After last week’s explosive and turbulent Season 4 premiere of “Arrow,” Oliver Queen (Stephen Amell) and the gang are returning Wednesday to find a new reason to stay in Star City fighting crime. Episode 2, titled “The Candidate,” will introduce two new characters to the DC Comics TV universe. 

According to the episode’s official TV Guide synopsis, with the help of his sister Thea (Willa Holland), Oliver will find a new reason to remain in Star City with his blushing new girlfriend Felicity (Emily Bett Rickards). Despite the season opening with the two of them deliriously happy elsewhere in the world there’s still a lot that could force the Green Arrow to keep doing his duty. Unfortunately for him, it looks like Felicity is finding reasons of her own to stay. 

“The Green Arrow and Speedy try to protect an old Queen family friend, Jessica Danforth, when she decides to run for mayor," reads the synopsis. "Meanwhile, Thea begins to exhibit effects from the Lazarus Pit; and Felicity faces a tough business decision and looks to one of her employees, Curtis Holt, for help.”

The plot synopsis teases the introduction of two new characters. The first is Jessica Danforth, whom ScreenRant notes was cast earlier this year with “Star Trek: Voyager” and “Helix” star Jeri Ryan. The second, and perhaps infinitely more interesting, is Holt, whom DC Comics fans may have figured out will bring the character Mr. Terrific to life on the show, played by Echo Kellum. Without giving too much of his superhero origins away, Holt is a technological savant and inventor working for Palmer Technologies under Felicity’s close supervision. According to Variety, the two will become friends and Holt will mark the show’s first openly gay character. 

Unfortunately, new characters might not be enough to solve all of Team Arrow’s problems. Those that saw the Season 4 premiere will know that Thea hasn’t exactly been herself since Oliver took extreme measures to bring her back from the brink of death in Season 3. Although she’s got her ex-boyfriend’s Red Arrow costume on, she’s not yet in control of herself as she almost beat a thug to death. It looks like the gang will have to tackle the after-effects of the Lazarus Pit in order to get the Thea they love back by the end of Season 4. 

“Arrow” airs Wednesdays at 8 p.m. EDT on CW.
