User blog comment:BlackWizardZeref/Fairy Tail: Chapter 436 Memoirs Review with a brief mentioning of Chapter 435 Victory Shout!/@comment-24546844-20150519194644

Interesting theory. I like the eclipse thing but the problem comes when we think back of what happened to FRogue when Eclipse got destroyed. If the theory is right then Natsu should also be sent back to his original timeline. Well, right now the timeline logic of the series is a bit messed up for we to fully understand the events but I guess Mashima will just find an excuse for it.

Anyway, people's been talking about Tartarus and how E.N.D. is supposed to be their master so I'll rise a question I've beeen thinking about for a while. If Natsu is E.N.D. and is Tartarus guild master, yet they never actually met them, and if Igneel trained Natsu some time before he was born and thus teaching him his fire magic, how could Silver know that E.N.D. is a fire demon? Could we assume Zeref revealed it to Tartarus some time before? Or did Silver somehow knew that E.N.D. was Natsu?
