After all the stuff with his parents, about his mother being pregnant and stuff, and talking to his sister, and making a new friend, Alex walked around the train, his sister had already made friends pretty quickly so she sat in a cabin with them, all the cabins were full, he had just remembered the stuff he had been through, a kid should not have been throught that many things, he was just born with a keen eye for details. He loved solving mysteries, he turned to his parents and gave them his phone, pager, Ipod, and gun. "You carry a gun?!" His dad asked, right at that question, Alex ran into the train, not caring for anything, didn't want to go back home and be grounded.
Alex saw a cabin with two kids, one his age and one younger than him, "'Scuse me, can I sit here?" Alex said peeling his head in. Waiting for an answer from the two kids. He had his clothes and stuff ready for Hogwarts.
Alex had left his stuff in that Cabin and went to walk to people he knew, he then saw Cecilia, "CeCe!" He said that's what he called here.
