She's a pretty bitter person, especially due to her two sisters, Ruthie and Natalia, being so doted on. He has always acted out in an attempt to be noticed, and carries this attitude deep into adulthood to the point he cares a little too much about how she comes across to people. Additionally, she struggles to keep relationships, and due to said loneliness, always notices things happening around her. Also a massive newspaper hoarder due to her nosiness.

You can imagine for these reasons its gonna be a challenge for her to face her sister, let alone solve the murder.
