Audrey Parker, a former FBI agent, came to Haven on a case and stayed when she realized her mysterious past was wrapped up in the history of the town. Audrey's an antidote to "The Troubles" - the super powers that plague the residents of Haven as more curse than blessing. Every time "The Troubles" appear, Audrey (or some version of her - Lucy Ripley in the 1980s, Sarah in the 1950s) appears to help - never with a memory of her past in town. Despite a nature geared towards helping people, Audrey's no pushover. She's tough and spontaneous, and willing to rely on instinct rather than planning. In many ways she's the opposite of her true love, Nathan Wuornos - who's practical and by-the-book - but that's why they make such a perfect pair.
