What is Tom’s Deal

I will start off by saying that I have no idea who Tom Sandoval is.* But what is his deal? He is acting like an alien who is trying their best to imitate a human. His facial expressions and his entire demeanour seems to be a caricature of what I assume he thinks serious investigators would act like. Couple that with his bizarre eating habits and I can’t tell if he’s hilarious or disturbing!

*As stated - I have no idea about anything to do with Tom, so if he’s neurodivergent or has some type of condition that explains his behaviour, my post in no way means to mock or belittle that.
