The Bat and the Wild Card knowing each other should be a multiversal constant. Whether they're at odds or enemies, just friends or something more, they should interact with each other at least once.
I once saw Waynzel's post and thought of drawing something like it one day and here it is.
"How'd you do it?" How'd you get him to marry you and stay that way?"
"Oh, it's easy. I wasn't a pussy like you".
"..."
Look, I don't have anything against BatCat. It was my first Batship alongside WonderBat but Gotham War really didn't do their relationship any favors. If the failed wedding was bad enough, this arc almost 'Pauled' their relationship. I hope the next writer finds a way to rewrite write the main continuitiy Bruce to not be a black and white viewing self righteous deranged prick and Selina as less of a hypocritical gaslighting crime lord.
I don't hate Selina and Bruce together, I hate the way they're written right now because seeing them bicker like divorced parents rather an old married couple and act out of character ruins the appeal of their relationship.
