The investigation is further complicated when it is revealed that Hawkes once knew the girl. Further up town, a rich playboy is found drowned in his indoor lap pool with his former maid as a suspect.

Peyton is seen for the second time this season and she has been only mentioned once for 5 episodes. Apparently Claire Forlani has only signed for 4 episodes and according to Anthony E. Zuiker it took a lot of convincing for Gary Sinise to agree to Mac having a romantic relationship, which brings up the question if their storyline would build up to anything. Mac uses Hawkes to set an example to the whole lab. He doesn't even let Lindsay leave as he goes overboard on him. That makes for a very unsettling and discomforting scene. It is kind of weird how after discussing about potentially divisive issues, Mac and Peyton are so quick to brush them off in their vending machine date. Mac condemns Hawkes' emotional involvement with the case and he accuses his boss in turn since Mac's emotional judgement is allowed to stand. It is interesting that despite being lucky and McQuinn being proved guilty, Hawkes is right. Lindsay takes the 7 train home. We knew in the previous season that she wanted to move to Manhattan, but apparently she gave up on the idea and settled for Queens. Flack calls Danny Danno for the first time. Despite the effort to hide it, Anna Belknap's pregnancy is very obvious when she first walks into the train with Hawkes. Mac wears a tie for the first time since the end of season 1 when he dresses up for the opera. Danny's necklace is a different one: instead of his silver chain with the dogtags and the charms, he wears a black cord with a fashion piece attached. In Murder Sings the Blues, it's Mac Taylor's birthday. Peyton and Sheldon worked together for 4 years before she left to teach at the Columbia University. See more
