The episode was okay. i finally had a chance to form my own theories, and that's what i like to do the most when i watch a crime show. the only thing that bothered me was actually Keppler. i find him OTT, he just tries too hard to be a unique personality and IMO it doesn't work and looks unreal. he annoyes me greatly. instead of giving some screen time to the old cast which they, due to Grissom's hiatus, should have more, the episode focused on this new guy. i think they tried to hard to categorize him, and show how "cool" he is. that was one thing i didn't like. i truly hope Keppler won't be in further episodes after Grissom's return.
