I think I need to get meta about this. I started watching this show when I was thirteen, and I was so in love with Mulder. I thought he was the absolute be-all end-all. The living end. I loved Scully, too, but there was no doubt that Mulder was my favorite. I went around spewing about how I wanted to believe, reading books on UFOs and abductions. I was pretty deep into this whole thing.
So I never wanted to see Mulder’s faults. Like the fact that he’s a social nightmare and people generally don’t want to be around him for a reason. That he does seem crazy. To a kid who wanted to believe, he seemed like a martyr, but in retrospect I can see how Scully endured so much. How the people around him weren’t assholes but rather reasonable people who didn’t expect an official with a badge to try and make everything, literally everything, about aliens.
Therefore I love this idea, that Scully validates him by being a skeptical, reasonable person who still loves him despite their differences. But I clearly remember watching this at a younger age and thinking that Mulder deserved to be accepted regardless of who validated him or didn’t. It’s amazing what maturity can do to your opinions.
And as a total, random aside, I mentally applied this to Sherlock so easily. John is Sherlock’s human credential. If John can put up with Sherlock, then the others around them start to assume there must be something worthwhile there.
