Okay, maybe it’s because I have ADHD and I like seeing fictional characters that are like me, but hear me out here.
-He has mild inattentive type, more commonly known as just ADD, (no hyperactivity)
-It’s mild, so he doesn’t NEED medication, but maybe he should. He’s not going to though. I’ll bet he hasn’t even been diagnosed.
-Absent-mindedly touching the inside of a high voltage broken machine while walking in? That’s something I would do.
-Hyper focus would definitely help him while fighting.
-He’s really smart but gets bad grades, even when he studies. He finds studying subjects he doesn’t like to be really hard. See: Teacher of the year
-He seems to overreact to some things and has pretty strong emotions. This doesn’t happen with everyone that has ADHD, but it can be an effect. He screams a lot even when he should be used to what is happening. Call me crazy, but it feels like Tucker and Sam are a lot less vocal in battle than he is.
-I don’t think he means to let Sam and Tucker take a lot of blows and let them take the blame. I think he just has slightly less impulse control than the average person and isn’t good at thinking consequences through.
-ADHD can be hereditary and if you think there is absolutely no possible way that Jack has ADHD or a similar illness then I don’t understand your logic.
-Also there’s that theory floating around that ectoplasm is mildly radioactive and/or Maddie being around it while pregnant could have some kind of effects on her kids. This could have led to Danny having a slightly underdeveloped prefrontal cortex, which is what causes ADHD.
-He’s bad at dodging. I too have spaced out during situations where I should have been dodging and either saw the thing coming at me and for some reason didn’t move or just didn’t think about it and got hit. However, when I’m having a good day I’m really good at it. That’s how Danny can honestly say he’s “a whiz at dodgeball” and still get hit as much as he does.
-He’s really smart but misses obvious things. He also thinks out loud a lot. This is something my brother and a few other people I know who also have ADHD do as well.
-A lot of people with inattentive type (including myself) have a hard time making and keeping friends. Will often have either no friends and a few acquaintances or one or two really close ones.
-If you believe the trans Danny headcanons, that can explain why he hasn’t gotten help yet. It’s a lot harder to recognize and diagnose ADHD in girls and people that were socialized as girls.
-He comes up with puns and insults on the spot. Neurotypicals can do that too, but when you have ADHD, your brain often makes seemingly random connections a lot faster than the average person. This helps with making spur of the moment puns and solving mysteries. Remember how he figured out Spectra was a ghost?
So, yeah. That’s my reasoning. I just honestly think that him having ADHD clears up a lot of things about his character. But, I’m not a psychiatrist. I’m just one guy that has ADD. This is just me speculating.
