Here is the rewrite for Chapter 20.

Hermione ended up staying in the hospital wing for several weeks. As it happened, Harry, Ron, Frodo and Sam visited her often. When term resumed, students spread rumors about Hermione's disappearance. But by the time everyone returned to Hogwarts, Merry and Pippin also visited Hermione. Frodo noticed that Aria had about vanished by the time the authors and authoresses returned. He was glad when Anne, SweetDarkSilence, Amy and Abigail showed up. Amy wouldn't stop talking to Hermione, but by then Frodo understood and left them alone.

"I'm surprised it wasn't Lotho," Pippin said, when he and Frodo stepped outside the hospital wing. "We were so close into thinking he was Slytherin's heir. And he wasn't."

"I know." Frodo accepted it the second he was back in Moaning Myrtle's bathroom. Lotho spoke the truth. But then who was Slytherin's heirs, if it wasn't him or Lotho? He waited for Sam, before they and Pippin wandered around the stairs, for exploration purposes. Even though he wanted to complete his homework – no, he needed a break. At least for now.

Harry and Ron also came out, surprised to see the three hobbit boys together.

"Well, we weren't expecting guests," Ron said, jokingly.

"Where's Merry?" Pippin asked, curious.

"He's helping Hermione with some defense against the dark arts homework," Ron informed them.

Frodo started, "Well…"

"ARGH!" It was Filch's voice, coming from the second floor.

"Let's go," Harry said, taking the lead.

"What happened this time around?" Frodo asked, charging up the stairs.

Eventually, and surprised to see that Filch wasn't guarding the corridor, Frodo followed his friends into Moaning Myrtle's bathroom. He learned from Myrtle, with thanks from Harry questioning her, that someone threw two items into the toilet, moving through her head. It was then that Frodo discovered two black covered diaries. One of the diaries looked familiar… of course, Otho's diary. But how… maybe it switched hands for a time. Either way, he and Harry now had two diaries. Only the diary Harry was holding had the name T.M. Riddle scrawled on the first page. Frodo checked his diary, which had the name Mairon on the back cover in gold letters. Now that was curious…

-.-.-

"I told you books are dangerous," Ron said, as he and Frodo visited Hermione with Harry, Sam and Pippin.

"It looks like a blank diary. Look," Frodo said, flipping through the diary's pages.

"Even so, Frodo. I read about a Maiar named Mairon coming to Hogwarts about fifty years ago," Hermione answered. "I found it in Hogwarts: A History book. Only he went under a different name. He wasn't afraid to mention his names, as if he knew what would happen." She added, "There's also a portrait of Mairon, when he was still good. You can find it in the corridor, next to the trophy room."

Frodo nodded. But even by saying Mairon's name, the candles and fireplace flickered. Well, if he was lucky, he wouldn't have to visit the trophy room. And yet the diary… maybe he would have a better look at some point soon. He observed the diary some more, hoping to find something that would show Mairon had written in it. But like the diary Harry had, he couldn't find any answers.

Maybe there was invisible ink on the pages of Mairon's dairy…

When Hermione was better and out of the hospital wing, she, Harry, Ron, Frodo, Sam, Merry and Pippin went to investigate the trophy room. As they did, Harry, Ron and Hermione went in one direction, while the four hobbits stayed to investigate the corridor. And they found Mairon's portrait. For a long time, the four hobbit lads couldn't take their eyes off the portrait. It seemed so mesmerizing.

"Well, we better go and help Harry, Ron and Hermione," Merry told them.

"Yeah," Pippin said.

"Come on, Pippin," Merry said. Pippin followed him a moment later, but Sam's gaze was fixed on Frodo.

"What is it Mr. Frodo?" Sam asked.

"Yeah." Frodo could help staring at the frame.

Then he found it: the date that meant Mairon had been present at Hogwarts fifty years ago. Maybe they were onto something. At a tug on his sleeve, Frodo moved away from the portrait. When his vision returned to the present state, it almost felt like he had woken up from a trance. He wondered how much harder it was for everyone else who gazed at the portrait. Then again, he wasn't sure himself how he managed to stop staring at the portrait. It seemed to be watching him as he made his way into the trophy room, where Harry, Ron and Hermione gathered around a trophy given to T.M. Riddle.

It was clear the truth was beginning to unravel right in front of their eyes.

o-o-o

The mood became much cheerier since there were no more attacks. Frodo could only assume the attacks had finally ceased and there would be peace in the air. The authors and authoresses were also allowed to see the hobbits, witches and wizards more frequently. However, when Frodo tried to speak to Aria, she was almost too tight-lipped to say anything about her own activity. He would have to fix this, maybe even add in an adventure.

"Aria, how do you feel about an adventure?" Frodo asked her one day.

"Ohhh!" Aria moaned.

"You don't want an adventure?" He asked, sadly.

"Nooo," she replied.

"Then what is it, Aria?" Frodo was very confused.

"Ah. Excuse me, Frodo. Please!" Aria darted down the corridor in a frantic rush. Frodo did his best to keep up with her, but was plummeted to the floor by one of Lockhart's dwarf cupids. The hobbit boy glanced up in time to see Aria return to him, only to stand behind a suit of armor in embarrassment.

Oh no. Frodo had a bad feeling what this meant.

"I've got a message, a poem, to Frodo Baggins," the dwarf said, beginning his recitation:

Compassionate and brave, a stone he has faced,
Trials unending, with pranks and friends abound.
With eyes as blue as the sea, and a gallant retreat,
No other hobbit could have defeated
The Dark Lord of old.

