I think this is one of the best SVU episodes that have ever been made. The suspense is awesome. Props to Det. Benson for sticking with the girl. Like one of the other people that commented, Mariska should have received an award for this EXCELLENT job. Her enthusiasm was amazing as was her determination. I always enjoy watching SVU because of the detail with which the episodes are carefully crafted. This episode was unlike others in that it wasn't the typical rape-homicide. There actually was a living person they had to track down in time. I also loved how they tied in the sound loop and the tower virus. If you get a chance to watch this episode, don't miss it!
