Throughout No Way Home, the three Spider-Men engage in some pretty hilarious small talk involving their web-shooters, the Avengers, and more. At one point before the big battle scene, Maguire's Peter tells the other Spider-Men his back is stiff, and that's when Garfield's Peter lifts him and cracks his back, offering him some much-needed relief. The scene seems to reference the time when Peter hurts his back in Spider-Man 2 after he falls off a building and gets up while saying "my back" repeatedly. Of course, it could also allude to rumors Gyllenhaal was meant to replace Maguire in Spider-Man 2 after Maguire injured his back in real life.
