This is a shounen gangan scan as it appeared in the magazine. Pay attention to the center section. Here it shows Xemnas the Superior speaking.

This is the same scene except the middle section now shows what looks to be Xaldin who is crossing his arms, Xemnas to the left of him, Xigbar below him and Saix is the one gripping a cup with a spoon.
Shounen Gangan scan 2
In this scene you see the Organization sitting on their thrones where Nothing Gathers, but look at the bottom scene. These are clearly words from Axel.
Kingdom Hearts II Volume 3 Chapter 19
This is the same scene Where Nothing Gahters where you see Xemnas at top, Xaldin to the right, Saix is covered up by a word bubble, Demyx slouching, the back shot of Luxord, and a slight sighting of Xigbar. Xemnas is clearly speaking of Axel and what will happen to him if he returns to them.
At the very bottom though you now see what looks to be a book with a bookmark, a jar of some sort and a bottle of some substance where previously there was nothing there except words.
Kingdom Hearts II Volume 3 Chapter 19
In this version you see Xigbar ( I assume) who has avoided a blast from Xemnas. Notice you see his feet and the blast mark on his throne.

This image looks to be a image of Xigbar (I think) speaking to Xemnas whom blasts him. Notice the center image. In this one you see him sitting *close up* version of him.
