I finished all of Fate/Zero today. That ending was so unexpected! So I am guessing the grail can't be destroyed? And if you reject it, it goes to the runner-up, which is why Matou won? Or did Archer win, because he materialized as a human? Should I watch Fate/Stay Night next? I have heard there are other animes to watch tho before F/SN like unlimited blade works or something.
