Interesting. Particularly the part about Sayla wanting to kill Mira. And of course also the part about Igneel's and E.N.D.s powers, but I don't think either of the scantilations said anything about power and only mentioned how Igneel was unable to kill E.N.D., but that can mean so many things (lack of power, lack of resolve, END being so fast that it could run away from Igneel and more).

How exactly Zeref calls Tartarus is ultimately of little consequence, but which of the two sisters Sayla wants to kill is quite relevant. It might also show that, at least as long as Lisanna doesn't attack her, Sayla still seems willing to keep her promise to Elfman, even though he failed her. If that turns out to be the case, we'll have learned a little more about Sayla's character.
