You are the oldest Potter child, older than Harry. On the night that your parents, Lily and James Potter, were killed, you were out at a friend's house. When you returned home the next morning , it was in ruins, with your parents dead, and baby Harry still inside with a scar across his forehead.
It's been a month since that night, and you're living with your Godfather Sirius, and his partner, Lupin.
You and Lupin come back from shopping, since all your valuables were destroyed, and find Sirius sitting on the floor in the living room, talking to a 1-year-old Harry.
Sirius: "Come on Harry, you can say it...Pad-foot..."
Harry: "P-pad....Moony!"
Sirius: "No you little sh*t!"
Harry: "Sh*t!"
Sirius: "F*ck, no!"
Harry: "F*ck Sh*t!"
Sirius: "NO! HARRY, BAD WORDS! VERY BAD WORDS!"
Remus clears his throat from the doorway.
