"Voldemort murdered Lily and James? I'LL RAISE YOU, HARRY." "Peter was camping out in your dorm for three years? I'M COMING, HARRY." "Your scar hurt? I'M COMING, HARRY." "Someone put your name in the Goblet of Fire? HOLD ON HARRY, I'M STAYING IN THIS CAVE DON'T WORRY I'LL TAKE CARE OF YOU." "Snape might mistreat you in Occlumency lessons? TAKE THIS MIRROR SO I KNOW WHEN TO BEAT HIM UP." "You're in the Department of Mysteries? I'M COMING, HARRY." And after that, Sirius never came for Harry again.
