It's sad to see Marg H leave CSI. She's been giving us great entertainment every week for 12 years. Tonight's episode is touching. I think when she was making the speech at the end of the show, she was really saying her lines from her heart. I felt very sad that she is leaving but I read in one of the interviews with the Executive Producers that the door is always open for Marg to come back. I hope she'll show up once in a while in the future CSI episodes.
I like the twist of tonight's story. Very imaginative of the writers. Nice!
