Amell spoke to TVLine and suggested that the Waller, who is enacted by Cynthia Addai-Robinson, flashbacks will shape Oliver's journey in season 3 of the CW series.

"Oliver lost a lot of his humanity in those five years [away from Starling City], so as we see that continue to happen it in the flashbacks," he said. "We will see how much of his humanity he wants to get back in the present."

The official press release for season 3 of the show was also released earlier this month:

"After a violent shipwreck, billionaire playboy Oliver Queen (Stephen Amell) 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 release date for season 3 has not been revealed yet.

The finale of season 2 of Arrow aired on May 14 on the CW.
