Last episode, fans saw how John Constantine brought back Sara Lance's soul to her body. In "Arrow" season 4 episode 6, fans will now see the revitalized Sara as they try and rescue Ray Palmer.

For fans craving for some "Arrow" season 4 episode 6 spoilers, here's the synopsis of the upcoming episode courtesy of Comic Book Movie.

"RAY PALMER RETURNS FROM THE DEAD - Felicity (Emily Bett Rickards) is frantic when she learns that Ray (guest star Brandon Routh) is alive and being held by Damien Darhk (guest star Neal McDonough). Felicity's guilt over not finding Ray sooner causes tension between her and Oliver (Stephen Amell)."

"Meanwhile, Sara (guest star Caity Lotz) joins Laurel (Katie Cassidy), Thea (Willa Holland) and the team on a rescue mission for Ray. However, the effects of the Lazarus Pit take over and threaten to jeopardize the entire operation. Donna Smoak (guest star Charlotte Ross) returns to Star City.
