S6 E19 has got to be one of my favorites
I'm watching through X-files right now for the first time and I am enjoying it more than I thought I would honestly. I basically marathoned the first 5 seasons after the pilot episode got me hooked.
I just finished Season 6 Episode 19 and man...I did cry at the end when it pans out to the sky with the Grays singing in the background. (If you've watched it yet, you already know why.) The entire episode was so enjoyable to watch. I was giggling at times (especially when **small spoiler** Mulder takes a bite of Scully's ice cream. Her smile and playfulness was so awesome!) and I loved the banter between the Grays.
I am not a baseball fan (don't hate me, I don't have anything against it, it's just personally not my taste), so I almost skipped the episode and I'm sooo glad I didn't!
Anyways, I loved it enough to make a random Reddit post at 3:30 AM. Go watch it, or rewatch it. I recommend.
