Among the 13 characters who made up the main cast of “CSI: Miami” during its run, only Horatio Caine (David Caruso) and Calleigh Duquesne (Emily Procter) appeared in every single episode of the series (per IMDb).
Since we see much of the show’s world through Horatio’s eyes, it’s not surprising that he pops up in every single episode of “CSI: Miami.” Throughout the show, Horatio generally remains the same dedicated man we meet in the pilot, determined to protect all potential victims at any personal cost to his own body. Along the way, he develops a strong bond with his team and becomes less and less ethical in his approach to cases.
Horatio’s blunt, no-nonsense style becomes his hallmark, and he never fails to side with abused or molested children and women, a fact that echoes back to his own tragic past. By the time “CSI: Miami”‘s series finale has rolled around, Horatio has loved and lost — a Season 4 marriage to Delko’s sister, Marisol (Alana de la Garza), ended with Marisol’s tragic murder — but gained himself a family in his colleagues.
