Whew long list okay on with the story

"So who'd you tell to come " Ron asked Hermoine and Peter as they entered Hogshead

"Whoever was interested" Peter said,"A lot of people are interested you know "

The door opened and Susan and Edmund came in followed by the twins and more and more people trickled in.

Hermoine stood up,"Well,we're all here for one reason ,and that's to learn how to properly defend ourselves and since Harry is the best person to teach us we're going to learn from him."

"Is it true" Dean asked "is You-Know-Who really back"

"Is it true you saw him kill Cedric " someone else asked

"Yes and yes" Harry said getting angry,"Look if you all just came here to hear me talk about Cedric's death you can clear out,and if you all think I'm batty ,you can clear out for that too"

"No one does" Susan said softly ,she looked at him"We need to learn this stuff"

The others nodded and Hermoine beamed "So all in favour raise your hands",everyones hand went up.

"Good" Hermione said a look of satisfaction on her face. as everyone signed their name on a piece of parchment.

"That went good,didn't it" Hermoine said as they headed back to Hogwarts.

The next morning Edmund came to the table looking a bit upset,behind him was Lucy and she looked angry

"I don't know how,but Lu found out" Edmund said sitting down

"I want to join" Lucy said

"I told her I'd ask you" Edmund said reaching for the platter of bacon

"Lu,how'd you find out" Peter asked

"I won't tell Umbridge if that's what you're worried about "Lucy said settling herself next to Ginny

"I guess you can join,but not one word to Umbridge" Peter said swinging his satchel over his shoulder.

"So how did you find out" Edmund asked as Hermoine,Ron,Peter and Harry left.

Lucy swallowed a bite of eggs ,before replying "I oveheard Michael and Su whispering about it in the halls,no one else was around" she said.

"Anyone want to buy some Puking Pastilles or Fainting Fancies" Fred asked "We have 500 galleaons already.

"People actually bought them"Lucy asked wrinkling her little nose

"Why wouldn't they,they get you out of class" George said,ruffling Lucy's hair,Lucy stuck her tongue out and went back to her breakfast.

Before they could have their first meeting ,they needed a room to practise in,luckily for them Malfoy and his gang was being especially cruel to Lucy,because that was the day she found the Room of Requirement and hid there all day until she felt it was safe to come out.

Lucy clambered through the portrait hole and into the common room,she was wriggling with excitement,"I found a room!" she cried "I was running from Malfoy and his friends and this room appeared .It had everything I needed too"

"Wow,Lu you found the Room of Requirement" Hermoine smiled at the younger girl

"That's good,we could use that for practising"Harry said glad they had a room in which to practise .

Next chapter Umbridge becomes High Inquisitor and forms The Idiot Squad
