I'm just guessing btw but prob he said those things about Nora in the heat of anger and with the humiliation he suffered still very fresh. Plus their strong view of them and Nora being friends regardless of social difference just hit them and no ulterior motive just shattered. Doubts and "I was a fool for believing we could stay friends even if we are different" is def there. When the other kid mentioned hero and etc that prob triggered a sore spot on him who prob cares deeply his dad.
If we use real life story (wwi) war's survivors esp poor ones aren't treated like heroes but rejects or burden since they can't work etc so I wonder if there's a strong resentment he secretly holds for how his dad had been treated being invalid bc of his injury.
My point is that its not just jealousy.
Nonetheless, my point was my dude isn't a good friend if his first reaction to unfairness is not to blame society, Nora's grandfather, Nora's father, mans blamed Nora himself and that's disgusting. No matter his emotions, what I don't understand is saying that to someone who's supposed to be my childhood friend. It's also shown later that Hans goes off of Nora when he sees him in person, so it's not only heat of the moment anger/humiliation. Ig what I'm trying to say is idc whatever emotions he was feeling, what he said is by no means justified.
Sorry but I don't understand Hans at all. Idc if he's jealous, blaming Nora for his own abuse is the lowest of the low especially because they were friends. Also is Nora's father finally understanding that he lost his son? I'm kinda hoping there's no redemption arc for him.
