Irene was Erza's imaginary mother who somehow materialized! No just kidding.

At least the mother/aunt/sister theories are out of the window I guess. Maybe Knightwalker after all, though it would be strange for someone with no inherent magic to suddenly be among the most powerful wizards alive. Maybe another paralel world? Let's hope not.

Something farfetched: Irene was constructed from the eye the Zeref cult took from Erza and this eye contained most of her magical power. As Irene uses magic but no physical combat, while Erza uses close combat and not so many true spells. After all, Irene activates the "sky eye spell" with the eye that Erza is missing. I'll admit this theory is based on the Kakashi/Obito eye sharing, but can't think of anything else that could make sense.

However, I do have a feeling that regardless what explanation they give, I'll end up thinking "ridiculous" and "bullshit".

August finally demonstrates some of the magic he knows, seems he has all the abilities of the CS peeps. Somehow, I believe it will be boring or fought off-screen.

Just have Acnologia rip the old man apart.

Glad the bitchfight between Gray and Natsu is over, I'll even tolerate the flame pants and nakama speeches.
