I missed the part with Brass, everything else I already know, but seeing it and reading it are two different things, I can't wait to see, plus I think that Brass's statement really shows how everyone likes Greg, and honestly, how could they not, he's the life of that lab and the csi's, he's like a breath of fresh air, smart and funny and honestly just like he said, a good guy that wouldn't hurt anyone who also may be a little insecure and at that same time totally empathetic.
But Wojo, I was THINKING the same thing as you, where's Catherine? The only thing I can think of is that she's working the other beatings that took place that night. And I too am wondering what her reaction is going to be..as well as the labs, if all the lab-rats really all rally around and make him the priority, as much as he's a csi now, he started in the labs and he's still like one of their own.
