You two came along and you taught me not to hide from it but to have the guts to shine a light directly into the darkest corners and if given the choice between advancing my career by being blindly loyal to some faceless puppeteers pulling strings from the shadows or to throw in with you two? Make no mistake about it, I'd make the same decision every single damn time.

Mulder: Do you mind if I ask how she died?
Davey: Yes.

Imagine a government who could literally control the minds of its citizens by exposing their minds to a poison. It's happening. It's happenin' right now!

Davey

Maybe he's out meeting with an interior decorator.

Mulder

Scully [reading note]: The monsters are here.
Mulder: The monsters are here.
Scully: Does that get your juices flowing?
Mulder: As much as I appreciate any reference to my juices, my only concern here is Skinner.

Father says there's two refuges in life for sorrow, music and cats, but I think cats are creepy.

Davey

It appears he may suffer from moderate to severe constipation.

Mulder

Keep crackin' wise. You got no idea my state of mind.

Mulder

We have no proof that the body is William, Scully.

Mulder

I don't know if you are who I think you might be, but if you are, this is what I'd say. I'm sorry, I'm so sorry that I didn't get a chance to know you or you get a chance to know me or your father. I gave you up for adoption not because I didn't want you or because you were any less loved. I was trying to keep you safe. I hope you know that. And maybe, maybe I should have had the courage to stand by you, but I thought I was being strong because it was the hardest thing I had ever done. To let go and know that I was going to miss your whole life but it turns out that this is the hardest thing, to see the outcome and how I failed you. I need you to know that I never forgot you and I thought, I felt, even recently that we were going to somehow be reunited. I wish I could have been there to ease your pain. Oh my god. This is so inadequate. I'm just so sorry. I'm so sorry. [sobs]

Scully

Barista: Bob! Double shot cappuccino extra foam.
Scully: Bob?
Mulder: Like I want to explain "Fox" for the millionth time.

Why would he call you here just to see him die?
