The Flash has a literal world of work ahead of it for next week’s “Earth-2” conclusion to live up to the easter egg-filled premiere, and plenty more DC goodness ahead. Not only does a new full-length trailer tease the Arrow crossover of King Shark’s return, but so too do we finally get a peek under the mask of big bad Zoom.

The CW released a brand-new trailer upcoming episodes of The Flash, including the second half of our alternate-universe adventure “Escape from Earth-2,” as well as the following week’s return of King Shark. And while “The Reverse-Flash Returns” dropped a huge clue to Zoom’s identity, an upcoming episode may reveal it outright.

In the meantime, so reads the full synopsis for Tuesday’s “Escape From Earth-2”:

On Earth-2, the team races to find Zoom’s lair and asks for help from the most unexpected source. Meanwhile, back on Earth-1, Caitlin (Danielle Panabaker) rushes to perfect Velocity-9 so that Jay (guest star Teddy Sears) can stop the Geomancer (guest star Adam Stafford).

We’ll bring the latest on The Flash and Earth-2, but who might Zoom finally turn out to be? Henry? Hunter Zolomon? Jay?
