Harry was up in his room, wondering what this detention will be like. Hopefully, nothing like he had to endure in the muggle world. The thing that he did like about the detentions; is he is away from the Dursley's for a little while longer.

Knowing that Snape is not really the nicest guy, in fact he can be cruel to Harry, but it is an act. Harry can sense that. 'Why does he pretend to hate me?' must be a good reason behind that. Maybe tonight he will be able to find out. He looks over at the clock, knowing that dinner will be in thirty minutes he gets up to get ready.

Sitting down at the dinner table, Harry looked over at the staff table. Snape nodded at him before talking to Quill. George and Fred got a great prank idea. "Our teacher will be a great subject to this prank," they held out a bottle to show them. Ron had his mouth full of chicken while checking out their new creation, "It is called, a Willy Gilly Drop. One drink from this and he can spill his deepest, darkest secrets."

Harry gapped at that, thinking how cool that will be, "And how do you suppose we give it him?"

The twins looked at each other, then at Harry, "Leave that part to us."

Harry thought about how the twins were going to administrate the drops; without getting caught. Commotion was suddenly going on in the dungeon. Realizing it was Flitch's voice, "Show me?" Harry heard from outside Snape's office, "show the whole world who you are?" the Professor seems to be struggling, "I said show me!" the Golden Boy, peeked his head inside, realizing that Filch is forcing Severus to show his mark and the Potion Master was trying to push him back. Harry got out his wand, readying himself. "Hey!" he shouts, closing the office door, so no one else sees this, "step away from our professor!" he moved closer to Snape, pushing Flitch away from him, "leave his office, now!" he points the wand at his face.

"You dare harm a staff member?" Harry realizes this and lowers his wands, "this matter is strictly between me and Severus."

Snape was clutching his arm. "Forcing another staff is harming a staff member too. Is it not?" Filch had enough of this and left the office. He could hear his professor huffing behind him. Harry turned around, "he probably realized his error there." Severus nodded, keeping a hold of his arm, "Flitch wanted to see, didn't he?" Harry guided him over to a sofa, that was in his office; getting him to sit down.

"Why would you-"

Knowing what his teacher wanted to ask, he answered, "Because you were struggling that's why. He wanted to see, but you have the right to your privacy; Professor," Snape nodded, agreeing with that, "no matter the circumstance," getting permission to roll up the sleeve, Harry looks over at the mark, "Did it hurt Professor?" he wondered, "when it was placed on you."

Snape looks over at him, "More than words can express," he says through gritted teeth. His student felt bad for him. The dark teacher cleared his throat, "Well, you have detention with me still," he stood up, heading over to the desk. Harry wondered what his teacher had in store for him. Snape told Harry to wait here as he disappeared out of the room.

Few minutes have past, and Snape reentered the office, holding a coat. It was the same one he was wearing during the quidditch match. Putting draping in over his desk, getting a medium sized book from his drawer he walked over to Harry, handing it to him, "Your first job is finding out how to remove the damage you caused on this winter coat."

Potter gapped at that, "But sir I wasn't-" he thought better then telling him it was his friend, "no problem, I will get started on it," he takes the book and goes over to the desk. Looking at the coat, he noticed a medium sized hole burnt into the fabric. He looks over at Snape, "I am sorry about this."

"You should be," he walks over to the sofa, "what are you waiting for? Get started," he snaps, "you find the magic spell to remove it inside that book. Now get to it."

While Harry searches through the pages, the Potion Master looks over the papers he needs to grade. The Boy-Who-Lived looked over at Snape ones in awhile to see if any of his papers are getting graded yet, 'Hopefully he gives me a good grade?' Going back to searching. Examining the burnt of the coat, feeling bad that Hermione ruined perfectly good material. Although she was just doing it because we thought he was against them.

Harry found the page he was looking for, getting out his wand, standing up to have a better angle. Pointing the stick at the coat and spelling out the words. Snape looks at his work, getting up to check. The burnt part was gone. The Golden Boy was pleased with his work, handing it to his professor, who took it, bringing it back to his chambers. Impressed that Harry found the spell in under 10 minutes.

Potter waited for his next assignment, looking around the desk, knowing well not to check the drawers. Snooping will not go well if he gets caught. Going over to the bookshelf, to snoop there. Not seeing a problem with it. Looking over at the titles. They were in alphabetical order, 'So orderly,' he thought, 'in the muggle world he would do well in Libraries or bookstores.'

"What are looking at?" he heard Snape behind him, seeing why Harry is interested in his book collection.

"I am just curious on what you got Professor," a lot were falling apart if you even try to touch them. A few having dust, "Professor if it is ok with you, can I clean some of these?" he looked over at him. Severus did not expect him to ask him to clean books, "at home I am not allowed to pick up a book or go to the library."

Snape had the same thing happened to him as a child. Looking over at his books, "I suppose you can do that," he peers over at the clock, only a half an hour to go. "Careful on some, they can be fragile," he went back to grading his papers. Harry was happy to help with this. "If you promise to bring them back, I wouldn't mind you burrowing them."

Harry was shocked at that, 'Could I really borrow these?' this made him smile while taking them out to dust them. Planning to bring a few back with him.
