She pretends like everything is fine as they grow closer and closer, all while working to secure evidence of the murder and trying to get Kairi to tell her the full details of what happened. He's reluctant, worried that she won't be able to see him the same way ever again, and she doesn't press him. But after an emotional incident at the supermarket, she senses he's vulnerable. Rize isn't prepared for what she hears.
