The X-Files, Season 6

[Cigarette Smoking Man sits in the X-Files office looking at picture of himself and Bill Mulder; Spender enters.]

Spender:
Get out of here.

Cigarette Smoking Man:
This picture you have - I haven't seen it since you were born. You probably don't even know who the other man is.

Spender:
I don't care. Get out.

Cigarette Smoking Man:
It's Bill Mulder, Fox Mulder's father. Isn't that something. He was a good man... a friend of mine... who betrayed me in the end.

Spender:
I know more than enough about your past... enough to hate you.

Cigarette Smoking Man:
Your mother was right. I came here hoping otherwise. (takes out gun) Hoping that my son... might live to honor me... ...like Bill Mulder's son. (takes out his gun and fires, then leaves the office)
