There’s been a lot of speculation about who “Pit Girl” is in Yellowjackets, and the most convincing theory explains Misty’s disturbing behavior during the show’s premiere. Yellowjackets season 1 kicks off with a terrified girl running through the woods, and it’s soon revealed that the other girls are hunting her. The identity of this character remains a mystery, but she’s become widely known as “Pit Girl.” And with people gradually dying in the show’s past storyline, it’s only a matter of time until we learn who is killed and eaten in Yellowjackets’ opening scene.
