Hodges (as Grissom is cleaning out his office): Okay. So this is really real. Fine. So, as your friend and colleague I feel that it is my obligation to inform you what a collosal mistake you're making.
Grissom: Hodges...
Hodges: Guys like us just don't get to hang it up. This job is who we are. We are the thin blue line between order and chaos. You take yourself out of the equation, who knows what's gonna happen. That's the Butterfly Effect. You taught me that. The bad guys will win more if we don't have you. Who is Watson without Sherlock Holmes?
Grissom: Watson was a genious in his own right. ... It's the right time for me to go.
Hodges: Okay. (walks out)
