Sirius: Hello Harry Potter. Curious name you have there. It just so happens you have the same last name as Prongs over here,

Prongs: Padfoot, old friend, I thought we all agreed to keep our names secret. We don't want this person knowing about the great power we possess.

Remus: Would you two stop? Prongs, I don't think it's very wise to be talking openly about any great powers if it's supposed to be secret. And Padfoot, shut it about Prongs's name.

Harry interrupted, "Oh, I know your names, you don't have to worry."

Sirius: He can't! You didn't tell, did you Prongs?

James: I would never! How dare you accuse me of such a thing!

Peter: By the way, who in the bloody world is Harry Potter?

Harry hesitated before answering, "Er. me."

Sirius: Who are you?

James: Padfoot, I think we've covered that already. He's Harry Potter.

Remus: Yes, Prongs, we all know that. But have you the slightest idea who Harry Potter is?

James: No, Moony. But I don't think you have the slightest clue, either.

Sirius: Why don't we ask him, then?

Peter: I thought I already did.

Harry found this conversation very amusing, even if he didn't have to say anything.

James: So, anyways, Harry, - I always liked that name.

Remus: Get to the point, Prongs.

James: Oh yeah, who are you?

Harry grinned, "I'm you're son"

Sirius: Ha! It's like Star Wars backwards!

Peter: What in Riddle's name is Star Wars?

Sirius: Oh, it's this muggle movie that just came out.

James: Uh, Wormtail, what exactly do you mean by 'in Riddle's name'?

Remus: Who's Riddle?

Peter: Er. nobody.

Harry frowned, "Peter's a traitor! He's in league with Voldemort, and he sold you're whereabouts to the Dark Lord, and he killed you!"

James: Killed who?

"You!" Harry cried to the map.

James: I'm dead?

Sirius: Well, technically you're in a map.

James: I am?

Remus: Wormtail, is any of this true?

Peter: *ink smudge*

James: Woah, woah, woah, wait a minute. I have a son?

Harry nodded, "Yup."

Remus: Who's the mother?

James: er.

Sirius: This is fun!

Meanwhile, Harry was debating with himself whether or not he should tell them.

James: er. yeah. who's the. er. mother?

Harry smiled, "Lily."
