I'm not too sure if this has ever been brought up but it always intrigued me how during "re-enactment", for a lack of a better word, of episode 15 during Instrumentality in EOE, Ritsuko is clearly heard in conversation involving Asuka, Misato pertaining to the later's sexual escapades with Kaji. Yeah, I haven't watched the series in a while and all I remember is Shinji looking disgustingly at Misato and Kaji going at it, Misato say something about Shinji not knowing the real her, Asuka commenting about adults licking each other's wounds (or something to that effect) and Ritsuko, THE ONLY TIME we ever hear her or get a hint of her presence, says that it's nice to be feel wanted/needed, assuming the English translation is correct. It's interesting because it more or less alludes to her relationship with Gendo and her yearning for intimacy, physical that is. There's a theory that Gendo actually said to Ristuko, before he offed her, "I really did needed you". I'm not too sure if that's the case but it's a interesting possibility and it would tie with she said, again, assuming the English subtitled version I'm watching is true to the original Japanese. But my ultimate point is that even with that one line (or two, can't recall), SHE'S there in Instrumentality with Shini, Asuka, Rei and Misato, that is, before the official tanging.
Perhaps people have brought it up but in all the threads I've read here on the Eva forms while lurking I don't ever recall any mention of her lines/presence in Instrumentality within EOE.
