After seeing that Blue team is back in Halo 5 it raised questions for me. I read all the novels that I know of. I thought Kelly (or Linda, I forgot which was the sniper) went MIA(as "Spartans never die") in the book The First Strike when the covenant space station exploded. And I thought Fred was trapped in some kind of slip-space containment field with Dr. Halsey and a few from the Spartan III program as per the end of Ghosts of Onyx. Though as in Halo 4, Halsey clearly got out, and the rest could have as well, I just don't know how or when they got out.
