The Question: The Flash's message to Bruce warns him that Lois is the key to everything, presumably in reference to future events in Justice League, but what exactly does he mean? The Likely Answer: If we accept the possibility that Justice League may be about Darkseid corrupting Superman as is hinted at in the Knightmare scene, then perhaps it is Lois who can restore his humanity. Hopefully it won't end up being something as cheesy as "the power of love conquers all", and more interesting, maybe it will require her death amid all the mayhem to finally snap Superman out of it. As long as it's not some limp, inconsequential of piece plotting that makes Lois feel totally redundant, then it's all good.
