We Were Liars left Prime Video subscribers distraught in the last few moments of its agonising finale.

WARNING: This article contains spoilers from We Were Liars.

We Were Liars star Caitlin Fitzgerald has addressed fans’ emotional TikTok videos as they film themselves reacting to the drama’s final episode.

Based on author E. Lockhart’s novel of the same name, We Were Liars revolves around the extraordinarily rich Sinclair family who spend their summers at their private island off the coast of Massachusetts.

One summer, Cadence Sinclair (played by Emily Alyn Lind) was involved in an incident that she can remember nothing about and no one will tell her what happened.

But it was the last episode of the Prime Video drama where her world really came crashing down when she discovers that she and her cousins Johnny (Joseph Zada) and Mirren Sinclair (Esther McGregor) and family friend Gat Patil (Shubham Maheshwari) set the mansion on fire.

In a devastating turn of events though, Cadence was the only one who was able to get out in time with Johnny, Mirren and Gat all dying in the blaze.

Throughout the series, Cadence had simply been imagining her friends were by her side, and was beside herself when she realised the truth.

Understandably, subscribers who hadn’t read the book were shocked, with an ongoing TikTok trend of fans filming themselves sobbing at the finale.

When Screen Time spoke to Penny Sinclair star Caitlin Fitzgerald about the reaction on social media, she admitted she wasn’t surprised.

“I always feel like I have to slightly apologise for what we put you through with that show. It’s a rough ride”, Fitzgerald laughs.

“A few years after the book came out during Covid, there was a similar kind of reading the last chapter and filming yourself weeping.

“So I was somewhat prepared for it but we knew because we couldn’t get through the script.”

Fitzgerald continues: “We did a read through of the final episode and all of us were beside ourselves.

“Even David Morrissey who is quite a stoic guy, was just like ‘give me a second’, had to kind of compose himself.

“And we knew what was coming so I can only imagine what it was like the first go around if you didn’t know.”

An official renewal hasn’t been given to We Were Liars just yet but there are talks of a prequel in the works, based on Lockhart’s novel Family of Liars.

So fans are just going to have to wait for now to find out if there will be more on the way from the Sinclair family.

We Were Liars is available to watch on Prime Video.
