Aww, I LOVED this chapter! So touching, so many memories. My favourite part was the one with Petunia, it reminded me of the deleted scene 'You didn't just lose a mother that night at Godric's Hollow. I lost a sister.' Ah, why did they cut that?!? Anyway, your chapter does justice to the sisters' relationship

Good luck with the rest of your exams! Good thing you could recover your files, I hate it when computers crash...
