Harry yawned as he stretched and made his way down the stairs, it had been a long night. Aside from having his first date with Blaise, he had found his entire group of friends giggling and waiting for him in the Gryffindor common room when he had returned from the date.

They seemed to have made a party of it considering the butterbeer and sweets and chocolate spread all over the common room. Though the minute he walked through the door he had quickly been pounced on and shoved into the middle of the group to tell them, in detail, how the night had went.

Which meant this morning he was not feeling his best as he stumbled down the stairs to breakfast. Honestly next time Blaise took him on a date he was going to insist on a Friday or a Saturday, at least that way he could sleep in the next day a little after being grilled for information.

He yawned again and grinned when Neville captured his hand and tugged him out of the common room, leading him down to breakfast. He might admit that he had had a long week of sleepless nights over the last week as well worrying about the date.

He was lost in warm thoughts of the date the night before, and the sweet last kiss they had shared in front of the Gryffindor common room where Blaise had insisted on walking him to, so he was a little confused when Neville suddenly dropped his hand like it had burnt him and shuffled a few steps away. Looking around his eyes quickly found Blaise, and noticed that his distinctive eyes were narrowed on the space where his and Neville's hands had been joined, and then onto the other boy.

Neville let out a little squeak when Blaise's long legs quickly climbed the first part of the great staircase to where they were standing. Harry found himself getting a little distracted at the display of muscles from the other teen, and before he knew it Blaise was standing in front of him, his expression a little thunderous. He also became aware of two other things, Neville's panting breath from his left hand side, and the fact the area around them was completely silent. Everyone had paused waiting to see what was going to happen, even the Slytherins exiting the dungeon had paused to watch.

Harry let out a loud huff and rolled his eyes at Blaise making the Slytherin blink at him confused, clearly having not expected that reaction.

"Don't be so jealous, Neville is a good friend, that's all, and very straight," He added with another eye roll before moving around Blaise and down the stairs.

"Why was he holding your hand then?" Blaise asked as he followed him quickly down the stairs. Behind them Neville sagged against Seamus as he was let out of the cross hairs.

"Because I was tired and not very aware after being grilled for information on what happened last night," Harry sniffed glaring at Blaise. "He was making sure I didn't kill myself falling down the stairs,"

"I...sorry. Bad habit to get possessive," Blaise muttered, his shoulders drooping slightly as he took in the glare and unimpressed look on Harry's face.

"I am close to my friends, and I like physical contact with them in hugs or holding hands, or leaning on them. If you are going to get jealous every time this isn't going to go well,"

"I'm sorry," Blaise's eyes were blank as he turned to go to the Slytherin table.

"For punishment you're sitting with me for breakfast and lunch," Harry snagged his hand and started toeing the shocked teen over to his normal spot at the Gryffindor table. "And I may be convinced to swap a portion of that close contact with my friends for you,"

Blaise blinked as he was shoved into a seat at the Gryffindor table, the hall going quiet as they realised what they were seeing. Harry sat down contently next to him, and pushing the bounds of their courting a little Blaise shifted so their sides were pressed together.

Neville slunk in with Seamus, Dean, Padma and Luna, the five of them sitting around the two teens, Ron stumbled in not long after they had had time to settle and pour their tea. He blinked at Blaise's presence and the eyes of the Hall on them before shrugging.

"Harry got him whipped already?" He asked conversationally accepting tea from Luna with a blush.

"Yes,"

"Oi!" Harry glared as the others answered first.

"Fair warning mate, you're in serious danger," Seamus said seriously leaning over the table. Blaise blinked and looked at Harry and then Seamus again, glancing to see the others nodding.

"Serious, serious danger?"

"Are you threatening me?" Blaise asked, but he didn't sound angry, rather confused.

"You have made that threat yourself I'm afraid. Harry is very dangerous. Before you know it your will be twisted around his fingers," Ron snickered.

"Guys!" Harry groaned dropping his head onto Blaise's shoulder as his face burnt. The Slytherin blinked before his chest puffed slightly and a pleased look spread across his normally masked face.

"Oh," Luna hummed nodding and then holding out crumpets to Ron who was snickering.

"I see," Dean nodded.

"Poor guy," Neville hummed.

"What?" Harry blinked looking between them.

"Its too late for him," Parvarti said mournfully.

"Will you lot stop!" Harry grumbled.

"Sorry Harry," Ron grinned appeasing the green eyed boy slightly.

