Think about it. In the book Halo: FS, their are 4 other spartans who survived Reach and go with the MC. Linda, Kelly(who gets kidnapped by the doc), Fred, and will. Now I do not kno if this is true, but don't all the books have to be verified by Microsoft and Bungie so the books can fall in with the games? On top of that, in the FoR, they mention that 3 other spartans cannot be recalled to reach for the bigt mission because they were to far out of system.
I would like to see Bungie put this in Halo 2 as well as explain what happened to the other spartans.
