Disclaimer: I don't own Harry Potter

A/N: Thank you all for the good wizarding world date ideas! I'll see about working one or two in here :)

Harry's Tuesdays started with Transfiguration then Charms. He had a break for lunch and then had double potions with the Gryffindors. He was certain Dumbledore was trying to torture his dad by always putting them together in Potions. Harry packed almost Castor's entire room in his diaper bag that he had magically made bottomless and featherlight. He had no clue what they would need in order to get through a day of classes without a meltdown. Castor was a wonderful baby, but a tired baby can only take so much.

Harry got to the Great Hall early and found Pansy by herself at the table, nursing a cup of coffee. "Not a morning person?" He asked.

"No until I'm two cups in," Pansy said motioning to the coffee cup.

"I'm more of a tea person myself," Harry said as he, kindly, shoved a bottle into his fussing son's mouth. Castor was still being introduced to solid foods, but his main nourishment would continue to be a bottle for a while. Harry held the bottle for Castor with one hand while he ate his bacon and eggs with the other.

"So, how long were you with his mother?" Pansy asked, almost making Harry choke on his eggs. He hadn't really been planning for that question.

"Not long enough," he said, thinking of how he wasn't able to help the abused selkie. Pansy just nodded and let it go, realizing he didn't want to talk about it. "You got Transfiguration?" He asked to change the subject.

"Yeah, I'll show you how to get there in this long," Pansy said, motioning to how much coffee she had left in the cup.

Oh yeah, he wasn't supposed to know how to get anywhere. He might have to remind himself of that for a while and avoid all the secret passages he frequently used. "Thanks," he laughed.

True to her word. Pansy rose to take Harry to Transfiguration once she finally finished the coffee. They passed Draco and Blaise entering the Great Hall. "You're going to be late," she scolded them.

"We're just grabbing toast!" Draco said as they hurried past.

"And you thought I wasn't a morning person," she said with a raised eyebrow to Harry. Harry shook his head, confused and amazed at how normal and even helpful the Slytherins were towards him. He didn't know how much of it was his baby's selkie aura, the fact that he was Snape's son, or that he just wasn't used to being treated like a normal person. Whatever it was, he was enjoying the change immensely.

Harry and Pansy took seats on the end of a row and Harry set up the playpen for Castor who immediately began to play with his fluffy hippogriff (that Harry had taken to calling Buckbeak in his head). Harry then cast a silencing charm over the playpen and put the baby monitor crystal in with Castor. "Smart, thinking Mr. Snape," Professor McGonagall said walking by them. "Did you do the transfiguration of the crystal or did your father?"

"I did ma'am. I also did the charm work," he said proudly. He planned to take the Sorting Hat's advice and no longer try to aim for the middle of the class. He wanted to learn and do well. His goal to stay as invisible as possible before led him to not do his best in classes. He had to also begrudgingly admit that he and Ron probably weren't the best influences on each other either.

"I believe that's 5 points to Slytherin then," she smiled as the rest of the class filtered in.

Castor made it through all of Transfiguration and half of Charms before he had a meltdown. Harry was pretty sure he needed a diaper change and some attention from his dad. When his crystal started to vibrate with Castor's silent cries beside him, Harry stood and lifted Castor out of the silencing bubble causing everyone to hear a few loud wails before he left the room. "We will not be calling in Dobby on our first day, Cas. We got this right?" He said as he found an empty alcove where he could change the diaper.

Harry made it back to class with a much calmer baby right as Flitwick was ending. Harry sighed but Blaise waved his wand over his notes to duplicate them and handed a copy to Harry. "Wow, thanks!" Harry exclaimed, thoroughly shocked.

"No worries. Just like Snape said, we look out for our own."

Instead of going to lunch in the Great Hall, Harry had Dobby bring him some food in his quarters. He figured Cas could use some time to crawl (or rather scoot since he wasn't quite at crawling yet) around and not be around people constantly. Before he knew it, it was time for Potions though. He was both excited and dreading being in class with his old friends again. He didn't know how to act around them, and they had no clue who he was.

Harry walked into the classroom in the dungeons and found a seat at Draco and Pansy's table. Apparently, Blaise was crap at Potions and had dropped (Pansy's words). Right after Harry and Castor settled beside Draco, Ron and Hermione entered, chatting together about something. "You'd think the Weasel and the Mudblood would be more concerned with their missing friend," Draco sneered.

Unfortunately for Draco, Professor Snape had just walked by their table. With a flourish, he deposited a jar on the table in front of Draco. "That'll be one knut," he said with a cold look. Written largely across the jar was "Swear Jar."

"You can't be serious, Professor," Draco protested.

"Deadly," Snape glowered. "I mean it when I say that my grandson's first words will not be a swear word."

