You may not know this since you're a new user but that actually was one of the two original scenarios for EoE's ending. Grimdark, disturbing shit, even by EoE standards.
Manga has been so-so at best for a long while (nearlyimmeaditly after the very first volumes with wich Sadamoto did good job IMO), it's just that it looked like:
For the longest while: Sadamoto's Reifaggotry and Rei-Shinji shipping is the rule, Asuka marginalized
Later stages: Asuka gains central prominence and becomes the most likely pair candidate for Shinji, Rei as romantic interest withers away very quickly
Now: YEAH LOL NO, there probably isn't anything even remotely romantic between Shinji and Asuka after all.
Both Rei and Asuka are pretty much "out" at this point sans weird, stupid Sadamoto bullshit I'm sure he has in sleeve but which I can't predict.
Well, the manga is weak either way so I don't really care apart from "I wonder how Sadamoto is going to screw up things next" factor... though even then I fear he climaxed with Gendo's hand AT Field...
