Lately, whenever Happy says that he'll find a way to save Natsu, what does he do? absolutely nothing. He doesn't contribute anything. How is he gonna save him? he's weak and incapable of doing anything. He just makes an exposition and then it's forgotten. The only contribution he did it preventing Zeref's eradication, thus allowing him to cause more harm.

I also don't understand why Natsu is acting like his encounter with Zeref never happened and why it hasn't been brought up since?
