The second fleet of the Graylash family had been reorganised and then merged with one of the Earthborn groups. Although Quinn had managed to come in time to save the main ship of the second fleet which had the most people on board, many of the smaller ships in the fleets hadn't been so lucky.
By combining Innu's Earthborn group with the Graylash second fleet, they now were able to establish a precedent that was just as strong as before. Oscar and Owen had agreed that just because of this initial Dalki attack, they couldn't falter and back down.
Perhaps it was their plan in the first place, who knew what the Dalki were thinking, and maybe they would come back to the same spot once again.
As for Innu himself, there was no need for him to personally be around. At the moment there were no signs of another Dalki attack happening anytime soon. Instead, he had returned to one of the Bertha ships that was under his control, which was currently making its way back to earth.
