With Arrow's first season in the bag, cast and crew have already begun teasing what's coming up for the second season of the hit CW drama, and while speculation has run wild as to the DC Comics mainstays might pay a visit to Starling City, star Stephen Amell's interview with Access Hollywood will likely spark a new round of theories.

"The thing that makes me most excited about the show is when we were up shooting the pilot, Andrew Kreisberg and Marc Guggenheim came to me with ideas for Season 1. 'Here's where we're looking at taking Season 1.' I swear to God, all those things happened," Amell told Access Hollywood. "They sat me down after my last post-production work for Season 1 -- Andrew Kreisberg sat me down and gave me the big pitch and after I got the pitch, he said, 'OK, here's the game-changer.' The game-changer is a game-changer -- I can't say [what it is], but it's something and some people that aren't just familiar to DC Comics fans. They're more familiar than Green Arrow."

Meanwhile, recently promoted series regular Colton Haynes spoke with IGN about where his character Roy Harper might end up for the second season.

"There’s a big time lapse. We’re going to pick up a little later, not right off the bat. So we’re going to have to deal with The Glades and what’s happening to them," Haynes said. "I think there’s going to be a point where Roy’s going to have to figure out what’s going to be next. Is he hopefully becoming Oliver’s sidekick? What is that going to mean for Thea, because obviously she has no idea that her older brother is the vigilante? There’s a lot of ways it can go, and also there’s a lot to be said about what Willa’s character Thea can become."

Arrow returns for a second season this fall on The CW.
