In the season-12 finale, "Homecoming", Nick announces to his colleagues that he is quitting his job at CSI, as he is no longer able to stand the widespread corruption in the department.

In "The End Game", Nick leaves Las Vegas when he is named the director of the San Diego PD crime lab. Nick reveals to Sara that he has gotten an offer that is too good to refuse, but it will mean walking away from the friendships he has cultivated in Las Vegas. Sara says that she will only be a car ride away and reminds him what Grissom would say to him: "You gotta go where you can do the most good".
