It's one of the best and touching episodes with so many examples of humanity and caring shown between SVU family and also toward the victims. This episode is one of the most memorable ones that I would watch over and over and it would still bring tears to my eyes.
P.S. Rollin's hint toward Benson when Langan entered the squadroom was very interesting. I am happy that Mariska Hargitay and Peter Hermann are actual couples. They are good fit.
