Although it pained me a little to see Nick and Greg fighting, I think it was perfectly fine the way they did it. Greg is frustrated, and obviously Nick is not because he's second in command and doesn't know how it feels to be Greg. So Nick would side with Catherine of course.
I'm glad Greg got plenty of screen time in this episode, but the part with the new job wasn't in this one, was it? Unless I just missed it...
I'm so mad about Hodges, though. Are we supposed to believe that after all the press leaks with Grissom, Hodges has never been told that they're not supposed to talk to anyone from the press JUST BECAUSE Catherine didn't specifically tell him not to? Bull. Everyone knows department policy by now, especially kissass Hodges. And of course he wasn't punished at all.
