The anticipation for Spider-Man 4 continues to build, and with it comes a flurry of speculation about who might join Tom Holland’s Peter Parker in his next adventure. One of the latest reports claims that Stranger Things star Sadie Sink has been cast in the film, a move that has excited fans eager to see the talented actress join the Marvel Cinematic Universe. While many assume she’d play a classic love interest like Mary Jane Watson or a new take on Gwen Stacy, one fan theory suggests her character could be someone far more unexpected—adding an entirely new layer to the upcoming film’s potential storyline.
