Peter walked through a door, and, suddenly, he was in Ark's club. This was odd, as the door was not the alleyway entrance. This earned a mental shrug from Peter. In the poor lighting, he thought he saw Ark and the white-haired girl.
"Hello there!" Peter said, "I'm back!" Then he paused, puzzled. The one he thought was Ark... wasn't.
"Are you... Ark's sister?" Peter asked, walking across the dance floor.
