A long-suspected character is coming to the third season of Arrow. Or, we should say another, now that we know Ra's al Ghul is coming.
The character Ted Grant, aka Wildcat, is going to be coming in, and he's going to be spending some time around Laurel.
Trivia: Wildcat is the person who trained the Black Canary. Hmm.
