yeah this definitely irked me a bit, I was playing coop with a friend and I've read the books so I understood, but he was like "who the **** is the didact!?"

From reading the first forerunner book I have my own, similar, theory. Not that M.C was always a forerunner, but rather the librarian has performed a sort of brevet mutation to M.C. When Bornstellar performs a brevet mutation with the didact in the book he can hear the didacts thoughts afterwards. We see M.C hearing the didacts thoughts without Cortana hearing them. Also i agree the legendary ending face looks interesting. I feel the nose looks flatter than a regular human, similar to the didact and the librarian. Also His eyes have very dark patches under them which can be seen on the librarian. (Of course this just could be due to the fact that he has had the helmet on for over 4 years) Anyways, in the books, (from what i know, or believe i know) the original didact is killed. and bornstellar eventually becomes the replacement didact, because he has the genes of the orignal, including his memories. It would be interesting to see where 343i takes this, possibly having master cheif slowly become the didact. Everything I've said could be wrong, and I welcome anyone who has facts disproving what i wrote.
