True but that still seems to be a hugh oversight regardless, Laurel's mother aside, for both Black Canary's to have the same first name Dinah when both characters are traditionally related. They have altered relatives relations in these things before, Iris and Wally West being prime examples as they are siblings as opposed to aunt and nephew. Also as I said, Quentin recognised her. I'm convinced there is a relation.
