They’ve teased this all season and now the big moment has arrived. The Central City gang is heading over to Earth-2 to saves Harrison Wells’ (Tom Cavanaghdaughter from Zoom. Actually, it’s just Barry (Grant Gustin), Harry, and Cisco (Carlos Valdes) making the trek. While there, they’ll run into Earth-2 Iris (Candice Patton) and Joe (Jesse L. Martin) and stumble into trouble when they meet Killer Frost (Danielle Panabaker) and Deathstorm (Robbie Amell).

Back on Earth-1, a metahuman attacks the city and it will be up to a powerless Jay Garrick (Teddy Sears) to stop him. Judging from the trailer, it won’t all be doom and gloom. Cisco and Barry even make time for a selfie.

The Flash airs Tuesday nights at 8 p.m. on the CW Network.
