Colton Haynes teases return as Arsenal in "Arrow" season 6.

The former "Arrow" regular took to Instagram to once again tease his comeback for the crime drama. He posted a photo of him with co-star and former on-screen love Thea Queen (Willa Holland) and captioned it with "#TheaRoy ...I ship it too."

This latest teaser answers the question on whether Haynes, who plays Roy Harper a.k.a. Arsenal, will be re-igniting his romance with the younger Queen for his return.

A couple of days before, he also posted a shot of him with his former team -- Stephen Amell (Oliver Queen), David Ramsey (John Diggle), Emily Bett Rickards (Felicity Smoak), and Holland.

Looks like the 29-year-old is so excited to make his "Arrow" return as he captioned the photo, "Friday's night shoot with my #Arrow fam... guess who's back... back again."

Haynes' character, Roy, has been virtually absent from the series since he pretended to be the Green Arrow and faked his own death to protect the identity of his mentor Oliver.

His then-girlfriend Thea wanted to go away with him, but Roy knew better than take her to a life on the run. Thea then goes back to Star City, and in honor of Roy, donned Arsenal's costume in the name of Speedy.

Last month, executive producer Wendy Mericle and former EP Marc Guggenheim revealed to in a statement the reason for his return. "Roy is called back to Star City to help resolve an urgent matter with high stakes for the team," they said. The duo added that it would be a short visit, but it would have a surprising twist when Roy meets Thea for the first time in years.

Haynes first teased his return to "Arrow" back in September, when a fan told him via Twitter that he is very missed from the show. To this, Haynes answered, "Roy's coming back very soon."

"Arrow" season 6 airs Thursdays, 9 p.m. EDT, on The CW.
