Hydra, a few of the Order members know you went missing today. I'm sorry, we didn't want to violate your and Justin's privacy, or blab about what's said under this lock, but we had to let Mr and Mrs Longbottom know. In case--well, we didn't know exactly what your father had discovered. And we told Nymphadora Tonks, so she could write to you, so your father would realise he couldn't make you entirely disappear.
