Everything You Need to Know For Tonight's 'Legion' Season 3 Return

Legion returns for its third and final season tonight, Monday, June 24 at 10:00 PM ET/PT on FX. Get ready to go back to the end.

Based on the Marvel Comics by Chris Claremont and Bill Sienkiewicz, Legion is the story of “David Haller” (Dan Stevens), a man who believed himself to be schizophrenic only to discover that he is the most powerful mutant the world has ever seen.

From childhood, David shuffled from one psychiatric institution to the next until, in his early 30s, he met and fell in love with a beautiful and troubled fellow patient named “Syd Barrett” (Rachel Keller). After Syd and David shared a startling encounter, he was forced to confront the shocking reality that the voices he hears and the visions he sees are actually real. With the help of Syd and a team of specialists who also possess unique and extraordinary gifts – “Ptonomy Wallace” (Jeremie Harris), “Kerry Loudermilk” (Amber Midthunder) and “Cary Loudermilk” (Bill Irwin) – David unlocked a deeply suppressed truth: he had been haunted his entire life by a malicious parasite of unimaginable power. Known as “The Shadow King,” this malevolent creature appeared in the form of David’s friend “Lenny Busker” (Aubrey Plaza), but was actually an ancient being named “Amahl Farouk” (Navid Negahban).

During an epic showdown, David managed to push Farouk out of his body and gain control of his mind. With Farouk on the loose, the team formed an unlikely alliance with their former enemy, “Clark DeBussy” (Hamish Linklater), and his well-funded government organization, Division 3. Unfortunately, the hunt for Farouk reawakened the dark voices in David’s head, and with them, a lust for power. At odds with everyone he once considered a friend, David enlists the help of a young mutant named “Switch” (Lauren Tsai) whose secret ability is key to his plans to repair the damaged he caused.

How did we get here? Do you remember? Let us help you. Here's a refresher on where we left off with everyone from David, Syd, Farouk, Lenny, and Summerland/Division 3.

The cast and creatives behind the series teased what's to come in the final chapter.

David Haller wants to take your pain away so he created a commune for his acolytes who show him unconditional love.

To understand David Haller, one must understand his parentage. Charles Xavier and Gabrielle's love story parallels that of David and Syd's.

Meanwhile all of David's former friends and allies team up with Amahl Farouk to stop him.

But can Farouk be trusted?

There’s no time like the present. Or the past. Or the future. The final season of Legion premieres tonight on FX! When you are ready, find us.
