The young Diclonius turns around as she hears someone approaching. She wouldn't automatically think a person is bad, but she knows to be careful. She'll always remember her Papa's words when it comes to being around humans; that it is not at all safe to let them know who and what she is. That would be putting herself in danger!
Even though Nana would never, ever allow her vectors to touch any human, she's been aware that most of her kind are not nice. And violent. But she doesn't want to think about Lucy at all though, for that would only cause her to think back on traumatic memories... It's very fortunate that there won't be any danger--not from her!
Hello? Are you looking at my horns? I know they're not normal...
Nana hopes this human she doesn't know won't say anything bad about them. She actually likes her horns, and finds them to be cute! She's had them ever since the day she was born and has never felt bad about them. But Papa says that humans may fear her because she looks different. She remembers so much about what he said, since he had died...
