Who is this guy? Serenity thought. 

"Sure, but I don't even know your name. I'm the White Guardian, but you can call me Serenity." She said. She held out her hand. She didn't get the sense that he was mean or a bad guy. She smiled and followed him to get ice cream. She was excited to be meeting someone new, making friends was a great way to settle in. Plus she was glad to get away from the large crowd.
