So I made a slightly disturbing realisation about Noes past, specifically before his teacher picked him up.
So our first introduction to Noes past comes in the form of Dominique who explains to Vanitas how Noe had been sold on the market as an Archiviste Survivor.
However something that counter acts this is how Noe was found wandering aroind in the human world and had never been to the vampire world till the trafficking incident as far as he was aware.
Implying that the Archivistes were human world dwellers, and the fact that Louis says its still rumoured to be common place for some vampires to take humans to Atlus to sell as labour. Which gives us 2 options.
1. They knew Noe was an Archiviste when they nabbed him.
2. They didn't and found out later.
If we go with the fact of them always knowing then I don't think they ever intended to sell Noe on the markets, that could easily be a lie the teacher came up with, for one i find it hard to beleive a living Archiviste wouldn't be a hot commodity with the vampire population especially given their abilities.
Two Noe implies he wasn't fed everyday at some point.
Three its also implied that he was sold in the human world not Atlus if we take what he says about how it wasn't all that bad, as him speaking about the teacher buying him and not as him realising Domi was on about the trafficking as they were talking about the teacher only seconds before.
Not to mention in chapter 55 we see this breif memory
We see when the teacher first met Noe more clearly with more detail, it could be on audition but given hiw the ground under Noe looks like dirt it wouldn't surprise me if it was actually a circus or a traveling carnival, that Noe was treated more like an oddity given him another connection point with Vanitas.
But the more disturbing part for me isn't the clear damage done to his eye, I think we all talk about that enough, but rather that up close we can see this
Clearly what ever happend him under the watch of the kidnappers wasn't good, but a part of me wonders if vampires were involved could blood drinking of been common for him?
It would explain Noes reaction when Jean appolgised for forcing Noe to drink his blood, that Noes constant 'its fine!' Behaviour isn't just deflection or denial but because Noe truely doesn't understand how wrong what happened to him was because he was used to it.
No one has ever out right told him what happend to him was wrong and he should be upset yet. So far everything has been eaither played for comedy or just breifly touched on, so it wouldn't surprise me if in the next arc we focus more on Noes inner conflict as he comes to terms with hus teachers betrayel, possibly Revisit the death of Louis from a new lense and explore more in depth Noes own inner turmoil about wondering where he actually came from.
Up until this point Noe has been willfully ignorant of many things, and the way he specifically says
In regards to meeting another Archiviste is very clearly a can of worms he is unsure that he even wants to open. What if he gets his hopes up only for them tk be dashes. What if he learns something he doesn't want to learn. What if the Archivistes aren't good people? Or worse. What if some are alive and Noe was actually abandoned?
I don't think thise are question Noe actively wants answered because if he was abandoned he would be forced to Revisit everything he had been through because of that day he was found in the forest.
