‘The Flash’ Sneak Peek: Zoom Tempts Caitlin Towards the Dark Side

Here’s the official episode description for “Rupture”: Zoom arrives back on Earth-1 intent on taking over Central City.

The CW recently renewed “The Flash” and a slew of other shows for its 2016-17 season.

In the May 3 episode, “Rupture,” Zoom and Caitlin have returned from Earth-2, with Zoom intent on conquering as many alternate Earths as possible; and since Barry (Grant Gustin) is still powerless, stopping the multiverse-hopping villain will take more than just speed.
