The Flash, Earth-2

CW

The Flash sees you, DC Comics fans. It sees you and it loves you, and it packed approximately 1,000 references into the super-fun "Welcome to Earth-2" that it knows you will appreciate. (Okay, maybe not a full 1,000, but a lot.)

In fact, the writers could've easily packed in approximately 1,000 more winks and nods than they actually did. "We had a giant board of probably 50 ideas and we had to just whittle them down to the bare bones," executive producer Aaron Helbing reveals. And no, you won't get to find out what they couldn't fit, says EP Todd Helbing. "We would tell you, but they'll probably end up in other episodes!"

The Flash has always been incredibly accessible for people who haven't read the comics and longtime readers alike, so if you are comics-ignorant, you still probably LOVED the bizarro world in which Barry (Grant Gustin) and Cisco (Carlos Valdes) found themselves. In fact, there were also plenty of throwbacks for fans of the show to appreciate.

In no particular order, here are some of our favorite Easter Eggs:

The Flash, Earth-2

CW

-As Barry and co. ran through the breach, they saw clips of other DC heroes—Stephen Amell's Oliver Queen, Melissa Benoist's Supergirl, John Wesley Shipp's version of The Flash (extra meta, since he plays Barry's dad on the show)—and new villain Jonah Hex, who's heading to Legends of Tomorrow soon

-Welcome to Earth-2's Central City, where Leonard Snart is the mayor and the fashion of the day is a very art deco, jazz-age vibe

-Did you catch who Dr. Wells' lab assistant is on Earth-2? None other than Henry Hewitt (Demore Barnes), a.k.a. the first guy they approached to become the second half of Firestorm when went way evil and tried to kill Caitlin

-All hail Earth-2's Det. West, Iris—wife of Barry Allen (OMG) and partner of Floyd "Deadshot" Lawton (Arrow guest star Michael Rowe)

-Speed dial on the phone at the West-Allen household includes Barry's parents (alive and still together in this world), Eddie (RIP), Bruce (Wayne! Hi Batman!), Hal (hey there, Green Lantern), and Diana (Wonder Woman, hello!)

-Killer Frost and Deathstorm aren't the only villainous versions of our beloved S.T.A.R. Labs team members to appear: Enter Reverb, a.k.a. the super-cool and SUPER EVIL version of Cisco who is into man-ponytails and leather

There were probably plenty more, too, but those are the ones we caught as we watched the episode through the first time. Got an eagle eye? Let us know what Easter Eggs we missed (there are surely several) in the comments below!
