SCORPIUS
I’m still the child of Voldemort, without a mother, giving sympathy to the boy who doesn’t ever give anything back. So I’m sorry if I’ve ruined your life because I tell you – you wouldn’t have a chance of ruining mine – it was already ruined. You just didn’t make it better. Because you’re a terrible – the most terrible – friend.
Scorpius to Albus
