Okay, at the end of the game, Squall witnesses Edea accepting Ultimecia's powers. So Edea has Ultimecia's powers. Later, Edea becomes posessed by Ultimecia(which is in the future, but Edea still has her powers) and then the future Ultimecia posesses Rinoa (which never actually accepts Ultimecia's powers) but Edea is posessed no more (is she still a sorceress?) . Um, I just don't get it.
