They said 'elements' of the song would be used throughout, which I took to mean that some of the meanings of the lyrics would be used in the script. They did say it would be played at the beginning and end. I finally got around to watching this episode today. I was nervous about it, so I put it off til after I read some posts. Wow, everyone has some type of reaction, many with different takes on it. So I figured I just had to see for myself. I have to say I was pleasantly surprised. I thought it was incredibly well done, with the video of Sara mixed in to show us what Grissom was thinking about, and the acting was exceptional. I could really see Grissom's pain. Jorja was great in the video, acting happy, but obviously with some sadness in her voice. And I thought LH did a great job of trying to get Grissom to see his inner self and relationship issues. I thought she was provocative, but without going overboard and being sexual. The chemistry was there with WP, but there was no sexual tension like they have had in the past. I really think they are just good friends. I have to say I really like Catherine in this. She feels for Grissom, but she is clearly taking the reins of the investigation and running the case; leaving Grissom to work out his problems. Loved the 'change the channel' comment, and her scene with Hodges. That was the perfect amount of Hodges for me. I was kind of bummed that the case wasn't solved, but maybe it will be revisited later. I'm pretty sure the 'new LH' will be back, was her name Michelle? It wasn't lost on me that she was coming on to Nick. CSI, the next generation. Riley is clearly the new Sara. Which I'm sad about, but reality bites. Greg needs someone to talk with like he and Sara use to do. Overall, a very good and a very emotional episode. Love Linkin Park!