Snape then turned to Ron who was sniggering. "That goes for you too, Mr. Weasley. I've heard you talk to your friends, and I suggest you watch yourself before you bankrupt your family."

After Draco dropped a knut into the jar, Snape took the jar and Castor from Harry. He deposited the jar on his desk, in full view of the class, and Castor in a comfortable looking play area to the right of his desk and behind the chalkboard for extra protection. "Be good," he warned the laughing baby softly.

And, with that, the snarky potions master was back. If they didn't have the swear jar shoved in front of a couple of them, they would never have known that he was anything different than he had been every other class in their six years. Harry, however, was loving the class. Though nothing had changed for the majority of the students, for Harry, everything had. The Slytherins weren't trying to sabotage his potions, and Snape was giving him neutral attention instead of being outright hostile. He definitely wasn't being favored, not that anyone would have expected that from the professor, but at least he wasn't being yelled at and sneered at constantly. So, Harry was immensely proud of the potion he turned in at the end of class.

That night, with Castor cuddled under his wings, Harry slept the best he had slept in a long time. Castor always seemed to keep his nightmares away, but flying on the high of his success in the day, and being just physically exhausted, led him to sleep deeply.

Wednesday brought his first Ancient Runes class and double DADA with the Gryffindors. Harry decided he was really going to like Ancient Runes. It was much better than Divination at the very least. He even sat close enough to Hermione that he was able to say hi to her before the class started. She gave him a little smile and said hi back, but that was all the interaction they had before class got going. Even though Harry was taking Runes at the OWL level and Hermione was doing NEWT level work, the classes were combined with their assignments and projects being tailored to the two different levels. He hoped he would be able to get Hermione's help with the material at some point in the future. If not, Draco was also in the class doing NEWT work, but he really missed Hermione.

When Harry got to Professor Lupin's class, he saw a similar set-up in the corner of the room for Castor as there was in Potions. This was another class that was a bit dangerous for a baby to be out and about in, so Harry was happy to deposit Castor in his play area with the monitor crystal before taking a seat by Blaise. The class groaned as one when Lupin pulled a familiar looking jar out of his desk and set it in their view. Lupin shrugged. "Professor Snape talked me into it. I believe the going rate is a knut per swear word."

It only took until the next day before every professor in Harry's classes had a similar jar on their desks. "Everyone's going to hate me," Harry groaned after McGonagall pulled one out in their double Transfiguration class.

"Nah, the baby's too cute," Pansy smiled. "I'm ok parting with a few knuts for those gorgeous blue eyes."

Harry dragged himself into the Great Hall for dinner. Thursday nights were Astronomy at midnight. He had no clue how he was going to make it. Carrying a baby around all day as well as attending classes was harder than any quidditch practice he had ever had. He had just got settled beside Pansy when Snape came up behind him, making him jump. "I hear I'm on babysitting duty," his dad grumbled softly.

"Not until bedtime, Astronomy's at midnight," Harry smiled at him, thankful he was willing to watch Castor after he went to sleep.

"Nonsense," Snape frowned. "You need to rest and take a nap before class or you'll be useless tomorrow. Now, hand over my grandson. I haven't seen him in days."

"You saw him yesterday," Harry said handing Castor and the diaper bag over.

"That was class, doesn't count," Snape said as he took the baby with him up to the head table. Where he saw Remus reaching for a pudgy little hand as soon as they were seated.

Harry sighed and smiled at his new friends in front of him. "So, how does it feel to be baby-less for the night?" Blaise asked with a smirk as he filled his plate.

Harry laughed. "I'm hopeless. I miss him already."

"Well, I for one plan to swear up a storm in class tonight," Draco laughed.

"Maybe we should start up the swear jar in the dorm," Pansy said, giving Draco a playful push. Draco laughed and gave her a quick peck on the lips.

Harry blinked. How had he not noticed they were together. He had almost been obsessed with Draco the year before and what he was up to, and he had been hanging out with them every day since classes started this year. "Erm, how long have you two been together?" He finally asked.

"Just since the summer," Pansy said, pushing some mashed potatoes over to him. "Draco had to move out of his family's house at the end of last year."

"It was a difference in ideals between my parents and I," Draco explained.

That was an understatement, Harry thought. He knew Draco's father had cursed him with the Cruciatus when he learned that he had gone to Dumbledore to seek protection from Voldemort. Draco had then been promptly disowned, or at least Lucius had tried, but Draco's grandfather had made several provisions in his will that kept Lucius from being able to disown his son. Apparently, Abraxas Malfoy had gotten close to baby Draco before he died and meant to ensure he was always taken care of. At least, this was the story Harry had heard from Snape over the summer.

"Yes, well, Draco moved in with Blaise, who happens to be my neighbor, so we hung out a lot this summer," Pansy finished.

