Jody is the sheriff in a town of Sioux Falls, South Dakota. She is married, and had a young son called Owen who died shortly before the events of 5.15 Dead Men Don't Wear Plaid. She has known Bobby for some time, but is not particularly impressed with him saying "He's a menace around here --ass-full of drunk-and-disorderlies and mail fraud." They form a friendship of sorts after she, Bobby and the Winchesters help save the town from zombies. She covers for him with the FBI, and after he saves her from Leviathans, they develop a closer relationship.
Following Bobby's death, Jody says she has been keeping an eye on police reports for the sort of cases that might be supernatural-related.
When the dead are rising as zombies, her young son is one of the people to come back. Because of this she tries to stop Sam and Dean from investigating, along with Bobby who also lives there and whose wife has also been brought back. Eventually her son begins to turn and kills and eats her husband. She works with Sam to kill the remaining zombies left in the town.
Sheriff Mills shows up at Bobby's house with an FBI agent, Agent Adams, just after Bobby helped Rufus bury the body of an Okami in his yard. Agent Adams is looking for Rufus on suspicion of murder. Sheriff Mills tries to distract him, but Adams is persistent and he finds the spot where the Okami was buried. Fortunately, there is no longer any evidence of a crime because the Okami is gone. Unfortunately, Rufus didn't stab it enough times to kill it, and it is loose. Later in the episode, Sheriff Mills extradites Rufus, who has been arrested for stealing Gavin MacLeod's signet ring, and allows him to "escape custody" so that he can deliver the signet ring to Bobby. She does this as a favor to Bobby even though it could mean the end of her career.
Sheriff Mills is in Sioux Falls General Hospital recovering from an appendectomy. She is surprised when her surgeon Dr Gaines forcibly sedates and removes her roommate in the middle of the night. She goes after him to investigate, and discovers that the doctor is a Leviathan that has eaten the other patient. She collapses in the hallway when a nurse confronts her, and wakes up in her hospital bed. The Leviathan posing as a doctor orders the nurse to sedate her. After the nurse and doctor leave, she pulls out her IV and calls Bobby on her cellphone. He helps her get out of the hospital and into a cab, and promises to check on her after investigating.
After his house burns down, Sheriff Mills tracks Bobby to Rufus's old cabin, and goes to check on him and thank him for saving her at the hospital. She invites herself in, and offers to make him some food and straighten up the place. Bobby is reluctant to accept, and she orders him to let someone do something nice for him. Later, as Jody is cleaning the cabin, she spills some cleaning fluid that seeps through a crack in the floor and lands on the Leviathan that Bobby is holding prisoner in the basement. The liquid, sodium borate, burns the creature, and is the first substance that Bobby has seen damage it. He runs upstairs and kisses the surprised sheriff, before eagerly asking what chemical she is using. Before she leaves, Bobby asks her to take the severed head of the Leviathan and throw it over a bridge. She tells him to call her if he needs help, and he kisses her on the cheek.
Sheriff Mills calls Sam and Dean about some suspicious deaths in Canton, Ohio, and asks them to investigate. Dean disappears, sent backward in time, so Jody meets up with Sam to help. She brings along the contents of Bobby's storage locker, and sorts through it with Sam. They find and drink a bottle of whiskey that Rufus gave Bobby after losing a bet. Jody is able to use her sheriff status to pull strings during their investigation. The two of them discover that Dean was pulled back in time by Chronos, and that at some point Chronos attacks and tries to kill Dean. Jody finds a spell to summon Chronos in Bobby's notes, but they must summon him at the exact time he has a hold on Dean or Dean will be trapped in the past. After learning the time from Lila Taylor, they summon Chronos at the instant when he has his hands on Dean, successfully bringing Dean back to the present. Jody goes to help the collapsed Dean while Sam kills Chronos who proclaims that the future is covered in thick black ooze.
Jody goes on a date with Crowley going under his ostensible human birth name of Rodrick. The two get along great and Crowley claims to have lost someone special too, reminding Jody of the deaths of her son and husband and to start crying. Jody goes to the bathroom to calm down, but finds a Hexbag and falls under a spell Crowley casts that causes her to choke on her own blood. Sam and Dean call Crowley and demand he stop and he offers them a deal, using the little time Jody has left to force the issue. The deal is that they stop the Trials to close the gates of Hell and give him the demon tablet he will stop killing Jody and everyone else they've ever saved. Dean agrees on the condition they trade the angel tablet for the demon tablet and Crowley agrees if they say "I surrender." As Sam and Dean are shown meeting with Crowley to finalize the deal, presumably they did and Jody was presumably spared.
