i just thought about the natsu=end. i just dont think thats gonna happen, because zeref said they were two different beings. but how bout this: end was created to kill zeref, but igneel thought it was to dangerous for some reason. he convinced zeref somehow that natsu (or any human, maybe and he just happened to pick natsu) could be made strong enough, if he had the time to train. so zeref was like "kay, if he can defeat my end, he can try", went sleeping (he was sleeping on tenrou island) and awoke. when he saw natsu, he recognised the boy (he said something about natsu having grown) and thought he was ready to kill him. he even let natsu punch him. however natsu was still to weak. back then he wondered and not stated, meaning he expected natsu to be stronger then him. With natsu being end, he would have known his power from the begin with, meaning he underrestimated himself. he would have talked about himself and not about natsu. (chapter 209)
