Charlie has always been the "normal" one of the crew by default compared to Dennis being a muderous arrogant psychopath, Mac being high key over religious and gay, Frank's grimeyness, and Dee being a bird. Plus as we learned about Charlie's childhood abuse and neglict the dumbing him down kinda makes sense to reference his poor upbringing yet he's still my favorite of the gangCharlie was a normal-ish guy back in Season 1 though. They dumbed him down a shyt load. First episode he won at dominos, whereas he couldn't spell the word now.
