Ahh…Kirei…what have you done? Poor Iris. I wonder if this is meant to send Kiritsugu into a rage, so that Kirei can crush his idealistic wish to end war with the Grail. Also, Waver and Rider…bros for life. Waver looks a lot more like a main character by befriending his Servant and then making it so far despite how weak and timid he is. Those two are still my favorite combo.
The stage is set for the final battle. The preview sounds like Rider versus Gilgamesh. Also, Saber will likely face Berserker and Kiritsugu will face off against Kirei. It sucks knowing the outcome, but I hope the battles end up being exciting anyway.
