Everything seemed fairly in line with the anime this chapter. Shinji got destroyed by that angel. I always really liked the design of this one, being a giant blue diamond-shaped....thing.
Instead of a slap, Rei hits Shinji with something even harder: "The only thing in the world I believe in is the Commander." Suffice to say, he doesn't know what to think of that. And, it looks like things went bad at the end.
The fact that Rei knows something about his father so as to trust him so much is pretty much way harsher than a slap on Shinji's face. Then to make matters worse, he gets sniped by the 5th angel. Good heavens.
