DC's Legends of Tomorrow will soon get visited by both Jonah Hex and Talia al Ghul when it returns to The CW on Thursday.

A new trailer released during WonderCon shows the two characters as they will appear on the show, which plays into previous teasers about Jonah Hex, as well as confirms the fact that Talia exists in the DC television universe.

DC originally teased Jonah Hex through a wanted poster seen in the background in one episode of the series. Of course, that begs the question if the other Easter eggs on the show hint at more characters we can expect to see.

Fans have also long wondered about the existence of Talia in the DC television universe, particularly since Arrow focused on Ra's al Ghul's other daughter, Nyssa. However, Talia appears in the clip as a girl, training with her father. How she will play a part in the story on Legends of Tomorrow, though, is still anyone's guess.

The trailer also teases Jewel Staite's character, as well as Arrow's Felicity Smoak and Quentin Lance.

Legends of Tomorrow recently got picked up for a second season, but the good news is that fans following this season will still get a definitive ending for this particular cast of superheroes. The idea is that the show will act as an anthology, bringing in new characters from DC Comics every season for a new story.

"At the end of this season, you will get a definitive end of this chapter," Marc Guggenheim, executive producer, said at a panel at WonderCon, as reported by IGN. "You'll get an answer about whether or not the team succeeds to stop Vandal Savage. You'll get a resolution of the love triangle. You'll get to know more about what the Time Masters are up to. I don't think there are too many unanswered questions at the end of this season."

What's the love triangle Guggenheim refers to? It seems that Kendra's blossoming romance with Ray will run into a major problem: her dead lover, Carter.

"Poor Ray," Ciara Renee, the actress behind Kendra, aka Hawkgirl, said. "Kendra's going to start remembering her past lives with Carter. In many ways, Ray is going to be competing with a dead man. It's a complicated situation."

DC's Legends of Tomorrow returns at 8 p.m. EDT on March 31 to The CW.
