Best chapter in months.
This seems a lot better than Irene's story. I just hope Hiro won't screw up this one. I'd be ok with 2-3 more chapters of August (or even more, if they want to use him against Acknologia) if they make him properly interact with Mavis and/or with Zeref somehow, and he actually contributes to the story, not just die in a sh*tty way.
For example Mavis could give a bit of love to her son, who could help in killing Zeref and Acknologia(love/nakama power, lol). Or Mavis gets killed by August while trying to convince him. I can see many good outcome. It's up to Hiro though.
