Perhaps the most pleasurable thing about The Flash is the way it has been delightfully unafraid of showcasing the weirdest and silliest aspects of its title character. Throughout the initially bumpy but overall brilliant first season, Barry Allen has traveled through time, ran through worm holes and even threw down with an evil psychic gorilla. It may not be the perfect Flash show, but it’s far better than I ever could have hoped.

And now there’s this latest promo, where Barry meets his Earth-2 counterpart, Jay Garrick, the superhero that your dad could probably cosplay. This isn’t exactly surprising; Jay’s distinctive helmet made a super conspicuous cameo in season one’s finale and sharp-eyed viewers may also have spotted a figure on the Central City Police Department’s mural that bears a striking resemblance to him. Once Flash made it clear (from the very first episode, no less) that it wasn’t going to shy away from the time travel and alternate universe stuff, I expected Jay to show up at some point in the series.

So who is Jay Garrick? Simply put, he is the original Flash, having first appeared in Flash Comics #1 all the way back in 1940. Created by Gardner Fox and Harry Lampert, Garrick was a key member of DC Comics’ Golden Age lineup and was also part of the Justice Society of America, the first ever superhero team both in real life and in DC Universe continuity. Jay’s solo series was cancelled in 1948 and DC rebooted the Flash eight years later in the form of Barry Allen. The two Flashes famously teamed up in The Flash #123 (September 1961) by Fox and Carmine Infantino. More so than the team up itself, that story is best remembered for introducing the concept of multiverse to DC Comics, which is where things get interesting…

Will Earth-2 (Jay’s native world) appear in The Flash’s second season? Will we be introduced to the multiverse? Hell, is the freaking JSA going to show up? That I’m asking all of these questions should indicate to you that I’m yearning for Flash to come back on the air almost as much as Star Wars: Rebels. To my knowledge, no live action DC movie project has ever tried to take a crack at the dense and endlessly confusing multiverse. It may have come up in Smallville at some point during its decade run but that would require me to actually watch Smallville, which is a fate I wouldn’t wish upon anyone except for maybe these people.

The Flash season two will premiere on Oct. 6 on The CW.
