This review contains spoilers for Legion’s Season 2 finale, titled “Chapter 19.”
A delusion begins like any other idea, as an egg. That egg was laid in the first season of Legion, and tonight, we saw it hatch.
The eleventh and final episode of Legion’s second season picks up with David and Farouk on a collision course. Farouk finally has his body back. David is unshackled, unhinged and ready for vengeance.
Music and sound have been a prominent motif in this season, and the pair’s beyond bizarre entrances to the tune of “Behind Blue Eyes” somehow feel like an appropriate capstone to it all (it’s worth noting that Lenny’s new blue eyes were a major catalyst for David’s rapid unraveling).
