Karen is 23 and quite extroverted, but she is smart enough not to speak to just anyone. She doesn't know much about the current situation in Arefu and constantly finds herself at odds with Evan King. She likes to wander around outside her house, even at night, and does it almost defiantly to tick off the mayor. She doesn't believe that living in constant fear is the answer. However foolish this might be, you have to admire her guts.
She stays in her home all day, unless the player has finished the Blood Ties quest and has selected the option for Vance to provide the town with security. Then she will be seen wandering around Arefu more often.
