There was some great insight into Grissom\'s and Sara\'s minds. Sara has to learn that everyone lies and Griss\'s hearing further degenerates. You gotta feel for the both of them. Now, weather or not you feel bad for them or that these developments are good for them is up to you. For me, it is a little of both.
The humor also makes this one worth watching. Sex jokes = funny, no matter what age. It\'s always good to have a good giggle at bathroom humor. It is just a great, well rounded episode. I would not mind rewatching it.
