By Reason of Insanity

A/N:I don't own Harry Potter or anything, that's all J.K. Rowling. I just own this silly plot. Enjoy!

Alright guys! I have gotten a lot of personal messages asking if I am continuing this story. DON'T WORRY! It is not being abandoned! So this story is actually doing a lot better than indicated by the amount of reviews I get. Very exciting to know! Now if I could only get more reviews Thanks for all the attention to this story guys!


"I see many familiar faces in my class today. I'm sure most of you remember me, but for those of you who do not; my name is Professor Remus Lupin. I will be your Defense Against the Dark Arts teacher again this year. Welcome!"

As Lupin finished making his introductions, his gaze immediately fell on Harry. As they made eye contact, he gave a quick wink and nod of acknowledgement before jumping into their first lesson.

"As most of you are aware, I have a condition known as lycanthropy. Can anyone tell me what this is?" Remus casually asked the class.

Like he predicted, harsh whispers and furtive glances spread across the room like wildfire. After a few moments, the palpable tension broke as Hermione slowly raised her hand.

"Miss Granger, if you would please…" Lupin nodded.

Hermione gave him a questioning look before easing into the subject, "A werewolf is a human being who turns into a near-wolf-like creature during the full moon. This affliction is the result of an infection called lycanthropy, usually occurring when a human is bitten by a transformed werewolf. A werewolf differs from an animagus in the fact that he or she does not choose to transform. With each full moon the person transforms and no longer remembers who he or she is. There is no known cure for the bite of a werewolf in his wolf-form. However, the Wolfsbane potion is the only known potion that can, in any way, make a werewolf less dangerous by allowing them to keep their human mind during transformation. But professor, we covered werewolves in third year."

"I am aware, Miss Granger." Remus answered before addressing the rest of the class. "I know all of this is just a refresher for you all, but I feel it is necessary for us to cover before we begin our actual lessons. Yes, I am a werewolf. But I do not want this to alarm any of you, which is why this topic will be our first lesson of the year. A get-to-know-your-professor experience, if you will, to address any concerns you may have."

Again, murmurs of fear and upset traveled across the room.

"Have you ever killed anyone?" A meek Hufflepuff asked from the front row.

Remus let out a short bark of laughter and smiled kindly to the girl. "No, I have never killed anyone."

The girl's very blunt question seemed to get the ball rolling for the rest of the class and soon questions were fired one after the other.

"Why did they let you come back?"

"Right now, Mr. McKinney, the Ministry of Magic, the Board of Governors, and thereby, your parents have much more to worry about concerning what goes on outside these walls. A competent, in-control werewolf that is highly recommended by professors Dumbledore, McGonagall, and many aurors of the ministry has become much less of a concern."

"Does it hurt?"

"It is a very painful transformation. I wouldn't wish it on my worst enemy." Lupin admitted sincerely.

"Professor, will you be taking the Wolfsbane potion Hermione mentioned?" Neville asked.

"Of course! Either professor Snape or professor Slughorn will be providing me with the potion every month. I am in more than capable hands."

"Are you staying here during the full moon?" A concerned Ravenclaw inquired.

Lupin took a moment to survey the room before giving them a firm answer. He moved from his position at the bottom of the stairs to walk around the classroom. "I will not be on Hogwarts grounds during the few days before, of, and after the full moon. I will be residing in my secure private residence during those days. Any more questions?"

"Professor Lupin, who will be covering our classes during those days?" Hermione asked, showing her approval for his lesson plan with a bright smile.

"Ah, the question of the hour!" Remus smirked. "While I am unable to teach your lessons, they will be covered by Professor Snape."

Immediately the class responded with groans and pained looks of exasperation.

"Now now, that is not a proper way to accept the news. Professor Snape deserves your respect." He admonished softly. "He will take over lessons the week of the full moon every month."

Harry and Ron exchanged horrified glances at the news. "Not the greasy git again! Blimey, he was bad enough in third year!" Ron mumbled.

"That's all we have time for today, I'm afraid. I would like a two foot paper on lycanthropy and the effects of Wolfsbane potion. It would also do well to include information on the social integration of werewolves into society. Good day!" Lupin concluded, dismissing the class.

Harry, Ron, and Hermione packed up their parchment and quills with the rest of the class as they listened quietly to the mixed chatter of their classmates. Malfoy's arrogant voice caught their attention as he spoke to a fellow Slytherin.

