Exactly what I was thinking - that to have been fake, he maintained character of MZ quite well. Further, I would doubt that he would have known exactly the whereabouts of MZ during that period. So to be able to know and make claims as to when he was where, refer to the other people and make up stories about wanting to drop the site, take down the server and the fact that his parents could cover his college, all while in character is quite an accomplishment.

BTW, I wrote this in Zuckerberg's voice as portrayed by paul ceglia via DLA Piper dispositions.
