Hmm... I just assumed that the entire fight would just happen on the inside of Acnologia between him and the DS. Until your comment I didn't even consider the possibility of the fight happening both on the inside and the outside simultaneously... a bit like the fight against the Celestial Spirit Beast in the ESC arc, only better. ^^
