CSI: Crime Scene Investigation

This episode is filled with references to the "Pilot." When Greg is showing around his replacement, her introduction is filled with references to Holly Gribbs. 1) Her name is Chandra, a reference to Chandra West, the actress who played Holly Gribbs. 2) Greg says it's the busiest lab in the country, while Brass said it was the #2 to Holly. 3) When she meets Warrick, she says she caught a lecture he gave about longitudinal toenail striations; Warrick's case in that episode was cracked by matching a toenail striation from inside the victim's shoe with the suspect. 4) When she meets Grissom, he asks Greg if he'd gotten her blood yet; she asks why, and he says, "So many reasons," the same line he gives Holly when he takes hers. In addition, Grissom's case in the pilot, and Warrick's case in this episode, a middle-aged man was killed in a bath tub, and the killer made it look like suicide. Also, Dr. Klausbach in pilot and Hodges in this episode each used the line, "She's cute," to describe the new girl. Catherine's case involves a stripper/hooker who drugs her client, while Nick's case in the pilot was a hooker who also drugged her client, both of whom end up dead. Finally, both characters lasted only one episode!

Greg: Duct tape. So the shooter stuck the gun in the toilet earlier to avoid the metal detector. Grissom: Echoes of Michael Corleone. This is an allusion to the 1972 classic The Godfather where Michael Corleone also stuck the gun in the toilet.

When Nick and Sara catch up with French Stewart in his Elvis garb and he recognizes them, Sara holds her hands up with the first/second and third/fourth fingers splayed into a V - a reference to the Vulcan greeting Mr. Spock used in the 1960s sci-fi show Star Trek.

Grissom: "Bring me the head of John the Baptist" A reference to the beheading of John the Baptist in the Bible, found in the Gospel of Matthew, Chapter 14, Verse 8.
