i finally get it,man it cost me a while,so xehanort "one who uses darkness is not fit to wield the keyblade"(obviously talking to/and about TERRA)then terra says"i dont care about being a master,this power i use it for my friends"so the whole scene means that terra is working with darkness to get more power to save his friends(VEN for the most part is the one who seems to be in danger)and xehanort ranting him saying that he cant be a keyblade master for submitting to darkness,ok so terra is like riku version 0.1
