I really like how the author write Shirou, as we get to see why he is motivated to do the things he does and what he is thinking, which is more fun in my opinion than the silent protagonist. And the people around him, the side characters also has such unique bond to him, which is nice to see too. But the build up in this episode is what makes it shine in my opinion, especially towards the end. I'm so pumped for the next episode!
