Something potentially remarkable happened on last night’s episode of The CW’s Supergirl. A fairly direct reference to Batman was made, and that’s a big deal. Many moons ago, when Smallville was the big DC TV show, it became common knowledge that Warner Bros didn’t want Batman to appear on the show in any way. The prevailing thought was that having him on a TV show would cheapen him and take away from his movie prospects.

But a lot has changed since those days.

For starters, there’s now a Gotham TV show that shows a young, non-Batman Bruce Wayne. Then there’s the matter that the DC TV landscape has exploded in recent years to include Supergirl, The Flash, Arrow, the Legends of Tomorrow, and- most notably- Superman. Having the Last Son of Krypton, arguably one of the most popular superheroes in the world, featured prominently in this season of Supergirl signifies that Warner Bros has become more open-minded about having its heavy-hitters appear on the small screen.

Last night, Kara, aka Supergirl, said, “My cousin worked with a vigilante once. Tons of gadgets, lots of demons. Vigilantes are nuts!” This is a fairly obvious allusion to Superman working with Batman. 

This could be nothing, or it could be everything. There have been coy little references to the Bat Universe in other DC shows before, but now that we’re officially in a “post-Superman on Supergirl” world, this reference could mean that the door is officially open for The Dark Knight to get in on the fun.

What do you think? We’re now in a world with two versions of Superman (Henry Cavill and Tyler Hoechlin), two versions of The Flash (Grant Gustin and Ezra Miller), two Alfreds (Jeremy Irons and Sean Pertwee), and two Jim Gordons (Ben McKenzie and J.K. Simmons). Is the world ready to have two versions of Batman (Ben Affleck and ???)? Or was this reference on Supergirl just a throwaway easter egg for DC fans? Discuss!
