What Oliver Queen did with the finest in trick arrows and booby traps, Dinah Lance is going to do with her bare hands.
Why? Because it's been a long time in coming.
For the stupidity of thinking a bag over her head could stop her. (Identity Crisis)
For the indignity of holding her hostage with a sword in her mouth. (Green Arrow Vol. 2 #75)
For crashing her wedding just because he could. (Green Arrow/Black Canary Wedding Special)
And because the only thing that stopped her from doing it once before was her friends getting in the way and becoming hostages before Dinah could really go to work. (Birds of Prey #90)
At some point, Dinah is going to settle her accounts with Slade Wilson. With interest.
