Quite frankly, we got deceived!
One of the shocking truths behind the kidnapping of Irisviel is that it wasn’t Rider who actually committed that act. Believe it or not, it seemed rather fishy since he spent most of his time recovering mana and wouldn’t do a dishonorable act like that. Still, it was quite impressive that Berserker had transformation powers as his Noble Phantasm. This can literally trick anyone. From what Kirei had Kariya to do, it seems that he really wants the Holy Grail so badly. On the other hand, this isn’t the only favor he told to him since the tragedy he set up is also his doing.
On the other front, the scene where Saber chases the “real” Rider looked awesome. It felt like a hybrid of Need for Speed and Final Fantasy VII. Even so, her ability to use her powers to instantly soup up the motorcycle to higher speeds looked awesome. While it results in Rider losing his chariot as she uses her trump card, watching him and Weaver say some lines was enjoyable since their appearance got reduced in the second season.
As most guess, Kirei purposely set up Tokomi’s death at the church so he can lay the blame on Kariya. From there, the following events that unfold between him and Aoi getting upset over the actions he done felt emotional. When I saw her putting all the blame on him and accuses him for not loving anyone, it felt more like a Shakespearian Tragedy. The problem I saw with Kariya is that love, jealousy and revenge blinded him. This causes him to strange his love interest. In addition he lost his original focus of saving Sakura from the Matou family since he wanted to kill Tokomi. Even so, he could have prevented it off the bat had he became a magus a first place and forgot about Aoi. Not only that, he never let her voice what she thought about the whole thing before diving in. I suppose Kariya should be happy now since he effectively gave Rin to Kirei as her guardian.
From the look of things, I think Kirei purposely set up Kariya’s tragedy just for the sole purpose of enjoying his suffering. As shown in Episode 12, it’s obvious that he had some interest on Kariya’s situation, which drags him back to the war. He seemed to enjoy it although Gilgamesh finds the whole thing as a “terrible play” from watching it at the balcony. Knowing him, he might end up reviving Aoi just for the sole purpose of watching her suffer from not remembering her husband and Sakura. Yeah, nobody can match Kirei’s level of evilness, except for Zouken since he is scum of the earth… although both agree on one thing: they love suffering. ¶
