I don't think Caelus would have tried to frame Kanda if he wasn't possessed either, but it doesn't change the fact that he did. But he had a reason to be mad at Kanda, so maybe the monster aggression exploited that or whatever.

[he says it matter-of-factly though, then]

M'not gonna speak for Yuffie -- [she has the right to feel however she wants to feel about you guys and Camille] but Kanda won't be like Caelus, possessed or not.
