I'm sorry, but I can't see where you're going with that. A woman depicted in a stained glass window created 3000 years ago in Rhuidean means the flesh and blood killers in the Epilogue, moving in the familiar Aiel crouching lope, with short hafted spears strapped to their backs, wearing veils (albeit red ones) aren't Aiel because they both have black eyes? If they aren't Aiel, they do a good impression only spoiled by the lack of blue or green contacts. If anything it shows there were embarrassing errors even in TFoH, the series' best book, (assuming THESE dark eyed Aiel aren't an error) but I choose to chalk that up to Rands ignorance at the time rather than Jordans (AND HARRIETS) sloppiness. Pale skin means you can't be Aiel? Looked in a mirror lately, Rand? Presumably he realized by the end of the book that pale skin isn't that uncommon among Aiel; he certainly saw enough of Aviendhas pale untanned skin. Brown eyes should be even more common, since the gene for brown eyes is dominant.

If it looks like an Aiel, lopes like an Aiel and wears a veil like an Aiel, in my book, it's an Aiel. Something hinky's definitely going on, IMHO; it might be an oversight if Sanderson just mentioned the fangs during the killing, but that the Aiel BEGINS veiled, we're specifically told he removes it and THEN Barriga is killed argues there's more going on than that. I don't recall Aviendha veiling to kill gara lizards or the snake Rand encounters in the Waste, so MAYBE these new Aiel consider Borderlanders, Wetlanders or just Lightsiders such low forms of life that they're animals to be hunted rather than humans to be killed. It might be as simple as the Aiel who joined neither Rand NOR the Shaido after taken by the Bleakness renouncing all traditional ways that have no MORE than tradition to justify them. If the origin of veiling (to conceal the shame of abandoning the Way of the Leaf) has become common knowledge those unwilling to give up the Way of the Warrior may have discarded the practice entirely, but retained the veil for its functional purpose in the desert Waste. I think they're undeniably Aiel though; not veiling raises more questions about that than their eyes do for me.
