Colton Haynes Joins Cast of 'Arrow'

Former Teen Wolf star Colton Haynes has joined the cast of Arrow as Roy Harper, a character who has a complicated history in DC comics.

 Roy Harper was variously the civilian alter ego of Green Arrow's sidekick Speedy, Teen Titan's Arsenal, and Justice League's Red Arrow - ugh!

Nobody is yet talking much about Haynes' character on Arrow, but what really matters is if he gets to train with a shirtless Stephen Amell.
