Earth 2 has been a big part of this season for The Flash and it looks like Barry and his friends will be crossing over in upcoming episodes to deal with evil versions of both Robbie Amell as Deathstorm and Danielle Panabaker (from Caitlin Snow to Killer Frost).

I’m not sure how much of this trailer is just for this week’s episode, but it seems like way too much for just one hour. Either way, it looks like the back half of this season is going to be pretty nuts.

Here’s the synopsis for this week’s episode:
Now that they’ve grown closer, Barry considers telling Patty (guest star Shantel VanSanten) that he is The Flash. Meanwhile, Joe and Iris try to get to know Wally (Keiynan Lonsdale), and the team hunts down a meta-human who can slow time itself.
