Damn, that was good. The first part played well against the last by making such a strong contrast between a peaceful life and what they had to face in battle. And what a battle! Heathcliff finally shows his abilities in a boss battle and Kirito and Asuna were awesome together. Leaving it hanging like that wasn't fair though.
Now I've got to wait a week to see the ending.
Asuna is becoming more and more one of my favorite heroines.
