I was so glad to see Alex back!! While I am a big fan of Law & Order: SVU, I tend to watch more of the reruns than the current season because I do not care for the character of Kim. I would love to see Alex stay or bring back Casey!! You can definitely feel the chemistry between Alex and the detectives. The story was also great. Watching Alex and seeing the transformation from wanting to put this kid into prison for murder and ending up making sure he got the medical help he needed was wonderful. This episode got me hooked all over again!
