Speaking of entrances, Laurence Fishburne was given quite the platform, appearing in shadow until the light clicked on and he was revealed. It'll be interesting to see if Petersen's last scene will replicate Frank Sinatra vanishing into distant spotlights, singing "Excuse me while I disappear." Considering the Vegas connection, I think that would be a perfect way for him to go.
But not just yet. First there's this very complicated, very gruesome case that's still unresolved. The Dick and Jane Killer, a guy who murders couples, seems to have a copy cat on the loose because the confessed serial killer, Haskell, is already behind bars. Brass and Grissom learned that Langston was using Haskell -- via remote feed -- as part of his classwork at the University. Without telling the prof, Grissom got into the lecture hall in order to question Haskell. It seemed like an oblique way to get Langston and Grissom to work together -- they eschewed the direct approach -- but it did immediately create a schism between Brass and Langston, something to be played out when Langston takes Grissom's place at CSI.
Because this was a two-parter, I was left on edge about creepy Haskell. But if a prisoner is in keep-away, as Gil points out, why was he allowed an unsupervised phone call to Langston to taunt him and tip the authorities off about the ninth D&J kill? Still, Irwin scared me as Haskell, so he definitely did his job well.
Interestingly, for me the best part of the show was how oblivious Grissom was to the way his abrupt news flash about leaving CSI is affecting the team. He seemed genuinely stunned by the tears in assistant M.E. David's eyes when Gil said he would miss him and not the work. Like the bugs and insects he studies, Gil is still in the cocoon emotionally.
For a student of behavior, he should know that some reactions -- like Hodges being hurt that he was not personally informed by Gil -- were predictable. The coolest (as in wise and aware, not reserved and uncaring) reaction was probably Catherine's. She anticipated it, perhaps based on the conversation at the end of the last show about Grissom upping the ante. My favorite exchange was Brass and Grissom's, suggesting that they'll stay in touch and perhaps go out on the boat and celebrate July 4th together. Gil's response, "You have a boat?" was priceless. It was so obvious they never socialized before and likely never would in the future. Their relationship -- and friendship -- was all about the office.
As for Fishburne's character, it's too soon to tell. He only met with Grissom and Brass and only on his own turf. He came off as authoritative and imposing, but also intelligent and observant. He also was pretty obvious when dealing with Haskell, like putting him on hold to conference Gil in on the phone conversation. That could have been done in a more stealth-like fashion. I suspect Part Two will have more opportunities for Nick, Catherine and the others to meet/clash with Langston.
