Watch the Promo for DC’s Legends of Tomorrow “Left Behind”

The promo for the next all new episode of DC’s Legends of Tomorrow has been released. The episode is called, “Left Behind” and it will air on March 31.

In the episode, “Ray (Brandon Routh), Sara (Caity Lotz) and Kendra (Ciara Renée) are shocked after they watch the Waverider fly off without them, leaving them stranded in the ‘50s. After waiting months for their teammates to come back, the three realize they must move on with their lives. Ray and Kendra bond as a couple but Sara decides to return to the League of Assassins and Ra’s al Ghul (guest star Matt Nable).”

If Sara returns to the League of Assassins wouldn’t that screw up the current timeline?
