Fuck it. I'm still hung up on the idea that Shirouzu Char might be CCA char.

Putting aside the scar issue, which blows a big hole in the theory, he's remarkably chilled out.
This is the kind of thing I'd expect a post-CCA Char, who "saw the light of the human heart" Amuro wanted to show him to say.
He says this after Kycilia asks him if he would genocide humans living on Earth for the sake of the newtype dream.
Even if it is just GQx Char, this is a very different Char than one we've known.
