The latest confirmation from Snyder has to do with the Flash in Batman v Superman and the Knightmare Timeline, letting fans know that they are on the right track in a pretty cryptic social media post that took some deciphering from fans.
The Flash from the Knightmare Timeline saw Superman “die” after he lost sense of who he was, according to Zack Snyder.
Zack Snyder continues his quest to explain every one of his decisions in Batman v Superman, much like Rian Johnson and The Last Jedi.
In Batman v Superman, Ezra Miller’s Flash character makes a cameo to warn Bruce Wayne of the future after the “Knightmare sequence.”
