20 Things You Didn’t Know About Spider-Man: Into The Spider-Verse
7. "Just Relax" Sneakily Reveals Gwen Stacy's Identity
When Miles arrives at his new school, he quickly befriends Gwen Stacy (or "Gwanda" as she calls herself). Over time, Miles discovers Gwen is Spider-Woman - a spider-powered superheroine from another universe.
Although Miles was none the wiser of Gwen's origins at first, there's a moment where she nearly lets the cat out of the bag. At one point, Miles' hand gets caught in Gwen's hair, since he's unable to control his newly attained powers. As Miles grows increasingly anxious, Gwen tells him to "just relax". On the first viewing, it sounds like Gwen is giving Miles some simple advice.
But when Miles gets stuck to a ceiling later on, Peter B. Parker tells him to "just relax" to control his powers. Although viewers learn Spider-Woman and Peter have been working together later on, observant viewers would've known this already, if they picked up on the pair's phrasing while helping Miles.
