Looked to me like he was on his way to north... We have Gajeel, Sting, Rogue and Cobra there. Sounds like the perfect place to continue DS massacre.

And that's what leads me to believe that Irene will actually be able to do something to Acno, at the very least, stop him for the moment. I doubt Acno will kill any more dragon slayers, Cobra perhaps, but the first and third gen shouldn't be touched since they are the original 5 chosen to eventually defeat Acnologia.
