Tattletale is a freelance informant with an end goal of hunting down her brother’s killer.
She adjusts her “personality” to her situation, and comes off as easy to talk to. She is a psychopath with a lack of empathy, and manipulates people for her own benefit. 
She always steers the conversation in her favor, and manages to learn a large amount about people in a small time frame. 
She has a soft spot for kids and animals
She can find information on literally anything. She is obsessed with it.
