She again draws her weapon in the background while Raylan catches and keeps Dean's attention leading to a non-violent capture of Dean and recovery of Loretta. As Raylan is talking to Loretta McCready in the trunk of the car, Rachel warns him that Dean is coming back. Raylan approaches the car while Rachel covers Dean who has gone to pay. While in the car with Rachel Raylan gets a call from Tom Bergen with information on Dean's whereabouts they arrive at a gas station where he is filling up his car. The situation is resolved without bullets. Rachel quitely draws her weapon during the exchange and calmly replies to Raylan that she will shoot Coover if Raylan will take a step in either direction, implied so that she gets a clear shot. When told that Raylan is a 'federal' Coover throws the rat at the marshals' car and proceeds to make veiled threats. Coover is shooting rats out-back during the first part of the conversation, later appearing with a dead rat in one hand and his hand-gun in the other. Dickie admits to having hired Dean and says that he left recently. The two marshals next visit Dickie and Coover Bennett's house Raylan takes point in the discussion, with Rachel staying in the background close to the car. Rachel and Raylan follow up on this by visiting Mags Bennett's store, where she denies any knowledge of or association with Dean. Bergen realizes why when Rachel mentions the name of the company Dean works for, identifying it as owned by the Bennet clan. Kentucky State Trooper Tom Bergen joins them when they question Walt McCready, who denies having called the state tip line despite Bergen telling him the call was registered with his name and address. In The Moonshine War Rachel asks fellow deputy marshal Raylan Givens to accompany her to Harlan on her trip to investigate a tip about the child molester James Earl Dean being seen talking to a young girl at the McCready place. She tries on his hat one time and says it doesn't fit. In particular she notes Raylan wearing his hat everywhere on the job. Later she comments that white males get away with much more rule-breaking than she does.

However Raylan keeps taking charge against her wishes. Rachel is assigned as the lead on a case that sends her and Raylan to Los Angeles to find an old fugitive. It's revealed by Art Mullen in the Season 4 episode, ' Where's Waldo?' that Rachel left her husband prior to the events of the fourth season. Despite the high tensions surrounding her job, she is always calm, level headed, and takes her orders seriously. After an auto-accident in which her sister was killed and her brother-in-law survived, Deputy Marshal Brooks took in her nephew and raised him with the help of her mother. Despite these added responsibilities, Rachel finished high school, went to college at Ole Miss (University of Mississippi), and eventually joined the Marshal's Service as a Deputy US Marshal. The oldest of two sisters, Rachel was always left as the emergency parent for her younger sister while her mother was out working. Rachel spent her childhood in Hendersonville, Tennessee, raised by her mother after her father died of cancer. Not much is known about Rachel other than the tiny bits of information given throughout the six seasons.
