Throughout Legacies Series
In I'll Never Give Up Hope, Mac sits next to Alaric at the bar. She sees him writing forensic notes and wonders if he's a detective. He lies and tells her that he's a True Crime novelist. As Josie enters the bar, the bartender tells Alaric that she can't be there as she's underage, but Mac flashes her badge and tells the bartender to let him talk to his daughter.
In You Remind Me of Someone I Used to Know, Sheriff Mac drops off her kids, Ethan and Maya, at school, only to find Hope Mikaelson standing next to a vandalized exterior wall. She suspects Hope as the culprit at face value, but Maya is quick to defend her. Even though Ethan and Maya are embarrassed to be dropped off in a cop car no less, Sheriff Mac is there on official business — to see Principal Saltzman.
In Alaric's office, she questions him about the disappearance of Dennis. She informs him that his teammates last saw him at the Old Mill, by the Salvatore School, to which they found his abandoned truck and his hunting rifle nearby. Alaric brushes it off, as he's still getting to know his students and her, but he'll check with his classmates and teachers. Sheriff Mac mentions that her biggest concern was a rash of missing dogs up to this point and Alaric, jokingly, suggests that the two could be connected.
Later during the annual charity football game between the two schools, Sheriff Mac arrives to inform Alaric that Dennis turned up, a little hungover, but safe and sound. Alaric tells her she's arrived just in time as Ethan has joined in the game. To her and Alaric's horror, Ethan is injured mid-pass on account of Josie's magic, and he collapses to the ground. They transport him off the field to Mystic Falls Hospital to contend with his injuries.
In Since When Do You Speak Japanese?, Sheriff Mac hands Alaric a restraining order against him filed by Rupert Vardemus, alerting him that he isn't allowed near the school. She leaves her bag, and later that day, Alaric looks through it — believing it to be Josie's — and finds files on him. He questions her about it, and she tells him that she likes him and wanted to make sure he was a good guy.
In That's Nothing I Had to Remember, Sheriff Mac arrests Alaric Saltzman on suspicion of the crimes that occurred at the Mystic Tap; she is unaware that it was actually Ryan Clarke who is to blame. She tells Alaric that he has a complicated history, especially when it comes to woman as the majority of his partners are dead. Alaric reveals that things in Mystic Falls are weird, but she too has a complex background, revealing that he looked into her. After questioning, Alaric eventually hands her Matt Donovan's card, telling her to ring her and check out his alibi.
When she returns, following the spell that restored everyone's memories, Alaric reveals to her that supernatural creatures are real. He asks if she can be the one to turn a blind eye whenever he needs her to, however she tells him that she cannot. With this, he has Kaleb compel away all he has told her and everything she knows about the supernatural.
In This is Why We Don't Entrust Plans to Muppet Babies, Sheriff Mac meets up with Alaric at Mystic Tap. Alaric is having trouble with his novel and asks for her advice about defusing a bomb. She offers that his character could just blow the bomb up, as that generally the render-safe protocol for any explosive. Detonate it from a distance. That's how things were done in the EOD. That's not the answer that Alaric was hoping for, but the conversation changes when she receives a phone call about Ethan. He's landed himself in detention for a fight involving another bully. Alaric tells her that he's a good kid and believes that he was sticking up for someone smaller. He confides in her that he wishes Lizzie would date somebody like Ethan. Sheriff Mac questions what happened to the exchange student, Sebastian. Alaric explains that he wasn't right for his daughter and he had to let him know it. She jokes with him about the possibility of murdering him and Alaric laughs it off.
Later that night, she receives a phone call from Alaric. He wants to thank her for the advice. She asks if he's finished his novel. He hasn't but he decided to let hi daughters take care of their situation and to his surprise, the world didn't end. He owes her one. With that, he asks her if she'd like to have dinner that weekend. She tells him that she's already answered him and it's in his pocket — a drink coaster that says "you're da bomb".
Sheriff Mac is described as a single mother and career woman "who stands as the human line of defense in a town regularly besieged by monsters. Despite a troubled past, she's willing to open herself up to a new romance when the opportunity arises."
