Deep Throat

I always loved the dynamic of Mulder and Deep Throat. Something about the two of them together always felt so right. While the pilot episode does a lot to help us understand our two main characters, this episode really dives into the worldbuilding and lore of the show (and what's to come). While I doubt there are people out there who would dare watch this show out of order, I must insist that, if you are one of these people, you MUST watch this episode. This is one of the most important episodes in the series, and undoubtedly the most important episode of the first season.
