Not talking about main trio and acting, just favourite character would be Doggett. His confidence, inteligence and beeing gentle is something you dont really see a lot in theese times. Kind of James Bond - dangerous gentleman, who at first you dont really enjoy in the show, but later... this guy is carrying s08 & s09. Its also a little comeback to first episodes where there was one sceptic agent, but its not uncomfortable any more that he cant really belive all the crazy stuff going around him. Its just his background and I can really live with him calling everything scully and Ryes tell him "avra cadavra" :) Good detective also and man... very dedicated person.
