You know what that's true, in the case for Cid anything he says will be the truth no matter how ridiculous that is and another thing is that he does have the power to back any claim that he says
but Cry is the opposite of Cid, since the truth keeps trying to grab him and keep him in the loop no matter how hard he tries to get out and he doesn't even have the power to back it up
the only power he has being that for some reason truth has this weird obsession of trying to keep Cry in the loop
