I have come to the relisation that i don't have to complete the game - You Tube perfectly spoilt my 150+ game. I also was disappointed (especially with You-tube, it was in spanish, dammit) but i thought nothing on it, other than, "Why, oh why couldn't they just have them both die, which would be perfectly circular logic, leading back to the spiral of death that spira is based on."

And it has since come to my knowledge that if you skip a scene (purely for the fact that you are fed up of the banter) you don't get the added % complete - so i could well have seen the 100% complete ending on my own 10" screen had it not been for my impatience. My Bad.
