(Explaining how he knew where to find Scully) I checked where we always stay in Philadelphia. I was sure you wouldn't abandon me.
S4 E13Never Again
(Making fun of Scully's new tattoo) I was thinking of having an NY tattooed on my ass to commemorate the Yankees' World Series victory.
(To Scully) Congrats on making a personal appearance in the X-Files for the second time!
S4 E14Memento Mori
[writing in her journal, to Mulder]
For the first time, I feel time like a heart beat, the seconds pumping in my breast like a reckoning. The numinous mysteries that once seemed so distant and unreal threatening clarity in the presence of a truth entertained not in youth, but only in its passage. I feel these words as if their meaning were weight being lifted from me, knowing that you will read them and share my burden as I have come to trust no other. That you should know my heart, look into it, finding there the memory and experience that belong to you–that are you–is a comfort to me now as I feel the tethers loose and the prospects darken for the continuance of a journey that began not so long ago, and which began again with a faith shaken and strengthened by your convictions. If not for which I might never have been so strong now as I cross to face you and look at you, incomplete, hoping that you will forgive me for not making the rest of the journey with you.
I refuse to believe that.
For all the times that I've said that to you, I am as certain about this as you have ever been.
(About Mulder's tiny office) At least he doesn't take an elevator up to get to work.
(Snarky smile) You think I'm the devil?
You can't ask the truth of a man who trades in lies.
The truth will save you, Scully. I think it'll save both of us.
You wish to bargain for Agent Scully's life?
(shouting) WHAT WILL IT TAKE?!
(on the phone with Mulder) There's always another way. [Hangs up; camera pans around to reveal Cigarette Smoking Man]
Yes, I think there is. If you're willing to pay the price.
S4 E17Tempus Fugit
(sarcastically) I didn't know it was your birthday, Scully.
Mulder, ... you have never remembered my birthday in the four years I've known you.
That's the way I like to celebrate them ... It's every four years, it's like dog years that way.
Dog years? Thank you.
I am hesitant to speculate.
(rolls eyes)
MMMike Millar
(to Mulder, sarcastically) And if any of the capable men and women find... Doctor Spock's phaser or some green alien goo, we'll be sure to give you all the credit.
(to Mulder, sarcastically) You sure know how to make a girl feel special on her birthday.
Nine minutes, Scully. Do you remember the last time you were missing nine minutes?
