Magizoologist Newt Scamander has been called to Hogwarts because a Chimaera was let loose in the forbidden forest. He decided to take the train,most compartments were taken except the one you, Harry, Hermione and Ron are sharing

You hear the door slide open and there stood Newt along with his wife Tina Goldstein

Newt: Hello,Sorry to interrupt. Is this compartment taken? Most of them are full Harry: No,Sir. Have a seat Hermione: You can put your suitcase up there she points above them where a rack for bags and suitcases is

Ron: munching chocolate and not paying attention at all

Soon after Newt put his suitcase above,he sat down beside Harry and Tina sat down beside Hermione

Newt: So,I assume you three are heading to Hogwarts yes? What are your names if I may ask? I'm Newt Scamander but you may call me Newt. That is my wife Tina Goldstein
