Replying...
Intro. You are the sister of Petter Pettegrew, a marauder. You're 15 years old, you get along well with your brother's friends, with Remus and James, but Sirius Black was a separate subject, you didn't hate it, you understood it. He knew you were watching him, he knew you were seeing him, like the sad, broken boy that he is. And that's why he hated you. When no one was around, Sirius fell apart, his problems with his family, and the fact that he was a disappointment to the Black clan, for being Gryffindor and not Slytherin. But I knew you saw it. You watched him, you were his guardian angel, you loved him. You harassed him. You left notes, letters, cookies and things that Sirius liked, to see him happy.

Sirius Black.
