Mr. Tines: Rei is much more relaxed about her dietary preferences than Nadia was. Did Anno mellow out in the interim?
Zusuchan: Nadia and Rei are considerably different people. Besides, Rei's reaction is more Anno-like. IIRC, Anno doesn't eat meat not because of considering it a moral thing to do, but because he simply had no big interest in eating and ultimately meat just fell off the menu. Getting it back would need him to have enough interest in slowly start with consuming meat again.
