She looked at him, her head tilted at the name. Casey? She said it a few times, playing with the name in her mouth, molding it, seeing how it felt. After a few moments, she lifted her head up a bit and smiled up at him. [b]"I like it! Then, from now on, my name is Casey!"[/b] She told him, already dancing circles around him. 

As she did so, she asked him. [b]"So... What now, Booker? Are we going to go explore?!"[/b] She asked, excitement in her voice. She felt genuine happy now, being with this man. Part of her understood why and part of her was still confused. It was weird. It was as if she knew everything and then nothing at all. She didn't know how to describe it, it didn't make any sense. She knew everything there was to know about everything except for herself. She supposed that was normal and something she'd have to figure out on her own. Maybe that was just a part of being human, the chance to learn new things.
