Guys I just had a complete Shellstrop style āholy motherforking shirt ballsā moment at work about Donnieās unusual speaking patterns. You know, when he does this:
This tendency to narrate his actions in the third person or verbally say onomatopoeias in place of the sound is uh⦠well itās autistic right? Look it features in literally every compilation but no one knows why other than āvibes, sometimes it just be like that š¤·ā
But NO. No it NOT be like that. I finally know what this fucking nerd is doing, hear me outā¦
Think about it. You know what else describes action, emotion, and sound in purely words? Books. He has these little speaking quirks, yah, but if you actually zoom out and see the whole picture, Donnie talks like heās a narrator. This makes a SHIT ton of sense considering we already have textual evidence that he engages in scripting behavior (more specifically some possible echolalia. See: saying āNew York! What a Town!ā in any situation something kind of abnormal happens after he hears Splinter say it with the exact same infections and everything.)
And we also know from the mystic library that Donnie actively seeks out and enjoys reading. So it stands to reason an autistic 14 year old who likes to be left alone to work on complex machines a decent amount and takes pride in his intellect would model the way he communicates off of written media as opposed to tv or his brothers. He could fill his social tool box with lines from Jupiter Jones and Lou Jitsu movies, but he may think it would give him less of a chance to properly express his capabilities.
Books are also the only form of media that can literally just tell you flat out what a characterās expression or emotion is supposed to be without it being awkward, which would be really appealing for Donnie. What solidifies this for me is the fact that at least once he verbally says āsad face emojiā, which could not have come from a novel or textbook. But we often do flagrantly use emoticons as tone indicators, and Donnie is constantly on his phone.
I think heās definitely aware that this is not a regular way of communicating, but heās clearly also self aware of his issues in getting his emotional meaning across and receiving input back. So it stands to reason he would accommodate this in a way that, yes, makes him sound odd, but is at least effective.
Now for my final little āIāve connected the dots. Iāve connected themā moment, I headcannon that Donnie learned to read before he fully got the hang of speech. Aside from⦠literally everything I just said, he uses sign language to tell the squirrels to blow up his treehouse in that one episode. But he does the sign for āmakeā a bit incorrectly (there should be a slight twist in his upper fist), which leads me to believe he was probably taught baby sign out of necessity rather than being fully proficient in asl. This is fairly common for autistic children with speech delays.
