Disclaimer I do not own Harry Potter.

Dolores Umbridge was under the firm belief with Dumbledore and Weasley twins gone, she now had complete control over Hogwarts.

She couldn't have been more wrong; somewhere in that castle, one student was planning Umbridge's downfall and was going to use the students who had crossed them over the years to do so.

The first student chosen was Seamus Finnigan.

Seamus had received a letter from
an unknown owl.

Seamus opened the letter curious of the contents within; his scanned the page taking all the words in.

Dear Seamus,

Your probably wondering why you
have received a letter from an unknown owl. The truth is, I wish
to remain unknown.

Our school is under the control of a power-hungry cow and it is my wish to make regret her ever stepping foot in Hogwarts.

I bet you are now wondering why I'm telling you this - you are going to help me meet my goal.

Tomorrow in D.A.D.A you will constantly interrupt Umbridge.

How you do it I do not care, but you will do it or I'll be informing Professor Snape that you have broken into his potions supply cupboard for ingredients to give to a Ravenclaw girl that you wanted to impress.

Sincerely,
Bitter Revenge.

Seamus had two choices: ignore the letter and hope that they wouldn't tell Snape or do what the letter said and end up in one of the toad's detentions.

Seamus knew that if the writer of the letter did tell Snape, he'd be in even more trouble and would end up in detention either with Snape, or Umbridge if she insisted upon being the one to over-see it.

Seamus came to the conclusion that it'd be better to just to do what the letter sender wanted and hope that he didn't get to many detentions.

Seamus set of to Defense Against the Dark Arts with a heavy heart and butterflies in his stomach.

He felt as if were being watched, but by who he did not know; it had bugged him why he had been chosen to do this.

Seamus sat at front the of the class and waited for the others to sit and for Umbridge to begin.

"Now, who can tell me what the
proper response is to a werewolf attack?" Umbridge asked.

Seamus raised his hand so he could begin what the writer of letter had asked... well, blackmailed him to do.

"Yes Mister Finnigan," Umbridge
said.

"Scream for your mummy and hope she can hear you," Seamus said,earning laughs from the other
students.

"No, the proper response is to
send word to the Ministry," Umbridge said, completely ignoring that it was obviously a joke answer.

"Um, I'm pretty sure my answer is
correct," Seamus said.

"Mister Finnigan, unless you would
like to spend this evening in detention, I'd be quiet," Umbridge warned.

"Just admit it, you want to get me alone, professor," Seamus said, making his voice sound as dramatic as possible.

"I do not want to do any such thing," Umbridge told him, her voice sounding a bit strangled.

"Alright, don't get hysterical. Jeez,"
Seamus told her.

"Mister Finnigan, meet me in detention this evening," Umbridge said.

"See, I said you wanted to get me alone!" Seamus cried.

"Mister Finnigan, I do not want to get you alone, let me assure you. Also, there is going to be at least six other students also in detention, now let me get on with my lesson," Umbridge informed him as the students looked at
Seamus to see what else he'd say.

Seamus said nothing and let Umbridge get back to teaching for five minutes before he interrupted her again.

"Professor, if Zombies attacked, what should we do?" Seamus asked.

"Mister Finnigan, there is never going to be a Zombie attack," Umbridge said glaring at him.

"But He-Who-Must-Not-Be-Named
said there would be," Seamus said,
knowing that mentioning Voldemort would bug the crap out of her.

"Mister Finnigan, HE-WHO-MUST-NOT-BE-NAMED did not you tell
you that because he is dead. Report to your head of house this instance!" Umbridge shrieked.

"Fine, I'm going," Seamus said.

As Seamus walked to Professor McGonagall's classroom he couldn't
help but wonder if he'd be hearing from Bitter Revenge again.
