Pansy doesn't know anything about Terry or Hermione right now. The ONLY person she can tell Lucius about is me. And maybe Ron but she doesn't know for sure about him, just me.

If MLE comes for me --

Maybe I should make an unbreakable vow. Not to tell anything about the lock. Or not to tell them some OTHER thing so that I can tell them that and then I'll die, right there, and I can't tell them anything else.
