The man can cry!
In the short time I've been watching CSI I've seen Nick tear-up quite a few times. He does it so well, tearing-up without actually crying. I just watched the episode where the hockey player is killed. At the end Warrick, who has found out he can not continue his new relationship with the jazz singer who is a junky, goes to gamble, succumbing to his own addiction. Nicks shows up and sits beside him to play. Warrick asks what he's doing there, and Nick says, "I'm playing cards (pause) with my friend." Nick nods to the dealer, and his chin looks like he's going to cry. But, I want to say it looks like George is going to cry because that line really did not necessarily call for that emotion, but it just seemed like he actually felt it, kwim?
For what it's worth, I usually think posts like this are so silly!
