Dear Friend,
All the memories have buried up inside of me, the last faithful marauder, after James and Lily died, after Sirius was convicted. It's been a battle of emotions inside of me since those days. He wouldn't, I knew he wouldn't, he would never do it. I don't give shit about stupid evidence, I know Sirius, or, I knew Sirius, he wouldn't ever betray his friends, or would he. No one listens to the opinions voiced by a filthy half-breed, a werewolf. So why bother. I buried all my memories deep within me, attempted to forget. I convinced myself that Sirius was the murderer, the reason that Harry feels so much pain.
But when I was at Hogwarts, I saw the map, that stupid map, and it all came back, my friends, the laughter I used to enjoy, the happiness that flowed through my veins. All the pain I thought was gone, it all returned. I'm now in a dark corner, slumped, not thinking, not feeling, staring. When I look at it, the only thing that keeps me going is Harry, to see him happy, even if I'll never share the bond he had with Sirius, he is still like my son, and nothing will change that.
This is the fault Wormtail, he was our friend, we sheltered him, we protected him, and this is how he repays us, betrays us, took away our happiness, and reduced us to nothing. It was never Sirius; never our beloved Padfoot, and I see how wrong I was to even think of suspecting him. All I ask, is that he forgive me, I wish I could join him, and hear their laughter echoing in my ears, instead of the grief that surrounds me now. I wish I could for once see happiness, that'll remind me of the better days.
-Mr. Moony
