There is not really character development in this episode, except for the relation Ling-Richard which gets more and more spicy. The cases are not particularly interesting and the the birthday crisis is not even a new story line for the show, however it is worth seeing just for the final scene guest starring Barry White! It's one of the most special moments of the show: John Cage meeting in person his "Alter ego" and all of them dancing to "My first, my last, my everything". It is a very moving scene for anyone who has seen all the previous episodes.
