As most of you know we didnt have the cliffhanger ending that was the usual Halo style. After watching the latest Spartan Ops scene. Halsey didnt know that John was still alive. If she did, she would have surely made contact with him.
So here goes some speculation. That could play out by episode 10.
Halsey will contact John. As we get closer to the truth and the librarian, our old buddy will return to the UNSC Infinity. We will gain insight to 117’s and Halsey’s bond, he will reveal that Cortana has sacrificed herself to save him. M’dama will steal back the Librarian but only after Halsey has unlocked and uncovered the truth of the didacts hand and the meaning of the pictures from the Librarian. M’dama with the unknowing of Halsey, will figure out a way to recompose the Didact and possibly Faber.
This now will set up Halo 5, Halsey will reconstruct Cortana and with knowledge of the Librarian and give the AI a nearly eternal lifespan, to avoid another rampancy. Faber and the Didact will flee back to Requiem or another shield world/Halo installation in an attempt to fire the rings once again. Within this time a flood outbreak will occur. John will enlist the help of some old friends, Fred, Kelly, and Linda.(if still alive) They will give chase and that will set the tone for the next game.
Season two spops would be BA if we could have John as an AI bot playing along side of us, or as an unlockable character. Just under god mode capabilities. HAHA, just kidding. Seriously though, we could spend another ten episodes chasing down M’dama and fighting legions of recomposed enemies, new enemies like those giants from that deleted footage! Brutes, Heretic Elites, Warrior class Forerunners, Builder class Forerunners, the possible amount of enemies could be endless.
As I said, its just speculation, no need to flame friends. Sound to crazy?
