Okay, so that's how there are two of them, whatever. Now get to explaining why the real Ciel killed Agni and tried to kill Soma.
Yeah, I hope they explain why Ciel's twin was after Soma and killed Agni because it doesn't make any sense because they done nothing wrong but be nice to Ciel.
The only thing I could think of is that real Ciel knows who are close to our Ciel. And will use them to get him a message? That's usually the case in other stories. You know: "I'll kill everyone close to you 1 by 1 if you don't give what I want" or "Get rid of everyone close to you just for revenge" something like that. And Sohma and Agni just happen to be there.
Hope they give us more info in next chapters, indeed #-.-)










Taichi sure is having fun.
