See, once again I love the way the wrote his character Dr. Raymond Langston in and on the show. He's got a medical background, and is brilliant, in his field and Grissom offered him this position because of his extensive background. The way he blends and bonds with the team is incredible. especially Nick [rock star of CSI] and Sara. She has always loved working with the boys of CSI, over the girls, she's got a excellent rapport with all of them, and not so much with the gals on ths show as her character Sara, that's just a fact. But she's really got a great chemistry with Ray. They all admire him and he's brought real class, style and elegance to the team Their more relaxed and calm with his presence. He's one of the best characters that CSI has ever had on this show. Thank's writers:bolian:
