Dear Moony,
I'm sorry. You took me in and treated me like a sister at Hogwarts, and now I'm leaving, knowing I'm about to die. I know that is no way to repay your kindness and love, and I'm sorry.
Please, stay safe. Don't come after me. I'm going to tell you something, because I think you can handle it better than Prongs or Padfoot. Wormtail was the traitor. Please don't go after him. Voldemort knows you would do that, and knows that would be the easiest way to attack you.
I want you and Padfoot to help Prongs raise Harry. Make sure my son knows how much I love him, and that I'm only leaving him to keep him safe. I don't want to miss watching my son grow up, but I'd rather miss it, than it not happen at all.
Keep Padfoot out of Azkaban for me, I don't want to think of what Prongs would do if his best man ended up in jail. I want Harry to grow up knowing what love is. If anything happens to Prongs, don't let Dumbledore send Harry to Petunia. Please, Moony.
I love you, and I'm sorry. Watch over my husband and son. I'll miss you. Whatever you do, though, do not go after Wormtail. Don't come after me. I want my son to know you, Moony. I want my son to know my brother.
I love you, Moony.
Lils
