After months of speculation ahead of the release of Spider-Man: Brand New Day, fans finally have confirmation that Sadie Sink is the Marvel Cinematic Universe's Jean Grey. Some moviegoers kept quiet about it to avoid spoiling the news, but Marvel fully revealed Sink and the rest of the current X-Men cast during the D23 expo. To capitalize on the MCU buzz, Marvel Comics has announced that Jean Grey will get a new limited series before the end of the year.
