A/N- So it's been a few years since I updated this story and I am very sorry to those who started to follow in the beginning.
Chapter 3-Revenge is Sweet
The next morning Minerva went to Diagon Alley to get baby supplies for Harry after placing a glamour charm to cover his scar. Her and Albus had decided nobody outside the professors at Hogwarts should know that Harry was with them. It had only been a week since Voldemort had been vanquished and shops were still only just starting to reopen so there were very few options for Minerva. She went into Madam Malkin's and was greeted by the kind shop owner.
"Hello Minerva, how are you today. and who is this adorable baby boy?" she asked.
"Hello Ida, I am well , this is my great nephew James. I took custody of him after his parents were killed in the final rampage by Death Eaters." Minerva replied. "I was watching him that night."
"Yes, there were several children left without parents that night, including little Neville Longbottom and Harry Potter. It is very sad indeed." Ida said shaking her head. Anyway, how can I help you today? "
"Well, all of James' belongings were lost in the fire the Death Eaters set to house. I need to buy some clothes for him" Minerva replied.
"Well then let's get started."
By the time Minerva left Madam Malkin's, she had several sets of baby robes that were charmed to grow with him for the next six months. She continued to shop and when she returned to Hogwarts later that day she had all of the supplies a magical child of eighteen months would need: magical books including The Tales of Beedle the Bard, in which the pictures move to help the child understand better, a child's broom that only floated about two feet in the air and a small wand that shot no-burn sparks when a child waved it and several other educational toys.
When Albus walked into their chambers and saw all the toys strewn about he chuckled to himself, his wife was going to spoil little Harry. Albus had not really like the idea of the child growing up at Hogwarts, he needed him to be tough when he was older and to trust Albus explicitly when he returned to the magical world when he was eleven. Having the child here though placed him in an even greater position to gain his trust, he'd just have to find some other way to make the boy strong, mentally and physically. Minerva did not know any of the ulterior motives behind Albus' decisions, and she would not be happy if she did. His thoughts were interrupted by their subject walking into the room.
"Oh Albus, I didn't hear you walk in.'
"I'm sorry my dear, I was thinking we should probably tell the staff that Harry is here today at the meeting. They would be delighted to see him, although Severus may not be so happy to be James' child." Albus said
"Yes, Severus can hold a grudge longer than any goblin, and he does have his reasons. James and the Marauders were never really punished for the way they treated him. I should have been harder on the boys, they were cruel to Severus , even if James to later apologize to Severus for nearly getting him killed, Sirius never did. Maybe that should have been a sigh to us of his dark nature and eventual betrayal. "
"You are correct as usual, Min." Albus said, sighing.
At the staff meeting later that day Albus told the professors about Harry's treatment by his relatives and about his and Minerva's guardianship of the boy. The reactions of the professors were all pretty much the same across the board: anger at the Dursleys and relief that Harry had been removed from that situation. Even Severus was angry, not just at the Dursleys, but also at Albus. He knew how jealous and bitter Petunia was at Lily for being magical and leaving her behind in the Muggle world and Albus knew also, he should have known Petunia would not treat Lily's child right.
"Do you expect us to help you raise the child, Albus?'' Severus asked.
"You do not have to have any interaction with the child if you do not wish to Severus," Albus replied, "although he will grow up here, so you will see him eventually. This concludes the staff meeting for today. Have a good day, I will see you all at dinner.''
Everybody got up and started to leave, Madam Pomfrey walked up to Severus after the meeting. She was one of the few people not in the order who still treated Severus fairly even before it was made known that Severus was a spy among the Death Eaters.
"Madam Pomfrey, how may I assist you?''
"Hello Severus, I was just letting you know that I needed some potions for my supplies in the infirmary."
"Which ones do you need?''
"Nutrition potions, bone mending potion, bruise salve, pepper-up potion and fever potion. " the medi-witch replied.
"I will get them to you in a week. "
"Thank you, Severus."
A week later Severus took the potions up to the infirmary. When he walked into the school's hospital he saw that Minerva was sitting on one of the beds with a small, dark haired child in her lap.
"Hello Severus, would you like to meet Harry?''
Severus walked up to the bed intending to tell the older woman that he had no desire whatsoever of being involved with the spawn of James Potter. That was until he saw the child's eyes. They were the same brilliant green as Lily's, and then the child did something else completely unexpected: he smiled at him and reached up to Severus like he wanted to be held by Severus. He felt a little smug at the notion if James Potter's child wanting to be held by Severus Snape. Potter would be rolling in his grave. Severus picked up the child and smiled back. Revenge was sweet, he would help raise Potter's son.
