Remove Umaro and Hidon???

So looking at the Umaro event.... There's a lot goin on I don't quite understand and idk what to change... Would I jump from where it starts to give me the esper to after the battle with umaro where I actually obtain it? There's also a whole in there of nog talking with umaro. Since I have no need of umaro and replaced his sprite what should I do with that? Sorry to be a bother guys. Don't want to mess anything up
