Guys your siding with Miskos3 who has shown no evidence for his statement about END?

Zeref said to Natsu that he will have to decide to let END live or not.

Igneel said that he believed that Natsu could beat END.

Igneel and Zeref both said that END was close to being revived.

Zeref specifically calls the book of END Natsu and talks to it and telling it about Igneel and planed to talk about Mavis its as if Zeref was talking to a person who he hadn't seen in a long time.

Why say all of this that which clearly points toward a split personality and think that their is nothing when everything shown in the manga clearly points in the opposite instead.

Guys as for the silver thing that really isn't a inconsistency as silver himself said to get grey angry inorder to kill him so it actually makes sence.
