Here's why Fox Mulder and Rupert Giles would get along.
Since watching Twin Peaks and falling head over heels with both Denise Bryson and Fox Mulder, it made me think about how characters from my other fandoms would interact with him. And the first thing that came to mind was Giles. In this scenario all of the mysterious deaths in Sunnydale finally make it to the FBI (not the stupid initiative) and Fox Mulder and Dana Scully arrive. Most reports come from say, high school students that go to the Bronze, so naturally they go to Sunnydale High. Scully being ever so logical starts interrogating, asking people questions- and Mulder makes his way to the library. There, Giles is researching in his big book of demons which peaks Mulders interest. A few hours later Scully goes to look for Mulder, and the Scooby gang goes to find Giles. They all find the pair sitting in chairs, kicking their legs, fangirling over things the other has figured out in the world of the unknown. You're welcome.
