Metkayina vs Mangkwan!?

I'm going to put this as a spoiler/theory...but I think it fits more as a theory...anyway

I think many have already come to the conclusion that Varang and the Ash are in the grave of their Metkayina ancestors...But why?

My theory is that while Quaricth is learning Varang, he is giving her suggestions and encouraging her to hunt Jake too for some reason,Since Quaricth probably no longer has as much support from General Ardmore as before, he would now have his own army that knows the Na'vis' weak points...And that's an advantage he never had...

However, I assume that before they reach the Metkayina clan, Jake and his family would have already left for the forest... and when Varang attacks the Metkayinavillage with Quaricth, It would be a really interesting fight between clans that symbolize fire and water, but I think the Ashes should have an advantage because they are armed and in ikrans, however they won't find the Sullys But Quaricth will know where they might be and will go after them in the omatikaya forest...where we have already seen a Varang art among the floating mountains -What do you think?
