E2 almost always seems to be missing important information that Mr. Robot seems to control

In DID, the dominant personality doesn’t always have to share information freely with alters and so, it would be easy for an alter to constantly seem out of the loop and even unreliable or intentionally misleading (they theoretically could possess only a few chapters of the book of any particular period of time).

Remember, even at the very beginning of the entire story (told out of sequence) Elliot suggests that he doesn't really know when it all started both when he was talking to his therapist Krista, and later he mentions that he first noticed something underneath his consciousness when he was pushed out the window by Edward and again at the infamous Halloween meeting with Darlene (maybe the most exposition-filled scene in the entire series).

Most famously on Mr. Robot, Elliot (E2) asks us to find the Red BBQ menu that was “lost in his apartment” and then uses Lucid Dreaming to “Hack” Mr. Robot’s memory of his meeting with Tyrell Wellick. Yes, I am arguing that Elliot was reliving Mr. Robot’s last meeting with Tyrell as Mr. Robot slept (remember, to the camera, if we are not experiencing E2’s POV, Mr. Robot would appear to everyone as Elliot - only in Elliot’s head are there 2 personalities).

Let me clarify, to E2, Mr. Robot appears as his dead Father but when Mr. Robot is in charge of Elliot Prime, he looks to the world to be exactly the same person as the Elliot we all (think) we know and love.

Why is Mr. Robot in control of all of every bit of information having to do with Tyrell Wellick after 5/9? If you have read Red Wheelbarrow, you know that virtually the entire book is E2 begging to know what happened to Tyrell (meanwhile we know that Mr. Robot is secretly communicating with Tyrell throughout Red Wheelbarrow about Stage 2).

Why was Mr. Robot in charge of Elliot for a long enough time that he could work out the details of the 5/9 hack with Tyrell (including having Tyrell disappear into a Dark Army warehouse, set up Stage 2, negotiate with Tyrell Wellick throughout their entire stay in jail, cause E2 no end of trouble in jail, meet with Tyrell Wellick and so many other things. And, if he is the dominant personality, why does E2 never seem to remember any of it?

If Elliot (E2) is not controlling the flow of information, if he needs to negotiate from a position of weakness, this would suggest he is the alter and not the dominant personality. In the past, I have assumed that Elliot’s weakness was a protective device (he was protecting himself from knowing, for instance, some of the terrible things that he has done) but It occurs to me now that it could just be that he isn't in charge and can't access what Mr. Robot doesn't want him to see.

Mr. Robot could have decided that most of the time, he doesn’t believe that Elliot just does not need to know.
