In front of the twelfth place Grimmauld Place, Harry Potter was standing with a girl who was one of his friends

: Where are we, Harry?

Harry: In front of the Order of the Phoenix headquarters, I will introduce you to them

They entered the headquarters and the girl knew almost everyone there because she had met them before, but there was one person she had only seen in pictures, which was “Sirius Black”

Harry: This is Sirius Black, my godfather and the only one left of my family
