While the CW's Arrow has ensured that Oliver Queen hasn't been too lonely so far, whether it's been the constant presence of Dinah Laurel Lance or Tommy Merlyn, there's been one Green Arrow character who's been noticeable by his absence so far on the series. That'll change next year, when Teen Wolf's Colton Haynes joins the show as none other than Roy Harper.TV Guide has the news that Haynes will be added to the series as a love interest for Oliver's little sister Thea late in the show's first season, with his character being "destined to become significant part of her life and an important player in the larger world of Arrow," according to information released by the CW. The kind of important player who'll turn into a sidekick in the lead character's war on crime, perhaps?

The network also describes the character as "a handsome, street-savvy, teenager from 'the Glades,' the harsh, poverty-stricken portion of Starling City," but it's the CW: How poverty-stricken and harsh can we really be talking about? "We were big fans of Colton from Teen Wolf and we are thrilled he's joining Arrow," executive producer Greg Berlanti said of Haynes' addition to the cast; we can only hope that no-one has told him about the eventual fate of Roy Harper in the original comic books.
