Newbie here.
So Tina is a cop. Really hope she doesn't turn out to be a LI for Oliver because are they really going to have Felicity date a cop and then Oliver date one? Really?
And if she does turn out to be a LI for Wild Dog (didn't I read that somewhere on here as spec?), hopefully O and F (assuming she and the BF are done by then) advise him that dating a cop as a vigilante is a HORRIBLE idea.
