In an article dated August 12, Movie Pilot stated that Malcolm Merlyn will be back and wreak havoc not as himself but in the avatar of the Dark Archer. It has also been suggested that Merlyn's daughter, Thea, will go to the dark side under his guidance.

In an interview with Zap2it earlier this year, Barrowman was cautious about giving away too many spoilers but fans knew he was definitely returning as a series regular.

"I know some of what's going to happen," he said. "And for Arrow fans, it's going to be an amazing Season 3."

The actor went on to speak about his charcter's immortal powers, like when he was brought back to life after season 1.

"What you have to understand is that Malcolm Merlyn, he might not have died," Barrowman said. "He just knows how to do things -- in the same realm as Sing Your Face Off -- to do an impression of being dead. It's not always what it looks like and things are explained later."

The official press release for season 3 of the show was released last month:

"After a violent shipwreck, billionaire playboy Oliver was missing and presumed dead for five years before being discovered alive on a remote island in the Pacific. He returned home to Starling City, bent on righting the wrongs of his family and fighting injustice.

To do this, he creates the persona of the Arrow and allies himself with former military man John Diggle (David Ramsey), computer-science expert Felicity Smoak (Emily Bett Rickards), street brawler Roy Harper (Colton Haynes) and international assassin Sara Lance (Caity Lotz), while keeping his secret from those closest to him including his sister Thea (Willa Holland), who has allied herself with his most deadly enemy. Rivalries and allegiances will shift as Oliver faces his most difficult challenge yet."

The finale of season 2 of Arrow aired on May 14 on the CW. Season 3 premieres on October 8 on The CW.
