<Snipped quote by Stabby>
Mind Shinji: I am him. Well, a part of him he thought of before he went to sleep. A proxy Shinji, if you will. I am here to ride you over until it is safe to return to reality. There is a lot of commotion going on outside, related to the Balkan System, and Shi- well, I got dragged into it by Mierno. Once all is safe, and we return to the base, you should be okay to safely exit.
Knowing how this works myself, you're kinda like the inverse of Record. Instead of sending himself in here and leaving a self programmed biological AI in charge of his body, he's created you and sent you in while he deals with the world outside, right?
