Marienne's storyline in You Season 4 is intense and complex. Here's what happened to her:
- Marienne initially escapes Joe and flees to Paris with her daughter Juliette after discovering Joe's dark deeds, including killing her ex-husband Ryan and faking his own death. She tries to live safely away from him
- Joe tracks her down in London and, in a dissociative state, kidnaps her and imprisons her in a cage for several weeks without food or drink. Marienne endures this captivity alone, fighting to survive and protect her daughter in her thoughts
- With the help of Nadia, who finds Marienne and tries to help her, Marienne eventually escapes Joe's captivity. Nadia even fakes Marienne's death by substituting beta-blockers to mimic an overdose, making it appear Marienne died from pills, but Marienne never actually dies
- After Joe abandons her body, Nadia revives Marienne with a stimulant injection. Marienne then returns to Paris to live openly as an artist and be with her daughter Juliette
- Marienne also plays a key role in turning Joe's current partner Bronte against him by sharing her experience, which contributes to Joe's eventual arrest
In summary, Marienne survives Joe's kidnapping and faked death, escapes his control, and ends the season free in Paris, focused on her daughter and seeking justice rather than revenge
