That’s a tough one! There’s many lists of “the most important” episodes of the X-Files, but it’s hard to find the right one. It depends if she wants to focus on the mythology, or on Mulder and Scully’s relationship, but you have to include to comical ones because they’re really good even though they don’t have mythology in it. There are also very good stand alones with no mythology and no important msr scenes…
I’m so useless here, I’m going to shut up, leave that here, and hope someone better than me can help you! 😀
