Jimmy Smits joining Dexter for season three.

Jimmy Smits (L.A. Law, The West Wing, NYPD Blue) will be joining the cast of Dexter for the third season.

Smits will be playing Assisant district attorney Miguel Prado. Prado is described as “ambitious” and “charismatic” and comes from a well-connected Miami family.
The thing that really caught my eye was that, according to The Hollywood Reporter, Dexter will “join forces with Prado, who has risen in the ranks because his aggressive stance against crime, in the pursuit of a murderer who affects both of their lives directly.”

Dexter is not a police officer, but simply a blood splatter expert. Does this mean that Dexter’s dark side is known to Smits?
Smit’s contract calls for him to appear in ten of the twelve episodes that will make up season three.
Seasons one and two of Dexter have been very strong, I can’t wait for season three
