I only saw his introductory episode, but yeah, to me he seems too stereotypical. But that usually is the case with ASD characters I have encountered on TV.
On the topic, one thing that really bugs me is that every single ASD character I’ve seen (which granted I don’t go super far out of my way to see) has the stereotypical interests/talents. For goodness’ sake we do not all like trains and/or math and/or math-heavy science
I always related most to Fern.
