'Legends of Tomorrow': John Constantine Returns in "Necromancing the Stone" Preview

The CW has released a new promo for "Necromancing the Stone", the upcoming fifteenth episode of Legends of Tomorrow's third season.

As the photos for the episode have shown, the episode will feature the return of John Constantine (Matt Ryan), who most recently teamed up with the Legends in the midseason premiere. Fans had been hopeful to see if and how Constantine would play a role in the remainder of the season, particularly in the season-long fight against Damien Darhk (Neal McDonough) and his rotating ensemble of villains.

"When [Darhk] was first mentioned in Arrow, there was obviously some connection between him and John," Ryan told ComicBook.com at the time. "And then with everything that happens in this episode, it does leave the door open a bit. There is obviously some other kind of relationship that they've had or backstory that goes on between him and John, which there is potential to explore."

At the moment, there's currently no telling exactly how Constantine plays a role in the episode, but it's safe to assume it has something to do with Sara Lance/White Canary (Caity Lotz) being further possessed by Mallus (John Noble). But with a recent episode of Legends introducing a new method of time travel - involving the oddly-named "time stone" - this episode's title just might take on a whole other meaning.

Elsewhere, the episode will see some sort of reunion between Wally West (Keiynan Lonsdale) and Jesse Quick (Violett Beane), after the pair awkwardly broke up earlier in the season of The Flash.

"There's a bit of [Jesse feeling like she owed Wally a chance to see her again]." Beane explained during a recent interview. "You see Wally and Jesse together in a room, and things are not what you expect them to be. And... that's about all I can say! [Laughs] It's going to be cool and, I think, pretty surprising for the audience."

You can read the synopsis for "Necromancing the Stone" below.

THE POWER WITHIN — When Mallus' power over Sara (Caity Lotz) resurfaces, she unwittingly becomes the bearer of one of the Totems. Rory (Dominic Purcell) must conquer his dark side in order to wield his own Totem power to help save the crew. Meanwhile, Agent Sharpe (guest star Jes Macallan) notices that something is wrong and recruits someone unorthodox to help.

Brandon Routh, Nick Zano, Maise Richardson-Sellers, Keiynan Lonsdale and Nick Zano also star.

April Mullen directed the episode written by Grainne Godfree & Morgan Faust.
