Stranger: Lily,Its Severus…

You: I am not lilly, however I do have here eyes.

Stranger: Mr.Potter?

You: Indeed.

Stranger: And what are you doing up at this hour in the halls?

You: I could ask you the same question.

Stranger: I am a professor, I do not need to tell you of what I am doing, but you are supposed to be tucked away in your bed in your tower.

You: But, you are also dead.

Stranger: Perhaps I have come to haunt the school then.

You: I am not really Harry either, merely first year slytherin trying to find his way back to the common room.

Stranger: Then I suppose I can help you find your way there. I was head of house.

You: That would be most kind of you, I have heard the tale of how you aided in the downfall of He who must not be named.

Stranger: Have you? Just exactly what have you heard?

You: Many things, but never why you suddenly changed sides those many years ago.

You: But, I would gladly here it now if you are willing.

Stranger: -long sigh- You have not learned of the patronus charm have you?

You: -shakes head- merely heard of it sir. I just got my wand the other day. Mahogany, with a walnut handle, 14 inches, and a core of dragon heartstring.

Stranger: A nice wand. Do tell me what you have heard of the charm?

You: That you must have a happy memory for it to work properly. It is used to fend off dementors, and you have to be a powerful wizard for your patronous to take shape.

Stranger: -nods head slowly- Happy…. Tell me….have you ever loved someone so very much with all the being of your very heart and soul that no matter what you did, your very being, your very own magic was affected by that love?

You: -shakes head- I dont think so…

You: Is that what happened to you sir?

Stranger: -stops floating down the hall- Her name was Lily Evans, or as she was later known as, Lily Potter.

You: Lily Potter? The Lily Potter?

Stranger: Yes, the Lily Potter that was the mother to Harry Potter.

You: So, you changed sides because Voldemort killed her?

Stranger: I changed sides before he killed her when I determined that he would likely kill her because of the prophecy I had told him, a prophecy that spoke of his downfall. I changed sides because I knew that he likely would try to kill her son and -sighs once more- She was a stubborn woman and a protective mother I am sure, so she wouldnt just move aside and allow her son to die.

You: -nods somberly-

You: So that’s why you went to Albus Dumbledore…

Stranger: Yes. That is why I went to Albus.

You: You know, he named one of his children after you. Harry Potter I mean.

You: He goes to school here I think. Or at least he did.

Stranger: Did he? Did he really?

You: Albus Severus Potter.

Stranger: How curious that the boy who I was sure hated me for treating him so poorly, names a child after me. -shakes head-

You: From what I’ve heard from the stories, you changed his mind in the end. With your tears.

Stranger: Ah yes..I remember now. Coming back as a ghost, it takes a while for memory to set in.

You: -nods-

You: May I ask a question?

Stranger: Yes?

You: Why did you come back? As a ghost I mean.

Stranger: Let me ask a question first in return. How long has it been since the end of the second wizarding war?

You: lets see…

You: 21 years I believe.

You: I think it had only been 19 years when Albus Potter started his first year at hogwarts, so he should still be here.

Stranger: It has been that long already? Twenty one years in limbo…only to be brought back as a ghost…or perhaps to be reincarnated. I am not so sure of why I am here. Perhaps I am simply here to haunt the school…even maybe beat the Bloody Baron of his post as SLytherin ghost

You: Perhaps your reason just hasnt been revealed yet?

Stranger: It is quite possible. The afterlife has curious ways of working and being a wizard makes it even more apt to be magical.

Stranger: Tell me first year slytherin, you know of my name but I have yet to learn yours.

You: -shakes head embaressed- no sir, I have forgot my manners…

Stranger: Care to tell me your name now then?

You: My name is William.

You: William Barton.

Stranger: And have you been enjoying your first year here at Hogwarts William?

You: Very much so!

You: I’ve already learned so much. Just forgot to pay attention to the stairs tonight…

Stranger: Ah yes, the stairs. It does not help that Peeves goes around messing with things.

You: No, it doesn’t…
