So I'm assuming that she's Black Canary, since she mentioned some "self-defense" courses and was able to take that thug down easily. Well, and because of her name, obviously. But are they going to claim she's wearing a wig too? Because that blonde hair was way too light to be her own. That's got to be a bit of a pain in the ass, pinning your hair up under a wig before you can jump into your costume and kick ass. But...comic books!
I was honestly hoping they'd get someone else to become Black Canary, but I guess that would have just made creating stories for Laurel that much harder. Unless somehow they are having Summer do it, but I doubt it. Seems they want to get her away from the ass-kicking characters she usually plays, which is good.
