Grissom: I'm not going with you.
Catherine: What do you mean?
Grissom: I'm scheduled for surgery at Desert Palm.
Catherine: Surgery? (she walks over to him) Your hearing?
Grissom (nods): Yep.
Catherine: I'm sorry.
Grissom: I'm not. Has to be done.
Catherine: What can I do?
Grissom: Nothin', I'm fine. Take care of the case.
Catherine: Wha--ah, that's it?
Grissom: That's it. Um.... good luck.
