OMG, so it is Natsu's fault that Lucy's mother died, that is so sad, than again so did Gajeel, so did Wendy, so did Sting and Rogue, in a way it is all their fault. Okay I am sure that is not the way Lucy sees it thankfully.
At first I thought having her key broken mellowed out Aquarius, she so nice to Lucy, this is not the Aquarius, than we saw her talk to Brandish, that is the old Aquarius we know.
It might to convenient that Aquarius resolved this misunderstanding. So if Brandish the same age as Lucy, that mean physically she is 7 years older? So I assume Jude took on Layla's family name when they married, if the bride family is that powerful and important than that happens. And we got to see Anna, that was fast, Hiro moves at a fast pace.
So technically for Natsu and the other dragon slayers sake, Layla died for them. I wonder how Natsu would feel if ever found that out, I bet Zeref would tell him that just to give him more despair.
So that Zolido killed Grami, and because he was sad that Layla died, I thought he didn't care about her and he was just a greedy person, that is what it seemed in the Tenrou Island arc.
Natsu is in trouble, what I said about Natsu and the other dragon slayers being partly responsible for Layla's death that could come into play next chapter for real, because Layla died Zolido went crazy and killed Grami, so if Hiro wants to keep Brandish an antagonist just a bit longer, perhaps with Natsu dying and in danger, maybe in her logic she will blame Natsu and the dragon slayers for all this, and try to kill Natsu, and try to get Lucy to team up to kill Natsu. I could say Brandish being all "if it wasn't for all those dragon slayers none of this would happen, our mothers would still be alive." If she wants revenge on someone, Zolido, so blame the dragon slayers, we will see.
Anyway great informative chapter.
