It wasn’t the show. It was that anon was kind to him and wanted to hang out with him, be chill and connect with him with sincere good intention, and that made such a profound impact that he didn’t want to let it go and wanted to go deeper into whatever was going on in that world.
Anon is mistaken about the "stutter" though; it sounds more like palilalia. Both of which have a low prevalence rate (<10%) so it's weird that anon calls it "classic."
