This episode put eveyone's lives in danger, and even claimed the life of a main character on Earth-2. In next week's concluding episode, "Escape from Earth-2," Cisco and Wells must recruit help in order to rescue Earth-1 Barry from the hands of Zoom.

In the video below, "The Flash" executive produces Todd and Aaron Helbing explain how Earth-2 Barry can help the team, and what lies a head for the characters from Earth-1 and Earth-2.

"Escape from 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 rushes to perfect Velocity-9 so that Jay can stop the Geomancer.

"The Flash" stars Grant Gustin, Candice Patton, Danielle Panabaker, Carlos Valdes, Tom Cavanagh, Jesse L. Martin, and airs Tuesdays at 8 p.m. on The CW.
