I was listening to the soundtrack of Eva 3.0, and reading the lyrics of "Betrayal".
Once friends betrayed so ruthless
Now dead his friend and friendship
Once friends betrayed so heartless
Memories crushed to ashes
I guess this is a reference to Kaworu and Shinji's friendship and betrayal. But this seems to make more sense in the context of NGE, and not Rebuild. I don't see how Kaworu betrayed Shinji in Rebuild. At worst I would say he wanted to help him but got betrayed himself. Could this just be a change in script that took place after they had already writtent he song? Or am I missing something?
