Spider-Man 4 Rumor Reveals Key Plot for Sadie Sink’s ‘Dangerous’ Character

A recent update from the set of Spider-Man: Brand New Day has sparked new speculation about a key character’s storyline. A report has surfaced revealing which cast member may have been involved in an on-set arrest scene. The information sheds light on a potentially pivotal moment in the upcoming Marvel film.

Sadie Sink’s character might get arrested in Spider-Man 4

Sadie Sink’s character may be involved in a major plot event in Spider-Man: Brand New Day, according to a post by insider account @MyTimeToShineHello on X (formerly Twitter). “I can confirm that the character being arrested on set is Sadie’s. She is dangerous,” the account stated on November 24, 2025. This aligns with ongoing reports of her filming a secret role in London for the upcoming Marvel Studios production.

Marvel Studios has not confirmed Sink’s role in Spider-Man 4, keeping all character details under wraps. Photographers captured her on set wearing full-body puffer gear to conceal her costume.

Sink recently told Entertainment Weekly, “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 secrecy efforts suggest her character plays a key part in the storyline.

Fan speculation has connected Sink to various Marvel characters, including Jean Grey and Rachel Cole-Alves. Sink addressed the rumors in the same EW interview, clarifying, “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 also added, “People will just have to wait and see. I’m excited for all of it to maybe be put to rest.”

Sink began working with Marvel while filming Stranger Things Season 5. She confirmed that the discussions did not start far in advance, saying, “Not as far back as you would think.” As speculation grows around her role and potential arrest scene, fans await official details from Marvel about the character she portrays in Spider-Man: Brand New Day.
