Actress Caity Lotz as Sara LanceThe CW

This upcoming episode of Arrow season 4 will focus on the resurrection of Sara Lance. After Thea, Sara will be the next member of Team Arrow, who will be brought back to life using the mystical Lazarus Pit. However, it doesn't look like entering Nanda Parbat and taking a dip in the Pit, will be as simple as it sounds.

According to the official synopsis for Arrow season 4, episode 3 titled, Restoration, the growing tension between Oliver and Diggle will put both their lives at risk when they go after Damien Darhk and a Hive deployed meta-human.

Meanwhile, Laurel will talk Thea into returning to Nanda Parbat to ask her father, Malcolm Merlyn aka Ra's al Ghul, to put Sara (guest star Caity Lotz) into the Lazarus Pit. However, Laurel is surprised when Nyssa (guest star Katrina Law) refuses to do so.

Nyssa has been around The Lazarus Pit for much longer and clearly knows more about the dangerous after-effects of using it. And if she feels that it is wrong to bring Sara back from the dead using the Pit's powers, it has to be for good reason.

Well, one thing we know for sure is that Sara will experience adverse effects from using the Pit after she has been resurrected. In fact, it will take another DC superhero to help her deal with those after-effects, as teased in the episode 5 synopsis which states that, "When things take a turn for the worse with Sara, Oliver calls in a favour from an old friend who deals in the mystical, John Constantine.

In a recent interview with TV Guide, Arrow and The Flash spinoff series, Legends of Tomorrow showrunner Phil Klemmer revealed that Sara would return as a ruthless, cold-blooded assassin who's lost all humanity.
