So I correctly guessed that it was Zoldeo who killed Grammi, but I am surprised that it happened like that. I thought Zoldeo killed her because he had become evil, not that he became evil due to killing her.

But at least we now have confirmation that Layla did indeed die due to not having the set together... which is a bit odd in it's own way.

The clan was supposed to bring the Dragon Slayers and Dragons into an Ethernano-rich enviroment, which isn't exactly a condition that changes quickly, so waiting for a few more weeks... or even years for that matter to gather the last key would have been just fine. Why the was it so important to immediately open the gate, even at the cost of Layla's life?

We need (or rather would have needed) some more explaining here.

But despite all that, I'm still quite pleased with the chapter. No idea why Lucy and Brandish had to become mermaids, but it was adorable, so it's fine. :3

I wonder what's wrong with Natsu. Is it backlash of using Igneel's power, similar to his sickness after eating other elements? Did something happen to the book of E.N.D. ? Or could something have happened to Zeref?
