Do you want me to show you the FMV of CC where
(SPOILER)Cloud toss Sephiroth in the Mako?
And do you think I need to use spoiler tags to talk about a scene in CC, that is exactly the same scene of the original FFVII, but that is considered "a new scene/recton" now, only because of LO's previous recton?
About Ultimecia, I agree her past wasn't explained in details. But Zemus' past wasn't too. Kefka's past wasn't either. And etc. The point is: Ultimecia have a good(and sympathetic) motive for her actions. And that's enough. Details aren't allways important.
But fuc*k that. Lets just agree to disagree and be over with it.
