1 Work in St. Elsewhere
Summary: An investigation leads to a secret from Gibbs's past (crossover with "St. Elsewhere.")
Notes: For those of you who don't remember, Mark Harmon played Robert Caldwell (the first major TV character with AIDS) on "St. Elsewhere." "Family Affair" was also the title of his last episode (the Internet is a great thing, isn't it?) And that's all you need to know about that show to read this.
