One of my favorite episodes ever. I absolutely loved the concept and the unique villain, and how everything was executed.
Not to mention the small parts, like McGee seeing up Kate's skirt and my wanting to glomp Gibbs at the end when he's saying "Don't you dare tell me that there is a reason for you to throw away what you had!", as we later find out why that's so important. I'm huggling Gibbs in my mind right now.
Plus, the girl who plays Sandy is such a cutie. Abigail Breslin? Is that her name?
