Well, that was somewhat disappointing.
Having seen it all played out, I can only say that there was no reason NOT to include the entire team, at least the key CSI players, and not end up where they did. Four additional people in the inside would have pretty much assured that everything played out without issue. This was not, IMHO, one of the better scripts. For all the hype and buildup, it played out more like a quickly hacked together filler than a truly well thought out CSI episode.
Worse, to have the entire thing fall down because they guy who demanded it didn't do his part of the job is just classic. Does anyone else feel that this character is on about the same level as the Star Trek ensign wearing the wrong colored uniform? (expendible)
Now... having gotten the griping out of the way... let's move on to implications.
Sara made it clear in "revealing the situation" scene that she had no interest in dealing with Keppler. Any comment she had for Catherine would be passed in private. It is clear how she feels about Keppler, and at the same time suggests that she really doesn't think very highly of what was going on.
Warrick seems both insulted and live and let live.
Nick, well... Nick looked the most upset of the bunch. Certainly he lead the revolt, and he seems to have taken this situation very personally indeed. He didn't look pleased at all with Catherine assigning him "make work" (the bikes). He didn't look pleased at all in the end, and I suspect that something more is going to be made of this before the end of the season.
The only one who was a blank read to me was Greg, who just seemed to fade away as the episode went on.
From the look of the trailer for the next episode, it looks like they get down to some slightly more normal CSI stuff next time around.
Personal opinion: Keppler makes my skin crawl. All of the indications are that his character has a VERY questionable past, and that from a purely CSI standpoint, he is much more theoretical about things and less likely to follow just the evidence. I think he is certainly luring Catherine in with his "charm", and I have a feeling that this might be his downfall in the end.
