I am on my third playthrough and I just noticed something.
When you get to Gould's girlfriend's apartment, he thinks you are Prophet. But when you get into the suit cradle he finds out you are not because of a video of Prophet saying "remember me..." etc. But nowhere does it say who the guy in the nanosuit is, and you are not talking. In the next room, he talks about a deeply imbedded virus and how Prophet must have had something planned for you, but he still does not know who you are.
In the next segment, you escape from the area and Gould guides you along referring to you as Alcatraz. When you meet up with him at the Bank vault to do a "deep scan" the video of Prophet finding Alcatraz is shown for the first time. You can see his name tag as he is dragged off the beach and Prophet says it out loud. This is the first time Gould could have seen this.
So when does Gould find out who you are? Did I miss something?
