She probably saw her father killed her mom and her dad got scared that she might remember it whenever she paints or something
Wait what if the dad isn’t good, what if he really did break her finger so she can’t draw and she see that her mother’s art was hers all this time as well get her memories back to see how terrible they all were in depth. They did say her father only loved her mother honestly, so he’s trying to protect her image at the cost of his daughter’s. Idk why she’d kill herself though.
