That BATMAN V SUPERMAN Dream Sequence May Not Mean What We All Thought

Spoilers ahead.

One of Batman v Superman: Dawn of Justice's most talked-about sections is the part in which we see Batman's "Knightmare" and The Flash's inter-dimensional warning to him. Both seem to be set up as dream sequences, and director Zack Snyder has since said that the Knightmare portion could be a look into one possible future.

But while The Flash sequence that immediately follows would be completely incomprehensible to general audiences, fans could probably deduce that the speedster was traveling through a boom tube in order to give Bruce Wayne a warning. (A warning he does not heed and doesn't tell a soul about, but that's neither here nor there.) He says something about how "you were right about him" and to "find us," presumably meaning the other members of the Justice League. I, like everyone else I know who saw the movie, thought that The Flash was referring to Superman in this scene, especially since it came on the heels of a nightmarish possible-future sequence in which Superman is even more full of rage than normal. But according to Jay Olivia, the storyboard artist who worked with Snyder on this scene, when The Flash says "you were right about him," he may have been referring to someone else entirely.

From the Hall of Justice podcast (via Uproxx and Screen Rant):

“Okay…you’ve watched The Flashpoint Paradox, my movie, right? In the DC Universe in the comics, [..] when you go back in time you create this kind of ‘Time Boom’ kind of thing where lots of things change. […] I don’t know if this is Zack’s thinking, but this is mine: What if that isn’t a dream sequence? What if what you saw was a Time Boom, a latent memory from the future when Flash comes back? If you look at the cut, he doesn’t go to sleep! He’s waiting for the [Lexcorp file decryption] and suddenly this [Knightmare sequence] comes in, and he’s jogged out of it seeing his own death. And what does he see? He sees Flash. And if you’re a DC fan, you know what’s happening. You know that Flash going back in time, that memory is now coming back to him… mind you, it’s jumbled.”

“And remember, when Flash goes back in time, he tells him ‘you were right about him.’ He doesn’t say exactly who ‘him’ is. The average audience member, and even Bruce Wayne, is going to think that he’s right about Superman, when in fact he’s referring to someone else.”

So...who do you think The Flash was talking about in that scene? And does anyone have any theories about why Bruce doesn't say anything about this to anyone?
