Billy’s brief cameo at the end of THE TWO MRS GRISSOMS certainly got a lot of CSI fans excited. The writer of the episode, Christopher Barbour shared his thoughts on Billy’s return and much more in his recent interview with Shane Saunders.
Saunders: Some pretty major events happened in your last episode “The Two Mrs. Grissoms.” With the show eleven seasons into its run, what made the writers decide to do an episode with a heavy focus on Grissom (William Petersen), even though he is no longer a series-regular?
Barbour: (laughs) Yes, indeed. We love Jorja Foxand Sara. And obviously, Sara being married to Grissom, there was a need to address how that relationship works in some way, shape, or form. We are a procedural show so it’s more difficult to sort of delve deeply into the lives of the characters. You usually get suggestions and snippets of that. In the beginning, the episode was more focused on Sara and her relationships. I was actually surprised that we were able to get Billy to come back and do the cameo; I was thrilled.
