As soon as the train arrived at Hogwarts, the students took boats to the castle. Once they arrived, to Harry's surprise, Hagrid greeted them.
It's Proff. Snape, head of Slytherin house.
Next was The Sorting Ceremony, but before that, the new students met Proffecer McGonagall and Headmaster Dumbledor. Harry heard from Ron that he wants Gryfinndor, the brave house, not Slytherin, the powerful and thought of as evil house.
Wow!! Look at all this Ron!
I've never had a Christmas like this!
Happy Christmas Harry!
Harry, Ron, and Hermione were sorted into Gryfinndor, and Harry and Ron settle into their dorm which they share with three other boys, Dean, Seamus, and Neville.
Going back to The Great Hall, the trio find Snape and McGonagall arguing, and Harry learns of Snape's existence.
No wonder. He even looks evil.
On Christmas morning, Harry wakes up to a surprise, presents on Christmas! The Dursleys never gave his anything of the sort.
During a detention assignment, Harry and Ron come across something terrifying. Proff. Quirrell drinking unicorn blood.
