A recent development in the ongoing saga of the upcoming Spider-Man film, titled "Brand New Day," has ignited fresh speculations regarding a pivotal character's story arc. A leaked report, attributed to the insider account @MyTimeToShineHello on X (formerly Twitter), has revealed the cast member who may have been involved in an on-set arrest scene. The disclosure sheds light on a potential game-changer in the Marvel movie's narrative.

According to the insider's post on November 24, 2025, "I can confirm that the character being arrested on set is Sadie's. She is dangerous." This revelation aligns with the ongoing rumors of Sadie Sink filming a secret role in London for Marvel Studios' upcoming production. Photographers have captured her on set, dressed in full-body puffer gear to conceal her costume, further fueling the mystery surrounding her character.
Sink's recent interview with Entertainment Weekly adds an intriguing layer to the story. She quipped, "Tom can wave at the fans because people know who he is, but then you get a glimpse of me and I’m like a penguin." The studio's meticulous secrecy efforts suggest that her character holds a crucial role in the storyline.
Fan speculation has linked Sink to various Marvel characters, including Jean Grey and Rachel Cole-Alves. In the same EW interview, Sink addressed these rumors, stating, "That was happening before I even knew that I would be working on this project. I was like, 'Wait! What are people talking about?'" She concluded with a hint of excitement, "People will just have to wait and see. I’m excited for all of it to maybe be put to rest."
Sink's journey with Marvel began while filming Stranger Things Season 5. She revealed that discussions about her role did not commence far in advance, saying, "Not as far back as you would think." As speculation swirls around her role and potential arrest scene, fans eagerly await official details from Marvel about the character she portrays in Spider-Man: Brand New Day.
