Makes me wonder how, is it gonna be a inner battle against a second personality or will they somehow split apart and then fight each other.

I like the former because that would make the fight seem more epic as they'd lack Natsu who really kicks butt when he gets serious. Having him stay within the mind of END means he can only fight him mentally, and unlike the Dragonoid getting mad's not gonna free him.
