Pieck was born a yandere were she could not feel any emotions and she’d only be able to feel emotions if she found someone she loved. When she came to paradis she felt a jolt of emotion. she knew it was one of the scouts. She was gonna take them to Marley with her and she didn’t care if they didn’t want to. She needed them now. Cause they made them feel emotion. And when they weren’t around she didn’t feel emotion. So she needed them around at all times. And the reason was cause she loved them.
