They don't need to happen back to back, just let it happen one event happen to something that goes on for few months. Then goes back to normal for a while, they just need long space between each other.
An Excellent choice for the role Amanda Waller, I'm happy she got the role. Her role on "" shows me that she has what it takes to get that role. Viola Davis has what it takes to nail the role. Congratulation to her!
My main concern is the role for Amanda Waller. but I can't see it being other than CCH Pounder; she has been the voice and I believe that she can take on the role of being in charge of the Suicide Squad. When she speaks you can hear the Commanding Authority coming from her whenever she speaks, it matches pretty well.
