You can hear them talking

You remain downstairs by the door and you can hear Kendra going upstairs to find Alexa. You hear a door open and Kendra and Alexa's voices. You can partially make out what they're saying, especially when either of them raises their voice.

You hear a few words Kendra say. "Hospital" and "doctor" are mentioned a few times by her.

"Yes! He's very good and he made me feel better. He's here?" Alexa sounds excited.

"Wait, hold on," Kendra says firmly. "Tell me about your visit earlier." Then their voices become too soft for you to hear anything clearly and you're starting to get nervous. What if Alexa tells her sister that you took advantage of her? She didn't seem to mind, and while she certainly is not bright enough to understand that, her sister does not appear to be the same. The conversation continues on for a few minutes and you starting to wonder if you should use your magic rings to find out what's going on. You could turn invisible and go upstairs to spy on them, although you've already missed a lot of their conversation. You could stop time too, but you're not sure what that would accomplish. Maybe you'll have to use your mind control ring to erase their memories of you.
