Honestly though, I'm not sure they need to add anyone new for supporting roles (other than Morgan/Elisabeth) when they have many recurring characters that they could make more prominent on the show such as Archie, Henry, Mandy, etc. I think that would probably be better than us having to get used to a new character.
They've always had at least five CSI characters though - with Ray and Catherine leaving, that just leaves Nick, Greg, Sara (part time still?), and Morgan - so they'd need another CSI, especially if they go back to two-case episodes (which I really, really hope they will). If they'd kept Wendy, that would've worked perfectly. :shifty:
I agree that the lab rats could use more time too - in the earlier seasons, Greg was a regular character, in almost every episode, as a lab rat. I guess Hodges is taking over that role now, although he tends to be out in the field more than Greg used to (which is odd, since he supposedly hates the field). It seems like they're moving away from the lab in general though, making it more about the 'cop' stuff than the 'science' stuff.
