The return of the Flood.

Infinity finally tracks Spirit of Fire and gets infected. Everyone on the crew gets infected except for Lasky and Thorne(they’re the best characters lately added to the series). A gravemind is created, travels to earth contaminates earth. Bornstellar and some surviving forerunners return from outside the galaxy to aid Chief, Arbiter and Ur-Didact against the flood. I feel Cortana(Although confirmed dead) will have a very big role in somehow changing Ur-Didact’s view of humanity.

I have no idea where to place Locke at the moment, he remains a big mystery.

I want to finally see some huge space battles, field battles, something on a really big galactic scale. Something epic again.

This. Oh god. This. The chills down my spine
