@FirstAnon: You'd be right if this was Brain we're talking about. But Zero won't co-operate with anyone. He's a dude that loves total destruction. That's why they had to seal him in the first place. Midnight is smarter than that. And if that really was his attention,he wouldn't be so understanding with Hoteye regarding his decision not to fight. That just increases his chances of getting caught. Midnight seemed really rehabilitated but he's not the only theory going around. Jellal is a fast learner who learnt Mystogan's magic in under four days. Who's to say he didn't learned any Illusion magic?(Which is a part of Mystogan's arsenal) But I still bet my money on Midnight and Jellal himself using Thought Projection.

If your theory is true,the OS will either have to fight Zero or fight among themselves. And this is the Tartaros arc. Why would Mashima go to such length with OS and stuff that doesn't concern the current plot at all? I say this is a ruse to fool Tartaros.
