An Avengers: Endgame deleted scene could prove that a popular theory about the villain Thanos (Josh Brolin) has been true all along.
Avengers: Endgame is available to stream on Disney Plus.
Avengers: Endgame ended with Tony Stark snapping his fingers and wiping out Thanos and his army, much in the same way that Thanos wiped out half of the Avengers.
If all those who were willed out of existence by Thanos can return in the Marvel Cinematic Universe, then surely Thanos can, too.
