Yeah, I'm just gonna hardcore HC him as autist- like, even when he's conversing with others (through his native language or through dreams), the way he speaks seems to be tilted. There are times he's speaking fine, and it's like, it's hard for him to convey something that 'everyone else' might find super easy to state and convey. I really see a lot of his behaviour quirks as very much like my own- and, like Lalli, even if I'm like... talented, at something, I'm not a savant at anything. For the most part, I seem 'normal' to most people, if a bit blunt, harsh, or straight to the point, or have difficulties finding ways to communicate with people, even when we're speaking the same damn language to each other.
The trait I liked the most with him, was how he covered his ears- when I'm incredibly overwhelmed (for good or bad reasons), I tend to cover my face with my hands completely, and curl away from the source of what's overwhelming me.

Also, I've kinda noticed that people like me tend to mimic animals, especially cats. Part of the reason I was asking was, I was afraid that maybe he was 'like that' because he was just basically being portrayed as a person with catlike responses and features. It's nice to know that there's room for him to be more than just 'weird catlike magic dude', and that the author openly left room for him to not just be a play on how 'he's basically like cats in this world'.
He's definitely my favourite character, and I can't wait to see more of him, and his interactions with everyone around him.
