More new faces are coming to "Arrow" as the Queen siblings both get respective new love interests in the show's upcoming fourth season. Just recently, "Enlisted" alum Parker Young and Elysia Rotaru from "iZombie" joined the cast. 

The former will play the role of Alex Davis, a smart and driven young man. HIs work with Oliver brings him to Thea's life. With Roy (Colton Haynes) out of the picture and the expiration of the actor's deal with the show, Thea is bound to move on. 

Rotaru, on the other hand, will play the role of a love interest for Oliver from a flashback. Olicity fans need not worry as she is more of an old flame rather than someone who is going to break off Felicity and Ollie's relationship, basically because she is a thing of the past. But Ollie's flashbacks almost always intermingle with the present and this is what executive producer Marc Guggenheim hinted at during a chat with EW. 

"Oliver is gonna have a love interest in the past that will serve as a parallel or potentially a contrast to his love affair with Felicity in the present," he said. 

Oliver will also be seen tackling some bad guys from a crime organization that goes by the name Shadowspire. Jimmy Akingbola will play a loose adaptation of its group's leader, Baron Reiter (Baron Blitzkreig in the comics), and Ryan Robbins as the group's ruthless member Conklin. 

The latest addition to cast is Rutina Wesley from "True Blood." The actress currently stars in "Hannibal" as Reba but will appear in the DC Comics adaptation for a multi-episode arc in a still undisclosed role. She joins "Teen Wolf" actor JR Bourne, who has been cast as villain Double Down.  

"Arrow" season 4 premieres Oct. 7.
