Mmm.. I'll give it to ya AshleyWillows. What I was looking for was Grissom is concerned for Sara. In Commited, he saw her with a knife to her neck and was scared for her. Nesting Dolls, he went to her apartment and talked with her. Butterflied, he became obsessed with the crime scene.
All episodes consisted of people in conventions. Fur and Loathing = Fur/Animal get-together. Big Middle = "Big" people get-together. Who Shot Sherlock? = People who re-inacted the past (so to speak.)
