>>2167942In NGE it was Ikari Yui because there you had some backstory with Gendo and Yui. In Rebuild, they've cut that backstory and just named Yui "Ayanami", in an attempt to make a hiearchy where Rei inherits from Yui more.
It's really that simple - Anno, Tsurumaki, they have no interest in Rei as her own character, and by tying Rei to another character instead of letting Rei be her own thing like in NGE, they neuter the character so other characters can become more prominent.
It's a really simple solution to your question, and it's not a good thing. Take this:
>>2167949which isn't true since Rei isn't a distillation of Yui's essence until now in the Rebuilds, and we don't know a single thing about Yui to say either is superior, but by default Rei will be inferior and that is the intent.
The opposite is happening, Rei is being brought closer to Yui, instead of being crafted as her own thing. Taking the musical example, it would be like we started with the two different but similar melodies, and cut away at one of them until they resemble each other completely.
Because of this, Yui now has Rei's canonical surname.
