Hmm... so does that make Wendy X Chelia canon? And yeah, what's up with Gildarts and Cana... that's a rather... disturbing context there Hiro.

So Natsu actually did seriously try to kill Zeref... hell he totally vaporised his entire body into dust! I didn't see that coming and I kind of like it.

So Celestial Spirit Mages are the best suited to open the gate... which probably means that when Zeref goes into the past, Lucy and Anna will follow and probably drag others with them.

I just don't see any way they can defeat a Zeref who can literally reconstruct himself from dust, so going into the past seems the only solution at this point.
