as necessary, not optional signs of personal growth.
The public truth changes Martin’s relationships
Going public removes Glendon’s power to reveal the secret as a scandal. It also forces Martin to live without the protection of concealment. Patients and neighbors can now judge him with the full information, while Martin has to demonstrate that disclosure does not make him less capable.
Sarah’s hurt shows the more intimate consequence. She learns about the phobia alongside everyone else and realizes that Martin excluded her from a central part of his life. Repairing that breach requires more than an explanation of Rosemary; it requires Martin to share vulnerability before circumstances force him.
Season 2 turns the phobia from a hidden weakness into a test of how Martin practices medicine and love. Do you think public honesty will help him manage it, or make his work in Port Wenn harder? Tell us below.
