2) What Is The Flash Talking About?
Straight after the Knightmare sequence, Bruce is visited by someone we know to be The Flash, who gives him a mysterious message before disappearing again.
So, what exactly is the Flash warning Bruce about? Well, it can be assumed that he probably hails from the dystopian future that we saw the trenchcoated Batman inhabit in the previous dream sequence. As such, he is probably attempting to warn Bruce that Superman will turn bad, just as he thought. After all, Supes doesn’t look in the best of moods when he unmasks Batman in that dream.
The Flash also mentions that Lois Lane is “the key.” What does he mean by that? Is she the key to saving the future, or the key to what caused the characters to go down this dark(er) path? And, more importantly, does this mean that Amy Adams will get more to do next time rather than just being saved by Henry Cavill?
