What is your dream pairing?
Probably Mulder and Scully.
Why? Well, for starters, I remember when I was younger I hoped to one day 'find my Mulder', haha.
That, and, like pretty much the rest of the world at that time, I shipped these two so hard. I just wanted them to get their happy ending :)
The only other pairing that would compare would be:
Sam and Jack, because like M/S, I always wanted these two to get their happy ending, and to get confirmation of their relationship. That, and the S/J fandom is the only ship/TV show fandom that I've ever physically participated in/contributed to, and still do to this day, so of course they have a special place in my heart ;)
