If Age's painting is right (and I assume they are), Mehitaka will probably be ordered to destroy another planet, and it will probably be Earth. The Silver might be driven away from this battle if Age starts to finish off one of the Nodos, and they'll probably have Yuti force him to destroy a planet to demoralize the humans.

With any luck, the younger of Deianeira's idiot brothers will be killed in the blast, and her older one will live to be thoroughly disgraced.

They've now said it outright, but I wonder why part of the deal is to have Yuti never fight.
