In the first three episodes of this season, Rey Curtis has returned to his old NYC precinct and is partnered with SVU detective Olivia Benson. While working a case involving a murdered maid, details pertaining to an old case Curtis worked in the late 90's emerge. From there, the second episode was a flashback to a case Curtis worked with Lennie Briscoe, while the third came back to the present and had Mike Logan help Curtis and Benson in a case. In all three of these episodes, details about the "Preppie Joggers Case" are revealed and these new episodes are no different.
What does change starting with Episode 4 is the amount of guidance the game gives the players. Basically, the training wheels are off, you are no longer guided and directed in which questions you should ask, and you don't get the guidance as to when you should use which objections. Now you really start applying what you've learned in the first part of this season.
