Cora

She is described as the introverted type. She has an inclination towards observing. Calm and composed, she carefully studies the whole of the Veyrun town website before taking action. Her spoken output is sparing, but when she does speak, her statements are either surprisingly astute or refreshingly blunt. She's the first to notice the section of the library that's been covered, the misaligned street signs, and the repetitive dialogue.. Fiction is her comfort, and she has a natural gift for detecting hidden patterns, while pretending that she is simply "looking for something to read.” 

BACKGROUND: She always had a way of noticing things that the others didn’t, like the way the sunlight hit the window at exactly 3:12 p.m. every afternoon or how a certain book on the shelf always seemed a little more worn than the others. Growing up with her sisters, she often preferred to sit back and observe, finding comfort in the quiet moments when everything felt still. She wasn’t shy, just more focused on absorbing the world around her. Their parents, while loving, were often preoccupied with their own work, leaving the three of them to entertain themselves. But even when they were left to their own devices, she found it hard to let go of the feeling that there was more to the world than what they saw. When they moved to Veyrun, she couldn’t ignore how off the place felt, and something about the town’s oddities intrigued her. Though she doesn’t say much, she’s the first to notice the little things that don’t add up, and the first to silently start connecting the dots

Flaw: She can become so focused on finding patterns that she begins seeing connections everywhere, even when she may be wrong. She also keeps observations to herself for too long.
