The episode saw Copano and Harrington finally discovering Marshall's location from Zane. But they go their separate ways after they fail to decide unanimously how to close in on him.
Elsewhere, Hildy reveals that she let Marshall out of the prison through Amelia's help, and also convinces him to grow mushrooms together, claiming that all their operations would be ethical.
However, Marshall realizes that Hildy is using the mushrooms for her own advantage and charging money from the people. They have a disagreement after which Hildy pushes Marshall off a cliff, a shocking cliffhanger for the finale.
Meanwhile, Harrington gives Cecily Marshall's location information. The episode ends with him joining the FBI and Cecily leading a raid on Marshall's mushroom business.
The Common Side Effects finale, which will be released on March 30, 2025, will finally reveal what happened to Marshall after he fell from the cliff and whether his mushroom business will survive the FBI's raid.
Here is the complete Common Side Effects Episode 9 recap.
Marshall and Hildy disagree over their mushroom business in Common Side Effects Episode 9
Common Side Effects' previous episode saw Marshall reunite with his mentor, Hildy, to work on their idea and grow new mushrooms, unaware of her selfish motives.
The penultimate episode saw the duo finally growing mushrooms together, but they soon got into a disagreement about the said mushrooms' use. While initially Hildy discusses how to put the mushrooms to their proper use, Marshall's reluctance is quickly realised when he learns that she has been charging people for the mushrooms.
Further, Marshall also realises that Jarvis and Rusty are selling their product to young junkies to get high, to make more money. He is disappointed seeing their misuse and tells Hildy that more tests must be done before they can start handing out the mushrooms to the population.
However, Hildy cunningly lures him to a cliff and angrily pushes him off it. While Marshall naturally suffers severe injuries, his fate remains to be seen in the finale.
Rick and Frances set up their own mushroom business in Common Side Effects Episode 9
In the previous episode of Common Side Effects, we learned that Jonas fired Rick from Reutical Pharmaceuticals, Inc., which forced him to team up with Frances and set up their own mushroom business.
While the duo is not able to replicate the original product, they create some products inspired by the original and, after much disagreement, finally agree on the future of their company.
However, things take a turn when Jonas learns about his terminal illness and the fact that he only has a few months to live. While he tries desperately to grow the mushrooms himself and find a cure for his illness, he fails. As a last resort, he calls Rick for some mushrooms he grew with Frances, who does not respond to his calls.
