CSI: Crime Scene Investigation2000

Catherine Willows:
You were with her all night, can you explain why? I know you don't go home and cuddle your insects every single night, but why would you go there knowing we're in the middle of an investigation? And now she's a prime suspect with you as her alibi.

Gil Grissom:
It was a social call. That's all.

Catherine Willows:
So, when your personal life gets tangled up in a case, that's off limits?

Yes.

Catherine Willows:
Isn't that a little hypocritical?

Gil Grissom:
Apparently so.

Catherine Willows:
You know, I'd slap you but I think you'd enjoy it too much.
