Jack Frost headed to the Hospital Wing a Cheshire Cat worthy grin appearing on his face as he entered and saw Hermione was now half cat herself.

"Made a mistake then did you?" he asked coming over "I told you not to use it, but would you listen?"

Tears welled up in Hermione's eyes as she grabbed her pillow and covered her fur covered face.

"Jack, no offence but I don't think you're helping," Harry said as Madam Pomfery came over to see what was wrong.

"What? It's her fault for not checking the hair she used was actually from the student she thought she pulled it from," Jack began in a whisper as the nurse was still there "And I'm sure the book would have said how to define if it was safe to have by the colour and the smell it took when it was added. This is why I suggested asking Peeves to help us instead, it was less dangerous." he finished nodding to himself. And he got the answer two weeks ago."

Feeling it was the boys that was upsetting her patient, Madam Pomfery sent them away.

They did and as they were heading towards Gryffindor Tower Jack asked how much of the potion did Hermione drink?

"About half a beaker full," Ron said "We all did, but Harry and I changed back when the hour was over."

"That's because you added and changed into humans," Jack said thinking "Going by the amount, and how hairy she was, I'd say it will be at least a couple of weeks before she's back to normal."

When the holidays were over, students were coming to the Hospital to see what was wrong thinking she had been attacked too.

It got so bad that Madam Pomfery got out her changing curtains and placed them around the bed to save her from being seen and mocked for her fury face.

When school started again Harry and Ron were visiting her every night with each day's homework.

Jack only visited occasionally with mixed reasons of 'This was your own fault so you should deal with this yourselves.' and 'Madam Pomfery doesn't like me here because I make too much noise and disturb the other patients.'

At dinner one day a couple of weeks into January, Ron was telling Jack about the 'Get well card' Lockhart seemed to have given Hermione.

"And she sleeps with it under her pillow!" Ron finished in disgust before he took a bite out his steak pie.

"Well where else would she sleep with it?" Jack asked but agreeing with Ron that he could not believe her.

"In the bin?" Ron asked his mouth full and spraying a bit of pie across the table at Harry "Opps sorry Harry."

"Don't worry Ron; I'm sort of used to it because of Dudley." Harry said taking his glasses off and cleaning them.

Jack was about to ask about this when Ron started complaining (once again) about how much of a twit Lockheart was.

"I mean it wasn't a get well card it was an autograph for Morgana's sake!" he said slamming his fist holding his fork onto the table.

"Oh ho what's this?" Fred's voice said as the twins came over "Is our little baby brother having another tantrum about Lockhart?"

"It certainly seems so," George said leaning forwards and inspecting him like a doctor would. "Now what could have been the reason for it this time?"

"They went to see Hermione and saw she got well card from him," Jack said getting to the point.

"Now Ron, if you're jealous of him getting her a card, then get her one yourself…" Fred said tutting and shaking his head.

Ron just ignored them and mumbled to himself as he carried on eating.

"So what brings you guys over here?" Jack asked taking out a thick lickerish wand, placing it between is first two fingers on his right hand, leaning back and started, sucking on it. A smirk crossing his face betting every gangster boss – real and spiritual, would be so proud of him.

"Well, Mr Frost…" Fred said smirking too "We need your help."

"And what sort of 'help' do you need?" Jack asked not caring that everyone around them was starting to stare.

"We believe a certain someone," George said looking to Ron then the top table to where Lockhart was sitting "Has plans to ruin one of your friends birthdays next month."

Everyone was confused about this but Jack seemed to understand as a look of shock seemed to cross his face before he got his poker face back.

"I see. And what exactly do you expect me to do about it?" he asked. "Expect him to do about it?"

"Something to make it not be ruined," the twins said together before coughing and adding "Mr Frost."

"I'll see what I can do," Jack said waving his hand to signal that they could go now.

Nodding the Twins went off to join Lee Jordon and everyone else was broken from the spell seeming place upon them.

"What the bloody hell was that all about?" Ron asked confused as Jack finished the wand and got back to his dinner.

"Nothing for you to be worried about yet Ron," Jack said imaging the look on Cupid's face and the words he would say when he tells him this "Nothing to be worried about yet."

After dinner Harry, Ron, and Jack were heading up the stairs together to go to bed when they heard Filch complaining about something.

'…even more work for me! Mopping all night, like I haven't got enough to do! No, this is the last straw, I'm going to Dumbledore…'

"What are the chances he's just practising some poetry?" Jack asked too tired to get to do any poking around tonight.

