A thought...

[WaveK89]

Mainly about Isa. I understand he's one of the 13, but I had figured he was intent on over-throwing the Organization with Lea. Granted, it was the non-true Organization, and his friendship with Lea pretty much fizzled out. I just feel he may play a role in the next game that interferes with MX's plans. Hard to say though if he's already part Xehanort like Braig...

Almost makes me think of Isa as I think of Snape (sorry for the reference). Anyway, I was wondering what other people's thoughts were.

I hope he's like...a spy gone corrupt type, but he will def be a big part in the game if Axel has a keyblade now.

After axel abandoned him his plans must of changed. He know he vant take on xemmnas alone. If you can't beat him join em

Or so it seems.

I think it’s pretty clear what they intend to do with Isa. He's, for all intents and purposes, the Itachi of Kingdom Hearts—the archetypical tragic anti-hero you commonly see in shounen.

Possible Explanations:

A.) He's so mad at Lea for choosing (in his mind) Roxas and Xion over him.

B.) He's possessed enough by Xehanort that he's has been influenced to become loyal to him

C.) He may think Sora's side is the losing side and chose Xehanort's side to save his skin

D.) He is actually pretending to be loyal to Xehanort so he can ruin his plans at the right moment.

One thing I found weird was in KHII when Saix went to Xemnas and asked him if Saix can drop the charade. At first, i took that as Saix dropping his calm attitude and unleashing rage hell during his fight with Sora. I wonder if this line meant something else though with Saix's original plan.

I think A and D are the most plausible options. In 358/2, Saix seemed pretty jelly of the little friendship Axel had with Roxas and Xion.
