I know that Bats/Wondy only really works in dcaulike circumstances so ymmv BUT dig if you will a picture:
The Justice League is in session and Superman is like “Batman! You’re up for a secret mission or something!!” (He calls him Batman bc Bruce doesn’t let anyone know his secret identity bc he’s got a lot of trust issues. Poor lonely handsome Sung Kang Batman.)
And Wonder Woman is like kinda into Batman and his trust issues.
(Pretend he’s scowling here.)
And so Wonder Woman offers to drive Batman to his destination in her invisible jet and Batman is like ‘oh shit’ bc if anyone can break down his defenses it’s Diana of Themyscira: Dreamboat and Asskicker.
And Superman is momentarily taken aback by the unexpected romantic tension!
But then he starts thinking of how happy his friends would be if they found love with each other ~~
WOW SOMEBODY PAY ME
