Well, there's that too...but I'm trying to think of the best case scenario for Irene.Didn't August himself say there is zero chance without FH? I'm generous if I say Zeref, August and Eileen are even 5% Acnologia lol
FH Zeref was planning on firing unlimited Etherions to take down Acnologia. And a single Etherion > August and Eileen
Actually Zeref's plan involves simply going back in time and killing doctor Acno.
