Renee Walcott is a hard-nosed District Attorney for Boston, Massachusetts. She’s stubborn, hard headed, forceful, and out for justice. She’s been known to occasionally bend a rule or leave out facts to make her cases stronger, yet she gets furious (not an understatement) when the coroner’s crew doesn’t follow her instructions, or offers their further assistance on cases—when she doesn’t want help. She and Jordan don’t get along (though they are very similar when it comes to getting justice—they both actively seek it).
Season Two
In the episode "Prisoner Exchange", Renee Walcott, invades Garret Macy's office. She wants to talk about one of his cases, Mr. Fisher, whose autopsy he has not finished. They exchange some heated words and she promises that if he doesn't stop getting in her way, he will be "wounded." We find out on her first big murder case in Boston, she had a case of a 6 year old girl murdered. Despite getting inconclusive DNA testing results, she had the suspect put in jail for his past history. While on trial. Garret informed the court that the results were inconclusive and therefore the results were overturned and the suspect was released from jail. Renee joins with Garret to try to get the suspect back in jail where he belongs. Renee shares a personal story with Garret about how she had an ex named Eddie. They could not have children despite trying so he broke it off. Later on she confides in Garret that she did indeed bury the DNA test because of her father saying female lawyers were not feminine so she always felt she had to work harder to prove she was worthy. Together, Garret and Lily find a body of a little boy killed seven years ago at the suspect's house then save another girl who was being taken at that same time. At the end of the episode, Garret is joined by Renee for a drink. She admits she owes him one. He said he might collect sometime.
In the episode, "John Doe", Renee shows up to discuss the cop killing case with Garret. She thinks the cop dies by suicide. Garret disagrees. She practically tells him to rule it was a suicide. Dr. Wolcott comes to talk to Garret to discuss the case. She wants him to call the case a drunk cop that took his life. Garret said that his first obligation is to the victim. He said with two shots and no gun, it has to be ruled a homicide. She said he was making a mistake. He did not feel that way.
In the episode, "Cruel and Unusual" Garret and Renee discuss a case as well as the death penalty. Garret is against it, Renee is not. Garret said it doesn't detour others from doing the crimes. Renee told Garret because he goes above and beyond, isn't biased and does a good job with a spotless reputation, he has been chosen to do an autopsy on the man recently killed by lethal injection. So Garret is going to go to North Carolina with Renee. Garret told the D.A. that he was not on any team so was going to do the autopsy the right way. On the way to the autopsy, Garret got stopped in the hall by the victim/murderer's parents. Despite Renee's thoughts, Garret listened to the parents who said the victim was guilty and deserved to die. The parents insisted someone butchered their son. Garret assures them that his autopsy will be through and objective. Renee comes to visit Garret's hotel room and asks him if he would like a bite of food. He thought she was there to ask about what the parents said to him. Garret and Renee went to the prison to see the tape of what happened to the deceased. The process is described to him as the prisoner gets his last meal, then is strapped to a table. He has IVs started and is given something to help him sleep, then to cause a heart attack and then the last one to stop his heart. This didn't happen here though. Instead they couldn't find a vein so used his neck and then he struggled and suffered. Renee once again visited Garret. She was upset and neither were hungry. Garret offered to have her stay with him if she didn't want to be alone. She said she was not upset having honed her feelings since the age of 6. She wanted a drink so he offered her one. Garret and Renee both said they didn't like each other and she said just kiss me. Renee comes to see Garret in the autopsy room. Garret said that last night was a real comfort and Renee said they call it sex. Dr. Martin came into the room to assist Garret. They noticed that he had no sedation drug in him. Garret found out he had hives and was allergic to something. Garret figured out that someone wasn't trying to poison him but instead trying to save him. Garret asked the victim's mom if she went to see him. She said she brought a cake with nuts in it. She admitted it did despite the fact that he was allergic to nuts. She was hoping it would postpone the execution so she could save him. Garret explained the reaction was to the cake. Renee came to see Garret and she said he won. Garret was worried about his career where as Renee was not. Garret said he still doesn't like her but it appears they will continue their relationship.
Renee hooked up with Garret in season 2 and subsequently broke it off again at the end of season 2 (Pandora’s Trunk) but they were together in season 3. She and Garret have always had an odd relationship. They push each others buttons, constantly driving each other to the limit. Renee tries to get him to take her side, but usually he’ll stick up for his crew (usually because they’re right). Renee is bothered by how Garret deals with Jordan. She thinks he lets her get away with murder—or close to it. She’s accused him on more than one occasion of letting Jordan walk all over him. Renee is a third generation lawyer (her grandfather and father were both lawyers). She was married to a man named Eddie, but is now divorced. She and her husband tried to have children, but couldn’t conceive which eventually led to the downfall of their marriage.
Renee showed up in 2004 (the fourth season) pregnant with her ex’s baby, (I question if it’s really his, especially since she and her husband couldn’t seem to conceive when they were married.) That really put a stop to their (Renee and Garret) already ‘almost over’ relationship. Garret still cares for her though. And sparks still fly when they’re in the same room.
