All in all good episode. I thought it was a little too predictable though. Some things I didn't like; the girl had boots on and somehow her toe nail not only got in but stayed in the guys mouth. The whole Greg beat down thing was confusing. First off, you would think they would scatter right away when they see flashing lights, than for the kid to run at the police car with a brick, it could be anyone in that car. I'm also trying to figure out why all the CSI's carry a gun except Greg. I would have liked to seen him fight back a little bit, especially knowing all the kids were under 18. Quick thinking to run him over with the car. The kids brother will turn up again down the line, they just don't do those types of things without future storylines. I also thought it was weird that Sara walked up and Greg was just laying there, no medical attention, and it looked light as day out. 5 or 6 hours had to have gone by and he was just laying there, let alone he called for help before he went down the alley and the transponder said help would be there in 5 minutes. OK what am I doing, i feel like I'm criticizing the show now and I thought it was the best one yet this season. Good to see Stokes & Warrick sticking up for their boy. Next week looks interesting yet weird, hopefully its good.
