On Vero recently, a user named Nick Albright posted his theory that the recently revealed deleted scene from Justice League was meant to thematically harken back to Man of Steel.
This is the deleted scene Albright is referencing:
It features a freshly resurrected Kal-El/Clark Kent/Superman walking through the Kryptonian ship and coming upon a black version of his suit. He glances at it but turns away to face something else: his old suit, which he then puts on.
His tweet compiles his theory and Snyder’s response and you can check it out below:
Albright’s theory essentially explains how he sees the scene in Justice League as a “callback” to the Man of Steel line:
All these changes that you’re going through, one day… one day you’re gonna think of them as a blessing; and when that day comes, you’re gonna have to make a choice… a choice of whether to stand proud in front of the human race or not.
Clark is being tempted by the suit and going to the dark, but instead chooses the light.
Snyder then responded on Vero and confirmed Albright’s theory, adding the idea of Clark being born again (once on Krypton and now on Earth).
