Note: Those that are shocked are those that taught Severus when he was in school and Lucius Malfoy. I'm having Professor Sprout pick Harry up as there's no info that she taught Severus at all. She'll be one of the few Professors that won't know any similarities between Harry and Severus. Harry will be placed in Ravenclaw because he's really, really, smart.

Chapter 1: Harry Meets Professor Sprout

Dumbledore's POV

"This year Harry Potter is coming to Hogwarts," Dumbledore told the staff, "Now I would send Hagrid to fetch the boy but I believe that Professor Sprout should have that honor."

"Why thank you, Albus," Professor Sprout said, looking pleased with herself.

"Great I have to put up with Potter all term," Professor Snape, Potions Master and Head of Slytherin House, commented.

"Well you'll only be seeing him during your stupid potion lesson," Professor McGonagall told him, "I know that he'll end up in Gryffindor."

Professor McGonagall was the Transfiguration Mistress and Head of Gryffindor House.

"That's nice," Snape said.

"Severus, try and be nice to Harry," Dumbledore asked of him.

Snape glared at him but said nothing.

When the meeting was over Dumbledore left Sprout to get going and collect the child. He knew that the Dursley's would most likely not take him to get his things which was why he had delayed the child's letter. He just hoped that Harry didn't act like his father. He really didn't need to hear a full year of whatever the child had gotten up to reminding his Potions Master how much Harry was like his father.

Harry's POV

Harry Potter had just finished cleaning the attic when the doorbell rang. The Dursley's were home, of course, and he knew that they would answer the door. Harry was a slightly tall child with black hair, a slight hook nose, and brilliant green eyes. He was glad that he didn't wear glasses as his cousin most likely would have broken them. When the doorbell rang again Harry sighed and went downstairs to see who it was. When he opened the door he found himself facing a woman that he had never seen before.

"Hello, I'm Professor Sprout," she said, "Are you Harry Potter?"

"Yes," Harry answered.

"Great, I've been sent by your new school to make sure that you collect your supplies," she told him, "Is your relations home?"

Harry nodded and then Sprout asked, "May I talk with them?"

"Sure," Harry said and he let her in.

No sooner had the door closed but his Uncle Vernon came in and he wasn't happy. Harry saw his Uncle's face go white and then his Uncle asked, in a rather rude tone, "What the hell are you doing here, you freak?"

"Excuse me," Sprout asked.

"Oh don't give me that," Uncle Vernon said, "I know that your kind understand English. What are you doing here, freak."

"I'm not a freak and I'm here to collect Harry," Sprout told him.

"Will he be coming back," Uncle Vernon asked.

"If you want he could stay at the Leaky Cauldron until September and he wouldn't be coming back until next year."

"Fine," Uncle Vernon said and he slammed some pounds into Harry's hand, "Use that only for the room and it better be enough."

Harry was shocked that his Uncle had given him money.

"Go and don't come back until next year," Uncle Vernon said and Harry knew that it was his cue to leave.

Professor Sprout took them to London on the train. Harry had never been to London and he could tell that she was upset about how Uncle Vernon had treated her. He was use to it, along with the beating and the starvation. When they finally arrived she took him to 'The Leaky Cauldron.'

Once inside a man named Tom took them to Diagon Alley where Harry could get his money changed and get the money from his vault. Harry, personally, didn't know that he had money but Professor Sprout told him that his parents had left it to him. Naturally Harry asked her if she knew her parents.

"Sorry, didn't teach them," she said.

"What exactly do you teach, ma'am," Harry asked.

"Herbology," Professor Sprout answered.

The trip to Gringotts wasn't as hard as Harry thought it would be. Naturally he was shocked at how much money that he had but Professor Sprout waved it away and helped him put some money into a bag. Once done she took him back to the land of light. The first place that they went was Madam Malkin Robes for All Occasions. While the witch fitted him he saw her putting things on the counter. Once done he joined her and she paid for everything.

The next shop was all about ink, quill, and parchment. While he was looking for the ones that he wanted Sprout told him that she was going to send off his reply back to the school so that they knew that she had him.

"I'll wait here until you come back," Harry told her.

"I won't be long," she said and then left.

Professor Sprout ended up being gone for ten minutes and while he waited he looked around at all the different quills. He found one that said Self-Correction Quills.

"Oh you don't want one of those," the manager told Harry.

"Why not," Harry asked.

"Their only for those that cheat," he answered, "And that includes people not like me."

When Professor Sprout returned she paid for everything and then they headed for the next shop.

The rest of the trip wasn't filled with creepy managers that thought that maybe Harry was going to cheat in school. The bookshop really held Harry's interest. There were books there that Harry had never seen and Harry wanted to get everything. Professor Sprout let him have a couple of extra books and Harry at once picked out a couple of Potion and Charms text.

"Trying to make a good first impression," Sprout asked him.

"I just want to prove that I belong," Harry told her, grinning.

Sprout grinned back.

The Apothecary was interesting to Harry too. He at once started to explore all the ingredients that they had while he heard Professor Sprout asking the manager for some basic potion ingredients. Harry wanted to get extra but Sprout told him that he would have to wait until he was more advance before he got any of the good stuff. Harry wanted to pout but the last time he had done that his Aunt had slapped him. Once they had left she took him to get the last bit of his supplies.

Dumbledore's POV

"I wonder what the child is going to be like," McGonagall asked, "I bet he'll be just like his father, brave and an excellent Quidditch player."

Dumbledore had been wondering about that as well. He had vowed not to check on the child not because he didn't care of him but because he didn't want anything to happen to cause anymore problems. He also worried that Severus would take out his grudge on the small child. Harry didn't need anymore bullies in his life.

"Albus," McGonagall suddenly said.

"Yes," Dumbledore said.

"Do you think he'll be like Lily, really smart," McGonagall asked.

"I don't know, maybe a little of both," Dumbledore answered.

"I hope so," McGonagall answered, "It would be nice to have a smart child here again. Lily was such a pleasure to work with."

"I know," Dumbledore said.

Later on Sprout returned and told him that Harry had gotten his things. Dumbledore didn't ask which shops that Harry liked because it would most likely be answered "the broom store." She did mention how horrible the boy's Uncle had been.

"He just slammed money into poor Harry's hand," she said.

"Is he back with his relations," Dumbledore asked her.

"No, he's staying in the Leaky Cauldron," she answered, "I'm afraid that his Uncle wouldn't let him back until term ends."

"Thanks for telling me," Dumbledore said and Sprout left. "Sometimes, Tuney, I wonder what's wrong with that brain of yours."
