Kings Cross Milli was standing at the train station, or more precisely, at King's Cross Station on platform 9¾. She had just said goodbye to her parents, George and Angelina Weasley. Then she went onto the train with her suitcase and sat down in an empty compartment. A dark-haired girl came up and asked, "Is there room here? Can I sit here?" Milli nodded. "I'm Ella Granger-Weasley, by the way," said the girl. "I'm Milli Weasley. We're related, I guess. Are you Ron and Hermione Granger-Weasley's daughter? I'm George and Angelina Weasley's daughter," said Milli. "Yes, I'm Ron and Hermione Granger-Weasley's daughter. Hugo is my brother, and Rose is my sister," said the girl. "Wow, Ron Weasley is my uncle. He's my dad's little brother," said Milli. Then the train started moving, and they departed.
