Horatio finally gets some closure on his brother's, Raymond's, murder when Susie call him for help. Horatio finds out that Raymond fathered a child with Susie, and with Susie's help, he finally got the evidence needed to put the bad guy away. Along the way, Horatio had to come to grips with Raymond's drug use while undercover, and what price he paid for it. This was the better part of the episode. The other case with the live feed "sorority girls" was tangentially interesting, but pretty tame.
