Note Conversation between James and Sirius November 1 during Herbology. It's note-taking day:
J: Discussion Time.
S: What's to discuss? The map is finished as far as we know.
J: Key words: AS FAR AS WE KNOW! Do you really think this castle is just normal? Not a chance.
S: Oh yes and how will we figure everything out then? We're not exactly geniuses.
J: Damnit Sirius! That hurt… I'm as good a genius as anyone!
S: Yeah, anyone under the age of 4.
J: ANYWAYS: You know that absolute clown house we found on the 7th floor? Well, I went up to measure it and put it on the map and it wasn't there!
S: Come on.. Stop pulling my leg.
J: I'M NOT!
S: ARE TOO!
Note Conversation continued after James smacked Sirius in the back of the head:
S: Fine… I'll go up and look for it with you.
J: Cool.
Remus's Diary entry 10:00 November 1:
So, James and Sirius dragged me to the 7th floor to see the madhouse I wrote about before. AND IT WASN'T THERE. James started pointing to the wall and screaming, "I TOLD YOU!" Sirius was floored. He looked bewildered at the fact that James was right. I start pacing back and forth for a bit saying, "Well, how are we supposed to find out what's up with the door."
James goes, "We could ask a teacher…"
Sirius interrupted him saying, "Idiot… like that would work out."
"Not if it's Dumbledore," claimed James
"We need to consult with a book first about this room…" I said that and that's when the door popped up! James and Sirius and I all exchanged freaked out glances.
"Well," said James. "Are we going in or are we just going to stare?"
And then we all clamored into the room to find a small room, with one table in the middle. On the table there were three books. One was in French, the other in an odd language I didn't know and the last was in English. It was called, Disappearances by Zelda VanWinkle. James and Sirius just stared as I picked up the book… It was all about things that disappear!
Excerpt from Disappearances by Zelda VanWinkle that reveals a whole lot to the trio:
Some castles in Finland, Sweden, Norway, Iceland, and few in England have disappearing doors. Some of these doors are of rooms only privy to beauties and some only to the owner of the castle. These are the most common in disappearing rooms. In the famous Hogwarts castle there is one room known to few students and teachers as the Room of Requirement. It only appears when someone walking past needs something.
Note Conversation between James and Sirius on November 2 during Potions:
J: Well… glad we settled that…
S: Yep.
J: Oh my God! I just had a brilliant idea!
A/N: Heh… well sorry for the cliff hanger. Luckily no one blabbed about the Room of Requirement. I wish that had had more jokes… but hey how much funny things can you do when you're listening to the Killers? The word killers just depresses me.
