Stanley knew she had the Canary Cry. At the very least, Dinah had been outed as the Black Canary the week before and had publicly showed her powers. Stanley even had the newspaper of her screaming.
I've almost always liked Dinah; I just hated WHY she was brought onto the show. And most of last season, which I am choosing to ignore.
Echo Kellum gave an interview where he said he was leaving to spend more time with his son, and to pursue other avenues other than acting. Though he did say that he is welcome to coming back in a guest spot every now and then.
I can see it now, for Crisis next year they bring everybody back- and kill them all. Except Thea, whom they won't kill.
I haven't minded this Future story as much as most people, but I think this week is my breaking point. You mean to tell me that William NEVER met Mia? Even when she was a baby? You mean that he still calls Felicity his mother, but apparently she never had contact with him once he left with his grandparents? You mean his dad never mentioned his new daughter in a phone conversation, or sent him a picture or anything?
I could buy it if she was an adopted daughter that came into their lives years later, but not as a biological child, which looks to be what they are setting up here.