"I can't believe they're letting that filthy mutt teach! Didn't they learn their lesson the first time?" He crooned loudly.

Harry's knuckles whitened as they tightened around his bag in fury. He was not calmed by the weight of Hermione's hand on his forearm in warning. Ron seemed to reflect the rage burning in Harry's eyes with a face as red as his hair and a harsh snarl on his lips.

"At least he's not in prison, like your father!" Harry shouted, turning sharply to face the Slytherin.

"Don't you dare say a word about my father, Potter!" Malfoy spat as he rounded on the trio.

"How's Azkaban treating him?" he continued to taunt, pulling out his wand.

"Mister Malfoy, Mister Potter! Enough!" Remus seethed as he stood between them and forcefully lowered their arms. "Detention tonight for the both of you! Mister Malfoy, you will be with Professor Snape. I trust he will find a punishment suitable for you. You are dismissed."

Draco shot Harry a smug look of triumph before pushing past Ron and Hermione to exit the classroom.

"A moment, if you would, Harry? There is something I would like to discuss with you." Lupin said softly before ascending the staircase to his private office.

"I'll catch up with you guys later." Harry nodded, gesturing to them to go on without him before following his professor up the stairs.

"Please, have a seat and make yourself comfortable."

Harry looked around the scarcely decorated office as Remus took a seat in the wing backed chair behind his desk.

"Love what you've done with the place." He joked, finally sitting in one of the standard chairs across from his friend.

"Ahem, well, yes. I've already gotten a scolding from the lovely Miss Tonks. It seems my decorating skills are sorely lacking." Remus joked casually, attempting to lighten the situation.

"You wanted to talk, sir?" Harry asked, getting straight to the point.

"How are you holding up?"

A sharp stab of pain traveled through Harry's chest at the still sore topic of his godfather. "I'm doing about as well as can be expected, I suppose."

Remus nodded sadly and instantly felt for the young man in front of him. The boy had lost his last living family member. Just as Remus had lost the last of his dear friends. He was the last marauder.

"It was hard, sometimes, staying in his manor without him. And for a while I felt responsible. If I had just listened to Dumbledore and shut Voldemort out, Sirius would still be alive." Harry admitted quietly.

"You were trying to protect him, Harry. No one faults you for that." Lupin responded honestly. "But we are all concerned for you. Especially for your safety."

Harry looked up at the ragged man warily.

"It has come to our attention that you have had a…well a certain guest in your home. What on earth were you thinking?"

"I don't know what you're talking about." He hedged.

"Harry, I thought you trusted me enough to be honest with me. I know you have had Bellatrix Lestrange in your house. She was discovered there just yesterday. There is some speculation that you had her there willingly. Is that true?"

Harry sucked in a large breath of air between his teeth as he started to panic. The situation was getting out of control. He knew. They knew. The Order knew. Bellatrix was going to kill him. He was never going to see her again.

"Harry, calm down!" Remus implored, breaking him out of his panic attack. "I do not want you to think I am attacking you. I just want to understand."

"Remus, I can't tell you anything. I know what I am doing. She wasn't hurting me, she was teaching me. I was perfectly safe."

"Perfectly safe? Harry, this is Bellatrix Lestrange we are talking about! She's murdered hundreds of people. She killed Sirius!"

"That's just it, Remus! You don't understand. I have foolproof evidence that she is innocent." Harry argued.

"She is a Death Eater…A master at manipulating people. She is playing you for a fool Harry Potter!"

At this Harry narrowed his eyes dangerously. In a low, vicious whisper he replied, "I won't let you turn her in."

Remus visibly deflated. "Alright. I don't want to alienate you. I'm just trying to protect you."

"Then trust me." Harry begged. "Trust me enough to let this pan out. And when the time comes, take my side. Have an open mind to the evidence and let it speak for itself."

Lupin searched Harry's face desperately for any sign of interference and found none. With lasting hesitation, he nodded his head in defeat and acquiescence. A pit of worry for the boy settled deep in his gut and he prayed to Merlin that Harry knew what he was getting himself into. He could never live with himself if he failed his best friend by leading his son to his death.

Harry easily identified his mentor's reluctance and beamed in encouragement. He had, for the moment, found another ally. He just hoped he could keep Bellatrix hidden long enough to defend her adequately when the time came. He could not…would not continue this journey without her. If the wizarding world wanted their 'chosen one' then he would need her by his side.
