Kotomine stabbing in cold blood a soundly defeated Iris, and casually kicking a crippled Maiya was something else... did not really expected it, not because of his character, makes all the sense in the world, but because it was presented with clinical ruthlessness... especially how he treats both as items, which to tell the truth along with Saber and Ilya is exactly what they are Emiya's toys
Talking about Emiya, what a sleazy bastard (know I understand why Saber
hated him in F/SN)... practically poisoned his opponent, after (as Keyneth also said) run around like a trapped mouse...
Which brings me to a question... who the hell was that chick that gave the Rakkyou speech
