Disclaimer: I don't own Harry Potter. I wish I did.
Harry returned to the hidden potions lab. It took him several minutes to find the Syrup of poppies he needed for potions class on Monday. He took only the one phial leaving the others. As it's a class 2 controlled substance he couldn't get it by owl order. Snape had handed them a permission slip for one sealed single use phial Friday to present to the apothecary in Hogsmeade in order to be able to acquire it.
"Potter, what are you doing in here?" Snape said a hint of anger coloring his voice.
Harry turned to face Snape. Snape was not wearing his teaching robes though he had a robe on the looked much like a lab coat down to the white color."I forgot to get a phial of Syrup of Poppies when I went to Hogsmeade yesterday." Harry replied.
"So you are the one Madam Vane told me of. I give out only a set number of those permission slips Madame Vane knows that number. Only her apothecary is allowed to supply underage students the phials of Syrup of poppies. Some one not turning in one to Madam Vane, she informs me of it. This lab is set up for Madam Pomfrey's use do not in the future remove ingredients from it. For your detention you will report to her for one week at 7 in the evening. In the future remember to acquire the needed ingredients yourself. Return the phial to the shelf. Bring 5 sickles to class with you in the morning. You will be able to purchase the phial then." Snape said coldly. He waited until Harry had complied and had left the lab.
Harry brought the 5 sickles he needed to class in the morning. Snape gave him the single use phial then told the class that if they forget to acquire restricted ingredients he will have a small stock on hand for purchase in the future? He then swept through the room checking the seals on the phials. Satisfied he let them start the first phase of the potion. About 20 minutes before the end of class Snape had them stop and clean up. Each potion was transferred to ironstone crocks for a week of aging.
"Mr. Potter stay after class." Snape ordered. Once every one was out of the room. "Potter tell me what you see?" Snape indicated a cage with three mice like creatures in it only instead of fur the mice like creatures where covered in scales of a dusty dark blue.
"Not sure what they are but there are three mice like animals in the cage." Harry replied puzzled. "They have scales instead of fur and are a dark blue in color."
"You may go. Mr. Potter." Snape dismissed him.
Ron and Hermione had waited outside for him. "Prof. Snape wanted me to tell him what was in the cage by his desk." Harry explained to his friends.
"The cage was empty," Hermione said. "That doesn't make any sense."
"Harry was there a mouse sized animal with dark blue scales?" Ron asked.
"Yeah, three of them." Harry replied puzzled.
"Do the enchanted items in the common room glow?" Ron asked.
"Yeah, so?" Harry commented a touch puzzled over what had Ron so excited.
"Wicked your Magic Sight is coming in early." Ron grinned. "Are you seeing colors yet or is it just a glow still?"
"A little bit what does it mean?" Harry asked.
"Enchanted items give off a light to some one with mage sight. Bill says the colors can tell you what types of spells where used to enchant the item." Ron explained. "It usually manifests when a wizard is in his mid twenties. Only about 1 in 4 wizards have it."
"What does it mean when it manifests early then?" Hermione asked.
"I don't know." Ron shrugged.
By that time they had arrived at their next class. That evening when Harry arrived for his detention with Madam Pomfrey she set him to cleaning out a storage room. While he was doing that 2 7th year Slytherins came in with them was a Hufflepuff girl who had clearly been badly hexed.
"Miss Brown what happened?" Madam Pomfrey asked indicating a bed for the poor girl.
"We think Samuel Brown did this. We found her by the path to the stables." Miss Brown said.
"I see. Mr. Potter come here." Madam Pomfrey ordered. "Tell me what you see." She ordered while lowering the lights enough to let the his mage sight see the faint glow.
Harry studied the girl then began to describe what he saw. Madam Pomfrey listened then asked questions of him. The two Slytherins waiting in the background. When he was finished Madam Pomfrey raised the lights. Beginning her diagnostic spells. Harry went back to cleaning out the storage area. When he finished he was met by the two Slytherins outside of the infirmary.
"I'm Sarah Graham, both of my Parents are muggle born."
"Andrea Brown, my Dad's a muggle."
"What do you want?" Harry asked nervously.
"Just to tell you that you do have allies in Slytherin and to watch out for Samuel Brown. He likes to hex students younger then him. Specially those with unusual magical talents and less then Pure Blood. That girl has beast tongue with an affinity for cats and her parents are muggleborn. Don't let him know you have mage sight." Andrea said. "He's a so called Pureblood with no special magical talents and he hates every one with any special talents. It doesn't help that his family is half squibs."
"Is Brown in Slytherin?" Harry asked.
"Ravenclaw 5th year." Sarah answered.
"Thanks for the heads up." Harry said and went back to his dorm. The next evening Madam Pomfrey had him sit down and identify magical objects using his mage sight. Sorting them into groups according to what colors they glowed. It was during this that he had an episode of pain. It was as brief as usual lasting only 2 minutes. This time the pain encompassed both his arms, his head and mid way down his chest. Madam Pomfrey cast a diagnostic spell over him.
"As I thought magical growing pains, Mr. Potter. As your body grows so does your magic. When you have a growth spurt your channels of magic also grow. If the pain lasts longer then 5 minutes come to me immediately it's a sign that something is wrong." She told him. "Now is your mage sight stronger?"
"I can see more colors." Harry admits. "They're brighter too."
"Good. I'm going to make you an appointment with a healer who specializes in eyes. Your glasses prescription will need be changed to allow for mage sight. From now on you will have to get your glasses from the magical world and not a muggle eye doctor. I'll inform your relatives of the requirements and that the glasses are covered by the magical version of the National Health." Madam Pomfrey told him.
When he left the infirmary he stopped to try the door to Madam Pomfrey's potion lab. It was locked against him. Over the course of the next several days he tested the secret doors and passage ways he found. About a third of them where now locked against him. Most of them where empty rooms and not the passageways. He did note that the locked doors where in corridors where the rooms where the only spot to hide was the secret room.
