Barry (Grant Gustin) and Co. will take a trip to Harry's (Tom Cavanagh) home universe this spring, and fans should expect our heroes' doppelgangers to be markedly different than the STAR Labs team we've come to know and love.

"Some of these people are beyond different," executive producer Andrew Kreisberg told Entertainment Weekly. "There are a couple of surprises that we've got in store that we're really excited about."

For those attempting to puzzle out Zoom's identity, this trip through the breaches has viewers wondering if Barry will come face to face with the man behind the mask, particularly if the baddie will share Gustin's visage.
