Mum,
he is here. The Dark Lord. Well, at 17. I'm not sure what you thought of him back then (positively?), but while I do not want to explain the entirety of why, he is - in 1996 - not in our family's interest. You and Father and I all knew that. Bella's probably the only one in our family still in favor with him and having an interest, though I don't know. I didn't talk with her much recently about it. Since we...weren't sure.
Anyway, don't breath a word about this to anyone, not to your sisters, not to Father if he shows up, no one but me. I don't trust that it will not go extremely life threateningly bad if you do. We could all die, in fact, should you tell anyone.
I don't know what to do, and I suppose we'll need to have a very long talk about your future, but please mother, be extremely careful around him. And even if from your time, he seemed the right choice, it'll be the death of us, I fear.
