What might happen on Common Side Effects Season 1 finale?

The Season 1 finale promises to provide a dramatic conclusion to the complex story. Tensions are running at an all-time high after the events of Episode 9.

Marshall's discovery that the Blue Angel Mushroom is not as miraculous as initially thought provides the setup for a climactic showdown. Commercialization of the mushroom has led to disastrous effects in the form of hallucinations and chaos in society, which Marshall and Hildy struggle with.

In the meantime, Frances and Rick's efforts to synthesize the mushroom into pills have not only gone awry but also hindered their plans. As Copano and Harrington track Marshall's location in the mushroom farm, Harrington joins Cecily in planning a raid, hinting that law enforcement will take center stage in the finale.

Jonas's terminal illness puts pressure on his search for the mushroom, but his inability to acquire it suggests unresolved tragedy. With Hildy's betrayal 9 causing Marshall's death, there could be repercussions from this turn of events.

The season finale will most likely look into greed, morality, and the repercussions of scientific discovery, and an explosive conclusion to the season is promised while leaving some possible future storylines open.
