Season 9, Episode 11: The Grave Shift

On a lighter note, Ecklie offers Grissom's office to Catherine. Catherine doesn't want to take it herself, but the new Undersheriff tells her that they can't afford to leave the office as a "shrine" to Grissom. It's nice to see Ecklie hasn't changed too much--he still does love micromanaging!

Catherine decides to give the office to Nick, who in turn decides to share it with Greg and Riley. It's a nice solution to the problem of who should inherit Grissom's old digs.
