This episode is my, hands-down, favorite Miami episode ever! The opening scene was brilleant, we were just as confused and scared as poor Jason was.
And as for Jason, he wasn't your typical guilty yet innocent guy. He had real depth to him, he was a former drug addict that was trying to get clean, he grieves for his father after telling him to drop dead then finding out he did a week later. Jason just added to the episode for me greatly.
Another character whos depth and past was brought to light was Natalia. I feared that this episode would be deminishing to her character but in reality, it was the oposite. Though we have heard the Nick story before, "Sleepless" brought a new edge to Natalia's hidden past. He used a dream defence to get out of alot of charges, meaning the abuse must have been much worse than we've speculated.
Even more depth was giving to Horatio, who has been noticably cold and distant in last and this season. He and Ryan vow to keep the truth of Nat's ordeal a secret (even to Nat) in order to protect her. The team-scene was also great as was the hospital scene. It was nice to see the teams bond be brought to light.
My only problem was that I feel the episode was rushed. Nat's hallucination lasted only minutes. Even before that, when Ryan and H realised she was in trouble, they automatically knew how and where to find her. I was expecting after Ryan says "She could be anywhere" to jump to Nat's POV, probably speeding through traffic or running for her life, more "Nicks" popping up and flashbacks.
And even after finding her, the next scene was the hospital scene. I think something else should have happened there, like the house scene then that. At least give some sign that Nat spent some time in the hospital before waking up. It seemed that her scenes were squashed together, then another while before she showed up.
Though I have a few quaries with this episode, I can't fault it. Between the brilleant camrea shots and Special effects, to the depth and plots, this episode was one for the history books. I feel bad for the next episode, nothing can top "Sleepless" in my mind and surely many more.
