Forum:Theatre mode kh2 Remix

Hey I have all of the cut scenes in my theatre except for the final one at the very bottom. I figured I would need to beat Terra but after having done that I still don't have the final scene and was hoping someone could tell how to get it so I can complete the collection. It seems all scenes are unlocked by doing that part of the story which is easy enough but having completed the story I feel like I am missing something really obvious.
