Creepy stalker guy...

.. I'm expecting Asuna to quit her guild one of these days if this keeps up. Partying with Kirito should be enough to show her that's going with a guild is not the only way to play with support, and likewise for Kirito.

I would have cut that guy up in the duel. Since you supposedly can't feel pain, it doesn't "hurt" to do it. He won't have to pay for a new weapon neither. It'll also mean that he's got to stay inside a town while he heals himself (unless he goes to purchase healing potions), so he'll be out of the way of the date as well.

Plus.. there's no blaming the weapon and all. Sometimes trying to act nice and honourable just isn't as good as giving a clear backhand to the face.
