A pretty episode. Excalibur sure got some visual effects boost compared to the old series. Gilgamesh's obsession with Saber we later saw in FSN is growing nicely.
Somehow I can't help but feel that poor Tokiomi is the one the most out of everything in this show. He thinks he knows the most, likely, but in reality Kirei is working behind his back following whatever ambiguous goals he has, his own servant couldn't care less, and he wasn't even interacting with the others in this cooperation battle. Kariya is of course another matter, but he's pretty much as berserk as his servant, so he's living in his own world of madness. Well, now that Caster is gone, things should go back to normal. I hope we see something smart from Tokiomi.
That was my first thought as well. It would make the most sense, since it used to be a fighter jet.
