Oh dear, here we go again. You'd think TPTB would be getting tired of putting our CSIs in danger like this. We've already seen: Nick get blown up, Sara get buried under a car, Catherine's daughter get kidnapped, Catherine get raped, Nick get pushed out a window, Brass get shot, Brass get suspected of murder, Warrick get suspected of murder, Greg get beat up, Greg get blown up...isn't that list long enough for them? As much as I enjoy the drama (if there were no character storylines at all I wouldn't still be watching), but really, it's a little much if you ask me.
That's interesting about Billy. I'm honestly not sure if he wants to come back for another season, despite what he said in that interview with Anthony LaPaglia during the crossover last year. The show has been going for a long time, and he keeps taking these breaks to do plays; it makes me think that he wants to give a last hurrah to CSI.
