More familiar faces are heading to "Legends of Tomorrow" season 3.

Another speedster is making an appearance on the superhero show. Entertainment Weekly reports Violett Beane, who plays Jesse Quick in "The Flash," will reprise her role on "Legends of Tomorrow's" third season. The actress has been tapped to appear as a guest star on episode 15 titled "Necromancing the Stone."

So far, further details about her arrival are still being kept under wraps. Her casting comes on the heels of "The Flash" actor Keiynan Lonsdale joining the show to reprise his Wally West role. He was briefly seen at the end of Monday's episode as Rip Hunter (Arthur Darvill) recruited him.

A day before Bean's casting was announced, ComicBook.com confirmed with Warner Bros. Television that Jonah Hex (Johnathon Schaech) will also be returning this season. He is slated to appear on the show's season 3 finale airing this spring.

Lonsdale's casting initially caused speculations about Jonah's potential return when he posted a photo of the cast filming the season 3 finale via Instagram. Star Caity Lotz added more fuel to the fire when she shared a photo of herself sporting a Wild West costume, hinting at the new setting.

Titled "The Curse of the Earth Totem," next week's episode will see Sara (Lotz) take some time away from the team and reflect. The Legends then take on a new mission as they search for the long-lost Earth Totem without letting Sara know about their plans.

They later find themselves in 1717 while hunting for Blackbeard's long-lost treasure. While things take an unexpected turn for the group, Ray (Brandon Routh) starts to feel guilty about a mistake he did in the past. He tries to make amends but his efforts will, later on, lead him to more trouble.

"Legends of Tomorrow" season 3 airs every Monday night at 8 p.m. EST on The CW.
