After a chaotic and emotional weekend that shifted dynamics between Simone (Milly Alcock), Devon (Meghann Fahy) and Michaela (Julianne Moore), "Sirens" closed out its finale with a twist ending that didn't see the sisters reunite after all.

Showrunner Molly Smith Metzler, director Nicole Kassell, stars Fahy and Alcock stand by the Netflix series’ unexpected finale: “I hope this is a debate people are having.”

The addictive show fully filled a White Lotus shaped hole in our hearts—complete with a shocking twist. Spoilers ahead so turn back now if you haven't watched, but Sirens ends with a recently-fired Simone getting the ultimate revenge on Michaela by essentially stealing her life—taking her place by Peter's side at the Kell's annual gala and shutting the door on her past.
