In a recent interview, Arrow's executive producer Marc Guggenheim revealed that fans are still going to "get plenty of Oliver" (Stephen Amell) in the rest of season 3.

Slade To Be "Out For Blood" In Upcoming Episode Of Arrow

Guggenheim spoke to TVLine about how viewers won't exactly miss Oliver as he is still going to be seen in many flashbacks. Although, he did leave some of it to keep fans excited, saying that the when and the how is all a surprise.

"You will certainly see him in flashbacks," Guggenheim said. "In fact, Episode 10 has, I think, some of the most intense flashback action we've ever had. We've got Oliver literally ziplining between buildings, as the camera follows him through a window, and there's a huge shootout.... You're still going to get plenty of Oliver. The how and the when and the why, that's all a surprise."

Mid-Season Premiere To Be One Of The "Most Emotional" And "Action Packed" Episodes 

Here's the official synopsis for the mid-season premiere, Left Behind:

"THE TEAM DEALS WITH OLIVER'S DISAPPEARANCE - In the aftermath of Oliver's (Stephen Amell) fight with Ra's al Ghul (Matt Nable), Diggle (David Ramsey) and Arsenal (Colton Haynes) continue to protect the city in the Arrow's absence. However, after three days without hearing from Oliver, they begin to fear the worst may have happened to their friend. Felicity (Emily Bett Rickards) refuses to believe that Oliver could be dead until Merlyn (John Barrowman) pays the team a surprise visit. Thea (Willa Holland) suspects there is something more behind Oliver's disappearance and asks Merlyn for a favor. Meanwhile, Ray (Brandon Routh) tests a part of his new suit and Laurel (Katie Cassidy) takes up the mantle of the Black Canary. Glen Winter directed the episode written by Marc Guggenheim & Erik Oleson (#310)."

The episode is set to release on January 21, 2015 at 8 p.m. E.T. on the CW.
