Happy ending: After solving his final case with CSI, Gil Grissom packed up his office and took his last walk down the hall. He noticed all his co-workers on the way out (even spending a moment with the program from Warrick's memorial service) and exchanged a final smile with Catherine, who seemed to give her approval for him to exit. The GPS marking Costa Rica meant only one thing: Grissom was planning to spend his days with his two great loves: bugs and Sara Sidle. In a meeting reminiscent of Carol Hathaway reuniting with Doug Ross when she left “ER,” Grissom found Sara in the jungle and the two shared a long kiss. Even longtime GSR doubters had to give these two their happy ending at last.
Viewers share their two cents: Writers Carol Mendelsohn and Naren Shankar gave viewers a chance to say their final piece to Grissom using Hodges, who told Gil, “As your friend and colleague, I feel it is my obligation to tell you what a colossal mistake you are making.” Speaking for many worried viewers, he added, “You take yourself out of the equation and who knows what’s going to happen.” And when Hodges proclaimed, “The bad guys will win more often if we don’t have you,” it was hard not to think that he was referring to “CSI’s” main competitor, “Grey’s Anatomy.”
Grissom told him, “It’s the right time for me to go.” And that, it seemed, was William Petersen speaking to all his loyal fans.
The case: When last we left off, Grissom and Professor Ray Langston had just found what seemed to be the Dick and Jane Killer’s 10th victim, Jeffrey Masters —except for the fact that DJK was in prison. But they still needed to find Masters' wife, Maureen. Grissom thought that DJK's accomplice must have been someone that the killer was communicating with in Langston’s class.
The CSIs conducted an experiment to see if they could line up DJK’s eye line to one of the students (do colleges really have assigned seating?) to determine who he was trying to communicate with.
This led them to Tom Doniphon. When they searched his house, Greg found shoes that matched prints found at Gerald Tolliver’s murder scene. And Nick found a VHS tape that documented DJK’s first murder (and showed Tolliver and Doniphon in the background when DJK picked up the victims). It also showed that DJK took the women to a house to kill them, and the CSIs determined the house was on Lake Mead.
Fool him once…: Langston, hoping to find Maureen alive, decided to go talk to DJK in prison. “I’m here to gloat,” he told the killer, insisting that they’d found Doniphon, Maureen and the kill house. “If you don’t tell me what I want to know,” Langston threatened DJK, “the only person who will ever hear the sound of your voice is you.”
But DJK wasn’t fooled; he quickly realized that Langston had nothing. “I’m a teacher, too,” he taunted Langston, “and my students are everywhere.”
Moonlight matters: The CSIs needed to find the kill house, and Grissom suggested using the position of the moon on the time-stamped videotape. Nick called the technique “forensic astronomy.” And it worked, leading to the house where sharpshooters brought down Doniphon before he could kill Maureen. Grissom also managed to find all the other women’s skeletons underneath the floor boards.
Job offer: Langston was only a “special consultant” for the DJK case, but Grissom suggested he take an entry-level job with the team. “We’re not cops,” he assured Langston, adding, “The hours are terrible, they money’s bad…” But Langston looked intrigued.
One more great moment: While they were working on the case, Hodges told Langston, “We usually don’t need a consultant. When the team gets a case like this we go into hyperdrive. It’s why we get up in the morning. I can’t imagine my life without it.” Grissom’s raised eyebrows at this little speech was his classic “what’s with the drama” response. Like Hodges, we’re going to have a hard time letting Grissom go.
