What up with John Doggett on the X-files?

John Doggett, portrayed by Robert Patrick, is introduced in the later seasons of "The X-Files," specifically Season 8, as a new FBI agent who partners with Monica Reyes and initially works alongside Mulder and Scully. His character is a skeptic and a former police officer, which contrasts with the show’s usual focus on the supernatural. Doggett's role was to bring a more grounded perspective to the series, especially after David Duchovny's Mulder took a reduced role. He becomes a key figure in the ongoing mythology and helps to explore themes of belief and skepticism within the paranormal context of the show.
