>>114767657Geoff Johns talked about this once. The whole Trinity War before editorial changed things wasn't supposed to just be a war between the three different JL books, but a war between the trinity characters. Johns wanted to set-up this messy love relationship between Superman, Batman, and Wonder Woman where they'd all cuck each other, and also Steve Trevor and Catwoman somewhere in that mix too. So they'd all fight about who dicked who. Superman would get angry about Batman dicking Wonder Woman, Batman would be angry about Trevor dicking Catwoman, Trevor would remain angry about Superman dicking Wonder Woman, Wonder Woman would be angry about Catwoman sucking Trevor, Catwoman would be angry about Wonder Woman strap-oning Batman, and so on. And this fight would endanger the whole world.
You can sorta see the seeds being laid here and there, before editorial put a brake on things.
