You were arguing earlier that her hair and eye color weren't possible in the human genome as part of why she's supposedly creepy? I'm willing to chalk it up to "lolz anime", but you can't.
I said nothing of the sort. What I actually said was "She has bright red eyes and blue hair, which is weird
." Red eyes are certainly possible in the human genome -- see albinism, as well as particular shades of brown or gold that amount to the same thing. Blue hair's more problematic, but that doesn't say anything about how she's constructed.
Does she eat? We know she CAN, but we don't know that she does so typically. I don't recall seeing any food in her apartment, just pills.
She has a kitchen there, so her food is presumably put away. Most people don't have food laying about, after all. Also, given the amount of time she spends at NERV HQ it's entirely possible she rarely, if ever eats at home.
She's hinted to be infertle, which could be evidence of her inhumaness. Not that infertillity isn't possible in humans of course, but it's considered a flaw for us but seems to simply be the norm for her. (well, unless you buy into the ultra-fertile argument... but that's still not normal for a human).
I don't think there's any explicit commentary on the subject either way. She's "a woman who doesn't bleed"; that's all we've ever heard on the matter.
(note that Lilith bleeds quite a bit; if we're saying she's supposed to be made of PWM because she's like Lilith infertility is not a great example in support of the argument.)
It's closer to whole than it was the majority of the series, and I don't recall Rei casually losing parts before that. There have been several idea put forward about why this happens (different thread), but I don't think this idea of yours is a viable contender.
We haven't seen her that close to Lilith outside of an Eva before, either. Regardless, as you say there are several options apart from "she must be made of PWM!"
We assume that because they act like angels in the sense of crazy otherworldly powers. Lilith-based life was created through a long process sepearated many, many layers from Lilith herself, so it's much more reasonble to say that we'd be different than angels that came direct from Adam, possibly even created directly from Adam's blown apart flesh.
So, what, our progenitors were PWM but over the course of time became normal carbon-based life? That's more of a stretch than the alternative. And I'll note that Ritsuko never says anything about the Evas being PWM. If they're clones of Adam and they're not PWM why would Adam be different?
The little dangly legs and a tank full of clones tell a different story,
Not really. The clones in the tank could just as easily have been created after the fact (using the same process that created all the other Evas), and the legs aren't specifically Rei any more than anyone else. Lilith is the progenitor of humanity; I'd expect weirdness like that even if Rei had nothing to do with it.
Yes, but it means it's coming from Rei1 (the one who actually remembers all this shit being done to her), so that puts the crazy squarely outside of Rei2... and thus the Rei I care about still isn't creepy.
How do we know what Rei I rememers, or that Rei II doesn't remember same? The specifics of the memories retained from one incarnation to another have always been murky at best.
On a related side note, how do you understand Israfel? Is it it one being with one soul that can split into two halves? Is it two beings with two souls that can merge? Is it one being with one soul that can become two beings with two souls?
The first, though I'm not sure how that's relevant. As with the PWM business the fact that an Angel can do something (and Angel with an S2 organ and a core, no less) has no bearing on the case of Rei.
Now, what implications do your answers there have for identical twins (split in mid-development from a single zygote) or for the various forms of Rei?
Eh? Identical twins separate physically early on and get souls just like any other human (heck, the presence of two souls might be what prompts them to become twins to begin with in the Eva setting). Again, I don't see the relevance to Rei's case. Remember, the Chamber of Guf was empty hen she was created -- getting a new soul wasn't an option.
(How do humans manage it? No idea. But they do, somehow, and whatever they do is explicitly not in play with Rei.)
