I think the most epic scene or more of a bad ass scene, would be when Asuna jumped in front of Kirito and died for him and he used her rapier. Then Kirito managed to defy death and defeat Heathcliff, or Kayaba Akihiko. I still do not fully understand why they were brought back to life by Kayaba Akihiko... but I do know that I don't care! haha. The end when Kayaba gives Kirito the world seed is awesome because that meant there would be more sword art!
That's the scene I thinks is epic, what do you guys think?
