Okay, so, I know I am stupidly, obscenely, unforgivably late to the party on this, but I want to say...I like it. First thing I noticed and appreciated was the non-linear timeline throughout. When you have extreme emotions toward someone, when you love someone, things are fragmented at times and you can be in so many different moments at once. So, props to you, Alex, for nailing that.
Kaworu spoke up. "Heh, Hikari can be quite scary when she wants to be. The way she puffs up when she gets agitated is quite fascinating. She is like...what are those birds from Australia?"
Touji was confused. "Are you calling my fiancee an ostrich?"
Kaworu waved his hands in defence. "I don't mean to insult... I mean she is a very pretty ostrich."
That bit was hilarious.
And more seriously, I'm thinking visually here and the visual you created for Asuka, Shinji, and Kaworu in the future, it reminded me of one of those classical statues that's cracked in a few spots but still beautiful. Because that's kind of where they are at that point. I hope that makes sense and doesn't sound pretentious as all hell.
If you ever did more with this, I would like something where Rei asks about his namesake and his parents tell him.
