358/2 Days Illusions?

Spoiler

In mission 88, the Organization tricks Roxas and Xion into fighting, each thinking the other was a giant Heartless. How is this possible if the only one in their numbers who could create illusions (namely, Zexion) died in Castle Oblivion?

 

I have some ideas:

• Since Xemnas absorbed/adapted the powers of fallen members in KH2, maybe he did the same with Zexion. But that would then pose the question of "Why doesn't he use those powers in KH2?"
• A Nobody machine. Marluxia had his flying thing, Xemnas merged with a dragon-thing, who knows what other technology Nobodies have to use.

Either of those sound plausible?

 

Hmm...maybe it was something similiar to their holomission technology.

 

Or perhaps one of Zexions nobody minions, with similar powers to him? I know what you're thinking: Why didn't they appear in the game or KH2?

In Days, the only Nobodies are fought during two missions (Dusk and samurai) and the escape mission. The CO members had very little screentime in the story before dying, so we never saw them commanding their minions. But we know that these minions can still be controlled, because even after the corresponding Org. Member died in KH2, they were still under the Org.'s control. Perhaps if a Nobody dies (Or deserts in Axels case- his assassins attacked him, remember?), the control defaults to Xemnas. Xemnas then assigns the 5 CO minions to covert work, or perhaps the running of the castle behind the scenes. So Zexion's minions may have been available to cast the illusion, hidden behind a grave or something.

 

Do Nobodies have minions? I thought the Organization was just powerful enough to control the lesser Nobodies, and maybe they knew better than to follow Axel, seeing as he was a deserter. If they had specific minions, couldn't they have helped us in missions? And even if they DO have minions, are their powers the same? I don't think they are.

 

Xemnas- Sorcerers
Xigbar- Those sniper ones whose names I forgot
Xaldin- Dragoons
Axel- Assassins
Saix- Berserkers
Demyx- Dancers
Luxord- Gamblers
Roxas- Samurai
All: Dusks and creepers
Dead CO guys: ???

Notice that several of these have similar reactions to the boss fights of their Org. Members. Eg., Luxord and the Gambler both have the card game reaction command, and Sora can wield the claymore of both Saix and the Berserker in the same manner.
