GUYS GUYS GUYS I FOUND HIM!
I was watching the Avengers for what may or may not have been my 35th time, when all of the sudden someone caught my attention in the part where Fury is talking to the council.
Our little friend, Gideon Malick. I have no idea how I did not see him all the other times, but I am sure it is him. He was the guy encouraging Fury to proceed with Phase 2 (creating weapons with the tesseract). Now, how that ties in with bringing Hive back, I do not know.
I know I am not the first to see it, but still.
