Do you think Kit Herondale has ADHD? and do you think that because Ty is autistic, his POV is very different when he writes?
I guess I'd say that if you as someone with ADHD relates to Kit, that is cool. Like I said, there's not a wrong way to relate to a character. But I didn't write him consciously as someone with ADHD because if I had I would have done what I did writing Ty — months of research and not writing the character without consulting with sensitivity readers who themselves were people with autism. I wouldn't have felt I was doing a character with ADHD justice without doing all those things.
I do think Ty's neurodivergence would impact his narration of a story, yes, so I won't be (and am not currently) going to be writing any parts about Ty (whether he narrates them directly or not) without multiple sensitivity readers consulting before they're edited. That is why you have not seen much from Ty snippet wise from TWP. I would not even want to post a first draft publicly without consultation, given the possibility of hurting or upsetting someone with representation that doesn't feel right.
