Severus Snape leaned back in his chair and let out a heavy sigh; sitting there, alone, he had come to the realization that Dumbledore, the apparent genius that he was, had left the fate of the wizarding world on the shoulders of two men. The first being himself, a man few people trusted, and the second being seventeen year old Harry Potter.

The raven haired man had spent many months pondering the plan devised by Dumbledore and the more he analyzed it, the less he liked it. He knew exactly what would have to be done and he knew he would pull through but what if Potter backed out. Should he have the same faith, mostly blind faith, in the teenager that the late headmaster had? Should he let his own life be taken in just a few days in hope that the boy would follow through with what he had to do in order to kill Voldermort?

Severus did not approve of Dumbledore's plan, not just because Potter might back down but, because Harry had been saved and groomed his entire life by Dumbledore for that single moment. Dumbledore had raised a pig for the slaughter…

He closed his blackish-brown eyes and shook his head in disgust. The man that everyone had looked up to was simply keeping the boy alive so he could die at the right moment. As disgusted as he was by this Snape understood that there was no going back, there was no more options, this plan was so far unfolded.

The current Hogwarts Headmaster picked up a quill and dipped it into a bottle of black ink. He knew his days were numbered and he still had a lot of explaining to do…

Take it.… the last few words of Severus Snape burned in Harry's mind as he ran up the staircase toward the Headmaster's office. "Albus Dumbledore." Harry watched as the gargoyle began to shift. He quickly made his way into the headmaster's office and followed Snape's instructions to dump his memories into the pensieve. He watched, shocked, as years of Severus Snape's memories unraveled before his eyes.

When Harry was standing, once again, in the Headmaster's office he looked around the room. All of this time he had believed that Snape was a traitor, now he knew otherwise, but it was too late.

Harry pulled the envelope out of his robes and looked at his name scrawled across the back in tiny, cramped handwriting. Harry slowly opened the letter and unfolded the piece of parchment. He took a seat at the headmaster's desk as he began to read:

Harry,

I know there is too much to explain and it will never all fit into a letter. I decided that I will do the best I can because I simply cannot die without telling you this. I'm sorry. I'm sure that sounds strange to you, I'm sure you've always believed I hated you and I did. I hated you for all of the wrong reasons and I am sorry for that. I hated you for who your father was, for how much you resembled him. I held my grudge against your father against you as well and that was wrong of me. I know you are probably a long way away from forgiving me Harry but if you have followed my directions and you have already viewed my memories things may be clearer for you.

I've always loved your mother Harry. Lily, she was my best friend, the one love of my life and she fell in love with my enemy. She married your father, a man who I despised, and then she had you. You can see that I tried to protect her… to protect both of them and that failed. I'm sorry for that. It is my fault and I can't bring them back, no matter how much I would love to have the opportunity.

I'm sorry you never got the chance to know her but the more I watch, and don't be fooled I am still watching you Harry, the more I see of her in you. That is the one thing that Dumbledore said that is actually true. I do not agree with any of this, you need to know that. I feel for you Harry, but know that many have died for this cause.

I know how hard it is going to be to walk up to Vodlemort and die at his hands. In a few short days I will die at his hands as well. If I had never told him of that prophecy you would be safe, with your mother and your father, alive and well but maybe Voldermort would have taken complete control and more would be dead. There are a lot of what-ifs in life and I have been thinking about many what-ifs lately.

There is one thing that cannot happen Harry, you cannot back down now. If you do not go through with this everyone will die, Hermione, Ron, the order, your schoolmates, your friends, your friend's families. You are their only hope Harry.

Just remember that when you are going out there that you are saving so many lives. Think about how proud your mother and father would be, they died protecting you, they died for this cause too. Think of how proud your god-father would be and Dumbledore as well, don't let them die in vain.

And think that I will be proud as well.

My hate is gone and I wish I could have told you all of this in person but it was impossible.

Be brave Harry, we are all counting on you.

~Severus Snape.

Harry read the letter over again, his green eyes pouring over the page as a tear rolled down his cheek. The raven haired boy tucked the note into his jacket and took in a deep breath. He knew what he had to do; too many people had lost their lives for him and now was the time for it to end.

A/N: this was not my best, I still like it andI did enjoy writing it. I always felt that Snape should get more credit than he did so when I saw this prompt I had to write it this way. I know it's a bit of a stretch but pretty much the point was Snape had to tell Harry how he felt and explain everything before he died so he wrote the letter so Harry could understand. That was what Snape had to do with his last day. Hope you enjoyed it : )
