WARNING: This article contains spoilers from Yellowjackets.
Yellowjackets season three is set to feature Oscar-winner Hilary Swank, yet Showtime has kept details about her role under wraps.
Anticipation is high as fans eagerly await the fallout from the cabin fire in the teen timeline and Natalie’s (Juliette Lewis) accidental death at the hands of Misty (Christina Ricci) in the adult storyline.
As the thriller gears up for its return on Showtime and Paramount+, it was revealed that the Boys Don’t Cry and Million Dollar Baby star will be a recurring guest in the new season.
Swank makes a brief appearance in the latest trailer, looking battered and shocked, standing in a road and exclaiming “holy s***” before dashing away.
Speculation suggests she’ll be part of the adult timeline, but her exact role remains a mystery.
Fans on Reddit have been buzzing with theories, some guessing she might portray a law enforcement officer investigating the eerie plane crash, while others suggest she could be playing Coach Ben Scott’s (Steven Krueger) sister.
There’s also a camp betting on Swank being another survivor, possibly the grown-up Melissa (Jenna Burgess), citing physical resemblances between the two actresses.
A new speculation about the hit series has surfaced, suggesting that the award-winning actress might play not Melissa, but her sister.
A fan hypothesized on Reddit: “Maybe Hilary Swank is playing Melissa’s twin sister.
“Twins have a strong bond. Sometimes even a psychic connection. Maybe Melissa had a twin who could feel and sense what happened in the wilderness.
“She wants revenge for losing her twin. And knows on a very deep connected twin level that the survivors ate her twin. I am a twin so reading this thread gave me the idea.”
Another user was intrigued by this notion, commenting: “That’s spooky…I like your thinking though. We’ve never heard if any YJs had siblings…opens up a lot of possibilities.”
Since its premiere four years ago, Yellowjackets has often been linked to Greek mythology, with fans noting that the name Melissa means “honey bee”, with the Princess of Crete turning into a bee after learning how to collect honey.
It’s conjectured that Melissa will be key in locating food for the girls’ survival in winter.
Reacting to the twin theory, another user added: “I’m big on the ‘Melissa will do bee s*** like her Greek Mythology nymphs twin’ but also want to bring up that Melissa the Greek Bee Nymph has a twin.
“According to Greek mythology, Melissa had a twin sister named Amalthea, and both were nymphs who fed infant Zeus goats’ milk.”
The original writer responded: “Oh s*** that’s wild. Interesting. Thanks for sharing that info. Maybe my twin theory could be true. We shall see.”
This raises the question: could the Yellowjackets fan be correct in predicting Hilary Swank will play Melissa’s sister, and if so, how will she fit into the 2025 timeline?
Yellowjackets season three premieres on Friday, February 14, on Paramount+ and Showtime.
