Colton Haynes has been promoted to series regular on the hit CW Network series Arrow, after just one guest-starring appearance.

The actor debuted as Roy Harper, the boyfriend of Willa Holland's Thea, on the February 20th episode "Dodger". It isn't immediately known when Roy will appear next, although an executive producer recently teased that the character will be popping up more throughout the rest of this first season.

"We're going to see more of Roy in Season 1, and some glimmers of where his potential could be."

The series returns after a short break with the new episode "The Huntress Returns" on Wednesday, March 20 at 8 PM ET on The CW. Given the title, it's fairly safe to say that Jessica De Gouw's Huntress will play a major part in the episode.

Colton Haynes previously starred on MTV's Teen Wolf and The Gates.
