Episode 7 of Watson marks a turning point in the series. Up until now, the show has balanced medical cases with an underlying web of intrigue. But in this episode, everything intensifies. The pressure is on, the stakes are high, and the characters are backed into impossible situations.
At the heart of this episode is Shinwell (Ritchie Coster), a man caught between duty and survival. In Episode 3, he was ordered to switch Dr. Watson’s (Morris Chestnut) medication under Moriarty’s (Randall Park) instructions. If he refused, his pseudo-parents back in England would pay the price. Shinwell made his choice—he did not swap the pills. Now, that decision has deadly consequences.
As the episode begins, Shinwell receives a chilling message: a floral arrangement, photographs of his sleeping relatives, and a clear threat. The message is simple—he must switch the pills, or his loved ones will die. The realization sinks in: there is no way out of this. Or so he thinks.

An Unforgiving Dilemma
Shinwell knows he has no choice. His hands shake as he sneaks into Watson’s office, preparing to make the switch. But before he can, someone walks in—Ginny (Jan Kamar), the episode’s patient-of-the-week.
Ginny suffers from episodic amnesia, which means she forgets things within minutes. This could work in Shinwell’s favor. She sees him, but before she can fully process what he’s doing, she forgets. But there’s a problem. Ginny has a habit of writing things down. Before her memory resets, she quickly jots down what she saw in her planner.
This single moment changes everything. Later, Watson finds the note and starts questioning what is happening with his medication. But that’s not the only sign that something is wrong.
Watson’s Hallucinations and the Ghost of Sherlock Holmes
Throughout the episode, Watson begins to experience unsettling auditory hallucinations. He hears violin music—music that Sherlock Holmes used to play. He hears cryptic words of wisdom, as if Holmes himself is whispering from beyond the grave. The hallucinations feel real, but Watson knows they can’t be.
At first, he brushes them off as exhaustion. But as they continue, he begins to wonder—are they a symptom of something more? Is there something wrong with his medication? Or is his subconscious trying to warn him?
As Watson digs deeper, Shinwell grows increasingly nervous. He can tell Watson is onto something. The fear in his eyes is clear—he knows his time is running out.
A Medical Mystery Unlike Any Other
While Watson wrestles with his own crisis, a new mystery unfolds—Ginny’s terrifying illness.
She first arrives at the ER with a deep gash on her stomach, claiming that something is inside her. The nurses believe she is hallucinating. They assume she is having a psychotic episode and try to admit her to the psychiatric ward. But Ginny panics. She runs from the ER, jumps into an elevator, and stumbles into Watson’s clinic.
Watson immediately sees that something isn’t right. Ginny’s symptoms are strange, and her fear seems genuine. Instead of dismissing her, he decides to take her case.
Piecing Together the Clues
Watson and his team begin investigating. They learn that Ginny recently traveled to Machu Picchu, which raises concerns about potential infections. They consider whether she may have been exposed to Ayahuasca, a hallucinogenic plant used in traditional medicine. Could her symptoms be the result of a bad reaction? Or is there something else going on?
Ginny insists, again and again, that something is inside her. She is terrified, convinced that she is being eaten alive. Watson struggles to make sense of her claims. Is this paranoia, or is there a real medical explanation?
As Ginny’s condition worsens, Watson turns to his hallucinations for answers. In a strange way, the voice of Sherlock Holmes leads him to the truth.
The Shocking Discovery
After running a series of tests, Watson finally uncovers the horrifying answer. Ginny isn’t imagining things. She is not hallucinating. She really is being eaten alive.
During her trip, she was unknowingly infected by a rare parasite. The creature had been slowly growing inside her, feeding off her organs. Her amnesia was not a psychological condition—it was a symptom of the parasite’s effect on her nervous system.
The revelation is shocking. The team rushes to perform emergency surgery, removing the parasite just in time. Ginny’s life is saved, and Watson’s instincts prove right once again.
The End of the Road for Shinwell?
As Watson solves Ginny’s case, Shinwell’s situation grows worse. Watson continues to investigate his medication, and it’s only a matter of time before he uncovers the truth.
Shinwell realizes he is trapped. If he follows Moriarty’s orders, Watson’s health could be at risk. If he refuses, his loved ones could die. The pressure is unbearable.
But then, a final twist changes everything. Shinwell reaches out to his handlers, expressing his concerns. Their response is chilling. They tell him to trust his partners. This cryptic message suggests that he may not be as alone as he thinks. But before he can figure out what it means, something horrifying happens.

The episode ends with a gruesome scene—teeth marks, blood, and the brutal consequences of the choices that have been made. The full impact of Shinwell’s actions will come to light in the next episode.
Final Thoughts
This episode of Watson delivers a perfect mix of tension, mystery, and psychological drama. The hallucinations add a supernatural touch, while the medical case keeps the intrigue alive. The stakes have never been higher, and the show is finally delivering on its most intense and emotional moments.
With Shinwell backed into a corner and Watson uncovering more secrets, the next episode promises even bigger revelations.
What happens next? Only time will tell—but one thing is clear: Watson is finally hitting its stride.
