Warning: this article contains full spoilers for Batman #50!
Tear down the garlands and put away the confetti, Batman #50 has made it official: there won’t be a Batman and Catwoman wedding after all. Emotions are, justifiably, running high but the truth is? The lack of actual matrimony taking place in the extra-sized wedding special isn’t as dire or as damning as it may seem. In fact, the actual wedding part of the wedding special was the least important part of the story. The critical component of “Batrimony” has always been the journey rather than the destination.