"Don't you normally hang out during the year?" Harry asked, confused. He was sure he had seen them together, but usually with Crabbe and Goyle as well.

"Nah, Draco's dad wouldn't let him," Blaise explained while Draco looked down at his plate. "Crabbe and Goyle over there were instructed to keep him in line and away from anyone old Lucius disagreed with and to make sure he acted the part he was expected to play. So, Draco was always watched whenever he was around us. Lucius was always a right bastard."

"I'm sorry, Draco," Harry said, truly sorry he didn't know the boy had been controlled all those years.

Draco just shrugged it off. "I'm a Malfoy, even if my father doesn't remember what that means anymore. I will bow to no one."

"At least you don't have to deal with those two morons anymore," Harry motioned in Crabbe and Goyle's direction. The two were shooting them murderous glances occasionally though they hadn't attempted anything yet.

"Yeah, I think I lost brain cells every minute I was around them," Draco snorted.

"Well, let me know if they bother you, or don't, depending on how messed up you want them to be," the Fury smiled at him, showing some fangs.

"That's creepy, dude," Blaise shuddered. "The baby really tones you down."

Harry had fun with his new friends at dinner and hung out with everyone in the common room until time for Astronomy class. Slytherin dynamics were definitely more intense than Gryffindor ones, but he found himself up to the task of playing the politics. Crabbe and Goyle were definitely going to be a problem though as they continued to give Harry and his group murderous glares whenever they walked by. His best guess was that Nott and Bulstrode were also with the Death Eaters from their animosity towards him and his father. Even in the midst of all this, Harry actually felt like a normal teenager again for just a little bit, not that he didn't miss Castor every second.

They were making fun of Blaise's abysmal potions skills on their way to Astronomy class when they turned a corner and Harry almost ran right into Ron who was walking with Hermione and Seamus. "Watch where you're going, snake," Ron grumbled nastily as he pushed past Harry.

Harry was not giving up that easily though. He skirted around Ron until he was in front of him again. "Hi, I'm Artie," he said offering his hand. He could see Draco rolling his eyes in his peripheral vision.

Ron squinted at him in confusion. "You're the greasy git's son, right?"

"We replaced his hair products. He was buying all the wrong things. So…better hair now. Didn't you notice?" Harry rambled, not liking how this was going.

Hermione pushed Ron to the side, trying to save the situation. "Yes, his hair is much better now, and that was very rude of Ron. I'm sorry. My name's Hermione."

"Artie," Harry said shaking her hand.

"Where's your tiny shadow?" she asked.

"Oh, it's past his bedtime, so he's hanging out with his grandad," Harry explained.

"Never going to get used to Snape being a grandfather," Blaise snorted behind him.

Ron looked over at Seamus and they continued walking, ignoring the group of Slytherins. "What's his problem?" Harry asked Hermione. He didn't know why Ron was acting so strange.

"He just misses his best friend," Hermione explained. "Erm, he wasn't able to come back this year."

"Oh, you know my friends?" Harry asked. Offering to introduce Draco, Blaise, and Pansy, knowing full well she already knew them.

Hermione seemed at a loss to answer him. "We know each other already, but I don't think we've been formally introduced, I'm Pansy," Pansy offered her hand to Hermione.

"Yeah, Pansy. How's Arithmancy going so far?" Hermione asked.

Harry was fairly pleased with the encounter. Things might have been tense with Ron, and Draco and Hermione may have ignored each other, but Pansy and his old friend really seemed to hit it off. Blaise, well Harry wasn't sure about Blaise. He got really shy all of a sudden, like he had a bit of a crush on Hermione. Apparently, Harry meddled in things like this now, so he found himself watching the two of them and plotted future hangouts when they might be suspiciously left alone together.

Snape walked out of his bedroom in the morning to turn his kettle on to make tea. He stretched and then laughed. Apparently, Harry hadn't been able to go the night without Castor as the two were curled on his couch together. Harry woke as the kettle started boiling. "Good morning."

"How was Astronomy?"

"Good. I think Blaise has a thing for Hermione. I'm thinking we should all go study in the library sometime soon," Harry said as he transferred a still-sleeping baby to his playpen, then stretched his wings. "How was Cas for you?"

"Fussy, drooly, threw porridge at the wall, so an angel as always," Snape said with none of his usual sarcasm.

"Thanks for watching him. I'll just pack up his stuff and we'll be out of your hair," Harry said, folding the blanket they had been using.

"Oh no you don't!" Snape said folding his arms and glaring at him. "I promised Remus he could hold him at breakfast. You are not going to make his godfather mad at me, are you?"

Harry smiled and shook his head. "Ok, but you return him after breakfast. He will not be staying in the Potions classroom all day. I don't want him around the fumes all the time."
