10 DCEU Mysteries That Are Yet To Be Solved
6. How Is Lois Lane 'The Key'?
This entire list could be made up of entries relating to Batman's Dawn of Justice Knightmare sequences, particularly the one featuring a time-jumping Flash.
One line which Barry Allen speaks, in particular, hints at a major plot point for the DC Extended Universe going forward."Bruce! Listen to me right now! It’s Lois! Lois Lane! She’s the key," the Scarlet Speedster pleads.
Precisely how Lois is "the key" has sparked a healthy amount of fan debate online, but those familiar with the DC comic books will know there's a strong chance this is alluding to an Injustice: Gods Among Us-style event.
It seems feasible there are two potential futures for the DCEU: one where MS Lane dies and Supes goes bad, and one where she lives and he remains a righteous hero.
Obviously, The Flash delivered his warning from a post-apocalyptic future so the former reality could be averted, but the how of this scenario as well as its many finer details needs to be cleared up in Justice League.
