CSI creator William Petersen finally comes clean about what exactly is happening between the show's two principal characters, Gil Grissom (played by William Petersen) and Sara Sidle (played by Jorja Fox). However, if you are one of the millions who have tuned in every week since the show began airing, the fact that Grissom and Sara are engaged in a romantic relationship certainly does not come as a big surprise.

Following the current storyline of the show, the other major characters have absolutely no idea about Grissom and Sara, and Petersen intends on keeping it that way for the meantime, as not only does it intensify the obstacles the lovers must overcome, but also spares the other characters from being sidetracked from their lab work. Of course, the audience is fortunate enough to be spared from the shock, and clues pointing to the true status of the relationship have continued to surface throughout the course of the show.

The relationship is another classic example of forbidden love. Grissom is, as all the fans know, the head honcho of the night shift crew at the Las Vegas crime lab. Sara is a materials and element analyst who previously worked at the San Francisco crime lab. Professionally, they make a great couple, but romantically, it's a disaster waiting to happen, if only because of the boundaries they have crossed. Moreover, even if everyone else was to find out about them and gives them the thumbs up, Grissom and Sara would have to confront another social stigma. To state the obvious, there is a significant age difference between the two characters, and although they do seem to be on the same maturity level, one can only imagine the implications of the situation on their work and emotional well-being.

Petersen has certainly been able to heighten the complexity of the show by creating the budding romance, and has kept viewers glued to their television sets in sweet anticipation for the upcoming episodes of CSI.
