One of Us Is Lying Season 2 is here. You’ve probably binged your way through the series by now. If not, what are you doing reading this? We’re going into some major spoilers for the end of the season.

In the final episode of One of Us Is Lying Season 2, we found out who Simon Says was. This was a series where nobody could be trusted, especially not the new people in town. But also, it turned out that Jake had some secrets of his own.

Jake didn’t go to Greece that summer. He was in rehab, where he met a couple of girls who fell for him. One of those was Nate’s tutor, Fiona. It turned out that Fiona wasn’t as innocent as she seemed to be. She was so in love with Jake that she was willing to torture Murder Club for his death. Yes, she was the one in the bear costume at Halloween night.

Fiona was Simons Says in One of Us Is Lying Season 2

Once Bronwyn found the photo of Fiona at the rehab center, the pieces of the puzzle were put together. It turned out that Jake made sure Simon died in retaliation for Simon sharing details of what Fiona had done to put her in rehab and force her to change schools. Fiona didn’t know that Jake was the one to tell Simon, though. Even up to her arrest, she refused to believe it.

Fiona wasn’t working alone, though. When Maeve realized Bronwyn’s plan to frame Fiona for the murder of Simon wasn’t going to work, Maeve decided to trick Fiona into working together. She made Fiona believe that she also wanted revenge.

That has led to Murder Club no longer trusting her. Maeve and Janae are no longer together, but Maeve’s plan did work. She managed to get Fiona’s prints on the gun that killed Jake. Fiona was also later caught in the act of trying to kill Bronwyn.

What happened to Fiona in the finale?

However, there’s a new mystery to solve. While in prison, Fiona was given a cup of water. As she drank it, she started coughing. The water had been poisoned with something.

Fiona was left dead on the floor of her prison cell at the end of One of Us Is Lying Season 2. Who would want her dead?
