• Well, not exactly romantic, but GSR related. Brass, Cathrine, Nick and Hodges all reach out to Grissom over the course of the episode.
• While talking to Brass Grissom says that he has spoken to Sara, and that she is in San Fransisco visiting her mother.(who we suspect is still in prison for killing Sara's father)
• While talking with Catherine, she tells him to go after her, and Grissom states that is not what she wants. When Catherine asks what he wants, he says that he wants her (Sara) to be happy.
• Nick implies they should talk about Sara by inviting Grissom out to breakfast with him.And with Hodges, Grissom admits that he was not ready to give up his job yet, but Sara was.
