I was looking through the "Fall of Shuyin and Lenne" captures (at ffshrine, of course), and I never recall seeing a scene like that at any point in the game. I was wondering if the scene was from a special copy of the game, or whatnot. I have not seen any information on any other site about this scene, and it bugs me.

I was up all night pondering over this, I'd love it if someone could help.

You see these scenes during the 1000 words concert. You also can see some of them when you enter the Den of Woe.

In order to get it on Shinra's spheres, you need the Den of Woe scenes. And you need all ten Crimson Spheres to activate that in Chapter 5.
