Holy shit, I just figured it out.

MATTIS CAME UP WITH THE IDEA FOR Q.

Mattis on reading:

" Thanks to my reading, I have never been caught flat-footed by any situation, never at a loss for how any problem has been addressed (successfully or unsuccessfully) before. It doesn’t give me all the answers, but it lights what is often a dark path ahead."

Q: "Read, re-read" "dark to light"

We all know Mattis is one of the most well read men, Q's tripcodes all point to different books, all books which I bet Mattis has read.
