It's
this one. You can tell that it's going to end badly by looking at the title, but it's just done so well you forget it... It goes great legths to line out just why the two are so perfect for each other and how the comon misconceptions about the pairing just don't apply... and then comes the big revelation, and everything goes STRAIGHT TO HELL.
Magnificiently.I must say that some parts involving Gendo feel a little contrived (then again, the premise sort of demanded it), but otherwise, it's an awesome read, (the style is great, it has little details like the Tv programms in the background hinting at the story just like in the series) no matter wether you support R/S or not. (If you don't, look forward to the tragic conclusion, if you do, well, its simply an agle that is there and is interesting to see explored for a change...)
the worst are, besides the afore mentioned breast juxtaposion, the little hope spots towards the end, where Shinji seems to be getting over the initial shock, not knowing that, well... yeah... the basic idea behind it was to do an evangelion version of the basic oedipus story, and you know how that ended.... Still, its definitely an idea that needed to be done.
