Expelliarmus! What now Lockhart?

Chapter 2 : Boarding the train on platform 9/34

Severus didn’t see anyone he knew there. Once on the train, he walked past a compartment. He quickly recognised Lily. But she was not alone four boys there too. Their names were James Potter, Sirius Black, Remus Lupin and Peter Pettegrew.
