To the Honourable Mr Harry Potter

Dear Harry,

I call you honourable because your friend says you're nothing like your dad. She says you're going to be modest. I hope that isn't some futuristic euphemism for 'boring.' I can't imagine the son of James Potter being modest, but hope springs eternal. And if I have anything to say about it, you will not turn out boring. But I'm guessing by the way she hasn't mentioned my future the way she mentioned Remus being your teacher or James and Lily marrying that I might not be a very big part of your life despite what James tells me.

Let me say now, here in 1977, as young and stupid as I am, there's one thing I know for sure and it's that I want to be a part of it. Whatever happens to me that keeps me away from you, just remember that it wasn't by choice. I would never turn my back on James or any son of his. You and he are my family and I love you both. Whenever you need help, just call me and I'll find a way to be there.

Maybe she just didn't say anything to keep us from fucking with the timeline. Remus seems to think that's what it is, but I see the way she looks away when James or Peter or I ask about the future. I know something is going to happen. Maybe it already has and this warning will come too late, but be careful. I would die to protect you and your dad, but I may not have the opportunity to prove that to you.

In case I'm not around to be a bad influence on you, let me tell you a few things about your dad. He got so scared in his first Quidditch match against Slytherin that he shat himself before the game. He also ran away from the first girl who tried to kiss him, Danielle Hodgekiss, remember that name. And he cheated on his History of Magic exam third year. He copied his answer off of Remus and still got points taken off for his miserable penmanship. Also, remember to ask him about The Niffler Incident. That one is very important and embarrassing. I've been forbidden to tell you about it, but you can still ask him for yourself.

Evans is so blunt about your dad's shortcomings she's probably already told you how long it took him to win her over, but I'll assume she's gotten nicer over the years. He spent nearly three years chasing her down the halls of Hogwarts. She hexed him five times that I know of and levitated him into the lake twice. It took your friend to help him get the girl. I don't know if that counts as tampering with the timeline. Maybe she was meant to come back here to make sure you were born.

About your friend, she's a keeper like Remus, clever and dead reliable. She'll keep you out of trouble, which if you're even a bit like your dad will find you even if you don't want it to.

There's more I would like to say to you, but I'm going to hold on to it in the hope that I will be a part of your life. Maybe now that I know you're coming, I can help prevent whatever it is that comes between us Marauders. I want to be there for your first day at Hogwarts and all your Quidditch matches. I don't want to miss a moment of you.

Remember that I love you and I can't wait to meet you.
