In case you didn't read the headline closely: Spoilers for "Spider-Man: Brand New Day" follow. Several days ago at the "Spider-Man: Brand New Day" premiere, singer Steve Lacy was interviewed on the red carpet. Lacy didn't seem to register the deer-in-headlights look on the face of the woman interviewing him, who had asked Lacy to answer "without spoiling anything." Instead, Lacy didn't seem to realize that he was committing a gaffe in his response. The presence of Jean Grey (Sadie Sink) and her antagonistic role in "Brand New Day" shouldn't be treated as a secret.
