This episode seemed much more math-dominated than last week's season premiere and that is such a good thing. It makes me feel like I'm getting an education while I'm watching a fun TV show. This episode taught me some really neat stuff about car-remote technology. I never, ever thought about that before, but there is some really smart stuff going on with that little button you can use to find your car in big parking lots and open the doors when your hands are full. Leave it to Charlie to explain how that works so that even an English major can understand it. I did love that totally geeky date between Charlie and Amita, with their enthusiastic conversation about weird fractal vegetables and their jobs. Oh, and annoying new-guy Colby actually made me laugh this week. After threatening to shoot a terrified suspect in the back he said, "I'm not going to shoot you. I just didn't feel like chasing you today." Nice to know he has a sense of humor under that stuffy-cop exterior. I might actually even like him by the end of the season. Go figure. AC
