Laurel Lance will continue to face the consequences of resurrecting her sister Sara through the Lazarus Pit on Wednesday night's all-new episode of "Arrow."

Last week, Sara Lance was brought back to life after Laurel dumped her dead body into the Lazarus Pitt. However, after being restored, Sara immediately went on the attack and had to be restrained with chains, notes Entertainment Weekly. Following Sara's revival, Nyssa al Ghul destroyed the pit because she does not want anyone else to experience the type of suffering that Sara endured after being dipped in the pit.

In the next episode, "Beyond Redemption," Laurel will face serious consequences after bringing Sara to life. According to Carter Matt, the synopsis reads as follows:

"Laurel (Katie Cassidy) must deal with the repercussions of taking Sara (guest star Caity Lotz) to Nanda Parbat. Meanwhile, Oliver (Stephen Amell) asks Captain Lance (Paul Blackthorne) for a favor and while he's not surprised at the response, he is surprised at what he finds out next."

Later on in the season, viewers will finally learn what about happened to Ray Palmer in Episode 6, reports Cinema Blend. Although Brandon Routh's character appeared to die in a blast during the Season 3 finale, it turns out that he was really kidnapped by Damien Darhk.

A synopsis for the upcoming episode, "The Lost Souls," states the following:

"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."

"Arrow" Season 4, Episode 4 will air on Wednesday, Oct. 28.
