But yeah that paper points out a lot of crazy shit. I didn't read all of it because there's a lot of words and stuff, but really not a lot of the ending makes sense. I didn't notice a few of the things it mentioned but when the illusive man showed up I was wondering why the hell he could control me when there were parts specifically saying he couldn't. The only way he could control you is if you were indoctrinated and he was taking advantage of the research on sanctuary to control you.
