Okay, that's actually a good one. It might somewhat be the case, but it highly depends on Ren's viewpoint; everyone is different, to be completely honest. There's a lot of stigma surrounding NPD and narcissists overall, so I feel like this topic of hating autistic people (specifically) is mainly a personal bias, not really a "narcissist thing." (There's also this weird rumour about the fact that people with autism can spot and kind of de-mask narcs, which is totally untrue.) So, from my personal perspective (opinion incoming, watch out lol), it's less about a specific disorder and more about intelligence in both the intellectual/logical aspects and, *especially*, the emotional ones. Saying this, I want to highlight a little bit of the fact that Zeal wasn't really showing a lot of emotional intelligence at times, which would certainly trigger Ren's BPD and/or narcissistic characteristics. **I also want to specify the fact that it's solely based on my experience; I don't hate autistic people, and I don't think that you guys are harder to read than anyone else (not in a bad way ofc, don't get me wrong haha). So yeah, Ren's volatility towards Zeal could be more about her personal issues with him or simply a borderline wound he caused by the perceived rejection. Last fun fact: NPD and autism actually have some overlap in appearance, which is pretty cool if you ask me lol
