Even before its release, the casting of "Stranger Things" star Sadie Sink in "Spider-Man: Brand New Day" has become one of the hottest mysteries among Marvel fans.
Speculation has been rampant regarding her role, with theories ranging from Peter Parker's daughter Mayday Parker and Gwen Stacy to the multiversal shapeshifter Shathra. However, the latest wave of discussion points back to a more significant name: Jean Grey.
Before Sadie Sink joined "Spider-Man: Brand New Day," industry buzz suggested she was a top contender to play Jean Grey in Marvel's upcoming "X-Men" reboot. While her inclusion in the new Spider-Man film initially muddled expectations, outlets like Deadline have kept the possibility alive, suggesting she might still appear as a mutant in the film.
While introducing an X-Men character for the first time in a "Spider-Man" movie might seem unexpected, such an arrangement would make perfect sense if Marvel aims to lay the groundwork for the new X-Men universe early. The confirmed mutant characters in "Avengers: Endgame" are still from the Fox era, which means new versions of these characters will require a fresh introduction.
Adding to the speculation, YouTuber Josh from "Den of Nerds" firmly stated that the initial rumors were not mistaken. He revealed that Marvel has gone to great lengths to conceal Sadie Sink's role, noting that "they have this thing locked down tight," implying her true identity might be more significant than anticipated.
Another report suggests Sink might initially appear under a false identity, only for a major twist to reveal her true role later in the film, a narrative approach consistent with Marvel's recent penchant for disguised characters.
Regardless of who she plays, it's confirmed that Sadie Sink's character will continue to appear in "Avengers: Secret Wars," further solidifying the belief that her role holds long-term significance within the MCU and is far from a mere supporting part.
