Looking for a special episode...

Hello everybody !

I am a new member of this website, and I really love the X-Files !!!
Currently, I'm looking for an episode that I saw a long time ago, and I think that I only saw the beginning of this episode, lol !
Here is the scene : a man arrives in front of the house of a friend of him, and he sees the daughter of his friend sitting in front of the house. He asks her where is his father, noticing that the little girl looks sad and disturbed. She tells him that his father is in the garden. Then the guy goes to the garden to find his friend sitting on a swing's sit, but doesn't see his face, because he has his back to him. He approaches the guy and asks him laughing what he's doing here. Then he realizes that his friend is dead, his eyes are glassy.
If someone knows which episode it is, please tell me, I'm looking forward to see it again !!!!!!!!!
