I have a machine i have made to keep out spiders. I write on the wood "abra kadabra." That wood i call Apostle Sealing curse pattern. Now what im saying is this is a pattern that seals out spiders. "abra kadabra." is the seal however it is comprised of individual letters a.b.r.a ect and thoes individual letters are the glyphs. I then get an eye patch and i write 'eye' i have used the 'glyphs' but that does not mean that it is a seal against spiders.
There is no proof that the individual glyphs are seals against angels, the best you can come up with is some possibly correct translations and what someone else has decided to interpret that translation as with nothing really to back that than pure opinion. However in the ACTUAL film you see that each glyph actually represents a letter. I have no idea how you can go, oh there angel seals AND someone decided to give them a 'fancy' alphabet meaning too!!! I mean how do you get that?! fanboy opinion as a priority over evidence presented within the film itself?!
Are you kidding? simply put BECAUSE ITS EVA?! why did Ritsuko mouth something to gendo at the End of EOE? for half a second that Anno went to the trouble of putting in?! Its what he does, all the time!! Its not even like the runes where made just for EVA to be angel seals he lifted them directly from Nadia secret of blue water!
Truth be told, outside of some obscure religious symbolism, most of the smaller details in Eva have a meaning, one way or another. Stuff like the mindrapes and whatever Gendo said to Ritsuko in Eoe, may not be explicit or clear and leave the chance to the viewer to come up with a personal interpretation, that cannot be proven (indisputably) right or wrong (within certain boundaries...) but they are mainly relevant to the characters and not to the plot itself. It seems to me like the entire thing with Asuka's eye has been set up to have actual relevance to the plot and not to be some kind of easter egg.
Gonna try to list the hints that there may be something angelic in her (gathered from the discussion):
-In 2.0 we can see that Asuka's left eye was wounded after the Bardiel's incident, seemingly implying that whatever happened to her eye is connected to that incident (which involved an angel essentially talking control of her).
-Still in 2.0 (if i remember correctly) Ritsuko states that Asuka's mind may have been corrupted by Bardiel (even though she was physically all right).
-In 3.0 when her eye glows, it does so in a cross shaped, blue colored, pattern. Shape and color usually associated with angelic beings in Eva.
-Still in 3.0, it seems like runes appear on her eyepatch. Runes that seem to have been designed to seal angelic "powers" (ofc we can't know that for sure).
-The new plugsuit she wears has some weird details in it that may have something to do with her new condition:
The "core" of the plugsuit is blue (angel color) unlike everyone else's plugsuits (Mari, Kaworu, Rei and Shinji) that have a red "core".
The two parts of the suit in the chest region are of different colors (once again, something unique to Asuka). Both colors are used to indicate specific blood patterns in Eva (orange and blue). Link to the wiki article http://wiki.evageeks.org/Blood_Type.
-She breaks a thick glass panel (in a battleship) with a punch...
-She grows fangs when she goes in beast mode (i'm pretty sure Mari didn't, in 2.0).
(The last two points may have nothing to do with the incident and may simply be explained by the "Curse").
Add to those the fact that it seems to be quite likely that Asuka will get more screentime in 4.0 and that an angel contamination could easily provide some effective drama and, from my perspective, it would be very weird if the eye turned out to be a red herring. That said, it's true that there's no way to know for sure, but let's not even treat the "Asuka has been contaminated" theory as something far fetched.