"Not that high," Harry said "Come on…"

The three of them rounded the corner and saw a large puddle of water coming out from Moaning Myrtle's bathroom and could her hear crying from inside it.

"Oh now what's wrong with her?" Ron asked getting a big hard punch and a dark look from Jack.

"Ow! What was that for?" he asked rubbing his arm.

"She is crying Ronald!" he said "A girl, a girl who was still a student here when she died and became a ghost, is crying! You don't ask that sort of question about someone like that! She's still an infant in ghost-years she's probably crying because something went through her and she wasn't expecting it."

"Well only one way to find out," Harry said breaking up the fight before Jack could hurt Ron anymore.

They went inside and saw all the candles were out, and the walls were wet.

They went over to the cubical Myrtle was in the first time they saw her and knocked gently before open it.

"Who's that?" she asked sniffing "Come to throw something else at me?"

"Why would we throw something at you?" Harry asked while Jack was giving Ron a glare.

"Don't ask me," she said coming closer "Here I am, minding my own business, and someone thinks it's funny to throw a book at me…"

"But it can't hurt you if someone throws something at you right?" Ron asked "I mean, it will go right through you, wouldn't it?"

Before Myrtle could start crying/screaming some more, Jack had grabbed Ron and pinned him to the ground.

"Oh sure what a fun game for Ghosts and Spirits, Ronald," he said teeth grinding "Let's see is you like it huh? Ten points to me if my fist goes through your stomach!" he said punching Ron in the stomach very hard, knocking the wind out of him "Fifty points to me if I can get my fist though your head!" he said this time aiming for Ron's face but missing because Ron quickly rolled away meaning Jack hit the floor instead.

Before he could do anything else Harry pulled him off Ron and helped the idiot up.

"Who threw it at you Myrtle?" Harry asked trying to change the subject.

"I don't know," she said liking Jack a little more now he stuck up for her like that "I didn't see them. I was just sitting in the u-bend thinking about death, and it fell though the top of my head. It's over there, it got washed out." she pointed over to the sinks.

Still mad at Ron, Jack went over to look at it.

It seemed to be a rather old looking book possibly a diary by the plain cover.

Harry was about to pick it up for a better check when Ron grabbed his arm and stopped him.

"Are you mad, it could be dangerous," he said in a whisper.

"Dangerous?" Harry asked a hint of a laugh in his voice. "Come on, how can it be dangerous?"

"You'd be surprised," Ron said staring at the book "There are some books the Ministry confiscated – Dad told me – there was one that burnt your eyes out. And everyone who read Sonnets of a Sorcerer spoke in limericks for the rest of their lives."

"Yeah and I heard there are some that people just cannot stop reading," Jack said getting out his wand and pointing it at the diary to do a hover charm on it "Everyone just had to do everything one handed and never get any sleep."

Ron nodded to say that this was true.

"All right I get the point," Harry said pulling his hand back.

Nodding Jack said "Wingardium Leviosa" and floated the book over to them, opening it magically and turning it over to see the back.

The faded year told them it was fifty years old and the name on the first page said 'T. M. Riddle'.

"That name's familiar," Jack said thinking "I think I saw it on one of the 'Special Services to the School' plates in the trophy room when I did that detention with Filch"

Going through the pages one at a time they saw it was blank.

"He never wrote in it," Harry said a bit disappointed.

"I wonder why someone wanted to flush it away?" said Ron curious.

Jack turned it so the back was facing them again.

There was a printed name of a newsagent's in Vauxhall Road, London.

"He must have been Muggle-born," Harry said "To get a diary from Vauxhall Road."

"Or he was just raised by Muggle like someone else we know," Jack said looking at Harry with an 'I can't believe you' look."

"Well it's not much used to us," Ron said about to say something else, but stopped himself as he saw the glare Jack was giving him.

Pulling out a plastic sandwich bag from his pocket, Jack placed the diary inside it, feeling that there was indeed something wrong with this book.

"I think we should tell the teachers about this," he said as they left saying goodbye to Myrtle "And not touch it with our bare hands or write in it. Until we know what's going on."

A little disappointed with those 'rules' Harry and Ron nodded.

"Seeing how late it is, I think we should see the teachers tomorrow." Jack continued when they got to the Common Room "For know it can stay in my trunk."

That night while everyone else was asleep, Jack wrote a letter to Cupid asking him to meet with him within the next few days, and sent it off with Archimedes.
