NCIS, Season 10

[At NCIS headquarters, Gibbs interrogates McGee's father, Admiral John McGee]

Admiral McGee:
[points at the one-way window] Who's behind the glass? Who's watching?

Gibbs:
You scared he's gonna see you break?

Admiral McGee:
My relationship with my son is none of your damn business.

Gibbs:
You make him think he's nothing. You're the one with nothing.

Admiral McGee:
[glaring] You will respect this uniform.

Gibbs:
Answer the question!

Admiral McGee:
This uniform provided for him, for his mother, for this whole family!

Gibbs:
Why lie? Why avoid the truth? Why avoid your son?

Admiral McGee:
[resignedly] Alright. [he sits down] Because I'm sick. No one could know. Stage 4. I wasn't feeling well when we showed up for the exercises. I knew Haber was top notch, so I transferred to the Borealis. Haber gave me something for the pain... but he knew what was causing it.

Gibbs:
He was gonna report it to NAVCENT.

Admiral McGee:
Doctor-patient privilege is a little different when it comes to national security. So that meant the end of my career.

Gibbs:
It's motive to keep the commander quiet.

Admiral McGee:
Gibbs... I've been a lot of things. I've been a lousy father, I've been a son of a bitch. But I'm no murderer.

[Watching on the other side of the glass, McGee is visibly upset, tears running down his face]
