Theme

A few minutes into the film, Tony Stark records a message for Pepper Potts in which he states “I know I said no more surprises. But I was hoping to pull off one LAST one”. This statement works as the theme of the movie as the Avengers are at their wits’ end and will make one last attempt to undo everything Thanos has done. Furthermore, this is also the final chapter in the Infinity Saga.

Banner can now transform into the Hulk and still retain control over himself. However, like Tony, he too is skeptical about the plan.

Later on, Tony finds a picture of him and Peter Parker. This motivates him to test the time travel theory, which he ends up cracking.
