NCIS, Season 9

Gibbs:
Go home, McGee. You can't be professional. Go home.

McGee:
Boss, I won't let you treat her like that, she's my grandmother.

Gibbs:
She's also the lead witness in a murder investigation. What do you want me to do? Needlepoint my questions?

McGee:
Penny had nothing to do with Lieutenant Booth's death.

Gibbs:
I never said that!

McGee:
What are you going to do? Break her down until she cracks?

Gibbs:
Until I am done, Tim! I don't like this any more than you do, I know she's a family member.

McGee:
Boss, she means everything to me.

Gibbs:
I respect that. This is about murder, a guy is dead. Enough! We find what was in those papers. We find Booth's killer.

McGee:
And she's the one that can tell us. She will talk to me.
