After keeping the secret for over a year, Sadie Sink's Marvel character is spoiled at the Spider-Man

Theory Briefing

• Sink kept her Marvel character secret for more than a year before a Spider-Man event reportedly spoiled it.
• The leak triggered a wave of fan speculation, with Jean Grey emerging as the leading theory for her role.
• Jean Grey's history as a world-altering X-Men figure would make the casting a major signal about Marvel's mutant plans.
• No official confirmation has been made, meaning the Jean Grey theory remains fan-driven rather than studio-confirmed.