Frodo waited until the dwarf moved to pick up the diary. However, when he did this, his gaze met Aria's. She was out of sorts and Frodo could tell. But he had to ask her: "Did you write that poem?"

Aria nodded silently. Frodo was at a loss for words until their eyes met the diary. When he looked up again, she had vanished. He met her gaze one last time, before she turned the corner. Frodo wanted to follow her, but figured it was better to let her go. Whatever was on her mind… well, it would be revealed soon enough, wouldn't it? She couldn't avoid him for too much longer.

*.*.*

Frodo stayed in the Ravenclaw common room until after everyone went to bed. Glad to have the privacy, he took another good look at the diary. It certainly looked ordinary, and yet he felt an invisible tug at him, as if the diary had feelings. Opening his ink bottle, Frodo turned to the first page. He dipped his quill into the ink bottle and let a drop blot the page.

The ink sucked itself into the page, vanishing from view.

No way, Frodo thought in awe. Dipping the quill again into the ink bottle, he scrawled on the page, "My name is Frodo Baggins."

The words vanished. Only new words came up in a handwriting not his own.

"Hullo Frodo Baggins. My name is Mairon. How did you find this diary?" The words vanished a moment later.

Frodo answered with a written reply, "I found it in a bathroom. Someone tried to flush it."

"You needn't worry. This diary holds memories most dear to me, memories you have yet to learn." The words vanished and new words appeared. "You see I came to life at the time when Hogwarts was most in need of my assistance. I helped the Prefect uncover the Chamber of Secrets and know who is responsible for the attack. I can show you, if you like."

"I'm at Hogwarts now." Frodo dared to write next, "Show me."

"Very well. I shall take you back fifty years ago, where it all began."

The pages blew on their own, coming to a page that said June thirteenth. Frodo moved the diary up to his face, as he was sucked into the brilliant flash of light. He felt his body was sucked into the diary until he landed just outside Professor Dumbledore's office.

"No way," Frodo said, surprised. Before he reached the door, two figures stood before him. One was a fifth year boy, donned in Slytherin robes, and a tall angelic, elven figure, also wearing a Slytherin uniform. The elven figure, given his appearance, must have been in the same year as the teenage boy.

"Come in," an elderly figure spoke from somewhere in the other room.

Frodo waved his hand at the two figures. Neither of them saw him. He tried again, speaking to them. "Hullo. Hullo!" Nothing he did helped. Then he remembered: he was in the diary. He would be a wight to them. It was the only conclusion that made sense in this situation.

Quickly and quietly, Frodo followed the two into Dumbledore's office. Only when they entered the room, Frodo was stunned to see Harry present in the same room as he. Upon approaching Harry, Frodo did his best to speak to him. "Harry, you're here too." Harry didn't respond, his attention fixed on the Slytherin boys. "It's me. Frodo Baggins. Harry?" Frodo waved his hand in front of Harry. He couldn't see him, and yet he looked like a ghost.

What did this mean?

As Frodo listened to Professor Dippet – who Frodo just learned from listening to the professor's conversation with Tom Marvolo Riddle – the hobbit lad turned his gaze to Mairon. Mairon was unusually silent, but then Frodo did feel a strange sensation of unwelcome emotions. The elven figure certainly left a trace of himself with the office.

Eventually, Riddle was set to leave the room. Frodo nearly followed Harry, but was stopped when Dippet spoke to Mairon:

"Was it really your intentions to come here tonight, Mairon?" Dippet added, "If you find out who the killer is, tell me."

"I will." Mairon nodded, "Good night, sir." He took off out of the office. Frodo followed at a gallant speed. At last, he and Mairon were down in the dungeons with Riddle and Harry, if only a moment too soon, for there was Hagrid, watching over a box. They were in the dungeons where Snape taught potions class to him and Harry. "Hullo Hagrid." Mairon certainly had a presence about him. Frodo was stunned. It couldn't be Hagrid.

Before too long, the spider inside the box was set loose. Frodo watched as Mairon and Riddle stood up against Hagrid. Before Frodo could do anything, he was pulled out of the dungeons, right back into the burst of light until he landed spread eagle on his bed.

The memory was now gone. Frodo was back in the boys' dormitory of Ravenclaw Tower. He moved Mairon's diary off of his stomach, just in time to see Folco enter the room.

"Frodo, are you all right?" Folco asked him, "You're looking at Mairon's diary. Merry and Pippin told me what happened and how you found the diary."

"Folco, it was Hagrid." Frodo repeated, clearer now, "It was Hagrid who opened the Chamber fifty years ago. I… I can't explain it. The diary showed me…"

"Tell Harry and Ron about it tomorrow." Folco moved to his bed. He admitted with care, "We'll figure this out tomorrow, Frodo. I know we will."

"I know we will." Frodo grinned to himself. Yes, they would. He hoped they would. And yet, his grin faded over what he saw. He couldn't believe Hagrid would do such a thing as open the Chamber of Secrets. There had to be more proof than this. He felt sure of it. But how? How would they prove this to be true or false? Hagrid was innocent, wasn't it? This memory Mairon showed him… he concluded on waiting until the next morning to figure this out, what he saw… everything.

Eventually, Frodo did get to sleep. But his mind was uneasy. Just who was Slytherin's heir? Why wasn't he getting enough information? These were questions that troubled him throughout the night. There was no way of knowing what would happen until he told Harry, Ron, Hermione and Sam the truth. And he would tell them. He just hoped they would understand where he was coming from with this new information…

Okay, so I'm caught up on rewrites. Thanks for reading. :) We'll see what happens next in the next chapter…
