Many Marvel Cinematic Universe fans let out a collective groan when Doctor Strange summoned the Time Stone and handed it over to Thanos towards the end of Infinity War.
It appears that Thanos may have been wrong about Doctor Strange in Avengers: Infinity War.
Since the Time Stone can travel back and forth through time, the theory states that the Time Stone will arrive back on Titan and into Tony Stark’s hands.
If any of this Infinity War theory is true, it could explain how Ant-Man is able to escape the Quantum Realm.
