I can see it now. Dead Orbit is gonna bail on the last city to find a new home. The darkness is gonna close around the survivors. The brave guardians of New Monarchy and FWC will slowly be pushed back taking massive losses. Just when the city looks lost and humanity ended, Dead Orbit is gonna pull a Han Solo and come back to flank the enemy. The darkness will die in an epic explosion and Bill the Cabal will be like "Oh Snap!" as he floats away in a damaged tie fighter.
