Arrow Season 2 will be nothing like its first season, says lead star Stephen Amell. Some fans took it as a hint that the vigilante Hood Guy's team of three will be expanding. Ollie's BFF Tommy, however, is definitely gone. So who's the next member - Black Canary, Speedy or both? It is understood the crew is considering the implication of adding new costumes in the show. Whatever happens, Katie is keeping her bod in great shape through diet and exercise.

Black Canary is Green Arrow's on again, off again love interest in the DC comics. In The CW's Arrow Season 1, Dinah "Laurel" Lance and Oliver Queen are not exactly official, at least not yet. But then TV fans are clamouring for more Olicity (Oliver and Felicity Smoak) scenes. The three could be in for a complicated bad romance.

Speedy aka Roy Harper, is Green Arrow's teenage sidekick. Colton Haynes is playing the role. By the end of Arrow Season 1, the character is on a mad quest to find the vigilante Hood Guy - even after Oliver Queen tried to scare him out of his mission.

In The CW Upfronts in May, Cassidy talked about her character getting tougher through the dramas and circumstances of the last season. She sees this as part of her journey towards becoming Black Canary. In a separate interview, Haynes said the writers could be making him wait before turning into Speedy. The transition might take time, and there is no telling when the two could be wearing their respective costumes. They are certainly preparing for it, though.

In an interview with Kelli Zink of Celeb TV, Katie Cassidy reveals her gameplan to stay in great shape. Black Canary wears a smokin' hot costume, which is a popular favorite in cosplays. Only fishnet stockings are keeping her gorgeous legs from being fully exposed. If Stephen Amell works out for his abs-bared scenes, what is Cassidy's fitness routine?

"I try and mix it up, and do as much as I possibly can," the actress says. Cassidy, who may or may not be donning Black Canary's costume on Arrow Season 2, says she does both yoga and cardio. "I also have been fight training," the actress adds. Black Canary is feisty in hand combat, so it is not surprising Cassidy has fight training in her schedule.

When it comes to food, Cassidy says pizza is her favourite. She tries to eat healthy when they're filming, but otherwise, she allows herself to enjoy some gastronomical delights. "It's all about moderation, too," she says.

The CW Arrow fans may or may not see Katie Cassidy in Black Canary costume when it returns for a second season. If you're a fan, though, it is best to keep your fingers crossed for at least three Arrow seasons. You don't want to see a good show get cancelled before seeing the best of what it could offer.

Thanks to all you followers!!! I appreciate you! And all the love! Love right back at ya!
