I don't remember them having their own geek but I don't recall clearly so anders332 could be right. Maybe they rewrote the roles so that the person who was the geek became a regular agent? According to wikipedia she (Garcia) will be the technical analyst for the Criminal Minds spinoff. Imdb has details for three of the episodes shot, and she is in all three of them. I guess if she is based in Washington she can act for the new team just as easily as she can act for the main crew (whereas if they kept her going with the team as she did for a while, she wouldn't be able to fulfill that role)?