Harry blinked when Blaise brushed his fingers gently over Harry's cheek and tucked his hair behind his ear. When he looked up Blaise caught his eyes and smiled gently at him.

"They're right though,"

"He's a keeper," Padma smiled. Harry was blushing darkly but looked very pleased as well.

They ate breakfast fairly peacefully after that, Blaise taking in the difference of conversation and banter at the Gryffindor table to the Slytherin. They were getting some looks, but the acceptance by Harry's group seemed to stop any of the other Gryffindors rom saying anything, and though he was getting some glares from Draco's group, the rest of the Slytherins seemed to be respecting his smooth infiltration into enemy lines.

They stood to go to their first lesson, happily potions so they could go together. Blaise stood and took Harry's bag from him, swinging it over his shoulder with his own, and then held out his arm to the smaller teen. Harry blinked before smiling shyly and sliding his arm through Blaise's. The others around them nodded happily at the action before they walked with them out the hall.

"Blaise! Sitting at the Gryffindor table!" A few Slytherins approached them making Harry draw into Blaise a little, looking up at him worried. Blaise however smirked a little at the others, squeezing his hand a little.

"Seeing as I am courting a Gryffindor, publically, I do not see why me sitting at their table is such a shock," Blaise said dryly. "Harry this is Theo Knott, Adrian Pucey and Daphne Greengrass, people I have been forced to be friends with since I was a boy,"

"Forced! I will remember that one Zabini," Daphne snorted before smiling at Harry. It was slightly calculating, but honest at the same time.

"I recognise you as Blaise's intended," She said formally. Harry's brain went into over drive and he could practically feel the gaze of his friends burning into back as they waited to see if he remembered what they had drilled into his head.

"I thank the Greengrass family, and hope we get to know each other better," Harry smiled.

"Well done," Daphne smiled.

"Does this mean I have lost my potions partner?" Theo sighed. "You're his partner normally aren't you?" He added looking at Ron.

"Oh no!" Harry shook his head. He felt Blaise's arm tensing under his hand and looked up to see the Slytherin looking offended. "No Blaise,"

"I apologise if I have overstepped," Blaise said formally and tried to take a step back, but Harry held onto his arm and glared.

"I don't want to bring your marks down, you second from the top in our year, if you work with me, you will be bottom! I don't want our relationship to affect your school work!" Harry explained.

"What do you mean, surely if you let me help you, and tutor you a little it will be your marks rising, and not mine's falling," Blaise frowned.

"Hate to break it to you mate, and talk bad about your head of year. But Harry is actually pretty decent at understanding potions, that's not the problem," Ron grimaced.

"Then what is?" Adrian asked, his shoulders tensed a little, they could see they were clearly offended at the slight against their head of year.

"Look, if its not Malfoy or his goons throwing something in my cauldron, its Snape swooping out of nowhere startling me just as I am putting something into my potion, every damned time," Harry sighed.

"Sit with me," Blaise said rather than asked.

"I've just told you..." Harry grumbled.

"Trust me," Blaise interrupted shaking his head.

"Fine, just don't complain to me when your grades drop faster than a seeker after the snitch," Harry grumbled making Blaise laugh.

Harry had to admit it was worth it to the see the look on Snape's face when he walked in a saw Harry sitting next to one of his Slytherins. He looked like he was about to have a stroke. And then he looked to the side with realisation on his face and saw Ron grinning sitting next to Theo. Harry had to bite back the urge to wiggle his fingers cheerfully at the professor, and instead sat with a small smile, his knee and thigh pressed pleasantly against Blaise's.

It was also quite amusing to watch how torn Snape was as he battled with his natural instincts to put Harry off and ruin the potion, and against ruining one of his Slytherins potions.

It seemed he couldn't help himself a few times, but Blaise would always steady Harry before he could do anything wrong. One of the times Snape swooped down suddenly Harry started and nearly poured way to much of the powder he was holding into the cauldron. Blaise's hand quickly caught his wrist and steadied him, but his teeth was grit tightly, and he had a vein popping slightly in his forehead.

Harry shrunk a little into himself not sure if he had finally realised what a terrible idea it was to pair up with Harry.

"That could have exploded!" He grit out.

"Its ok it didn't," Harry said softly.

"You could have been hurt!" Blaise snapped. Harry blinked before he felt his heart race slightly. Blaise wasn't angry because their work, and so grade, was nearly affected, but because Harry had been in danger. "I'm sorry I did not mean to snap at you!" He said quickly taking in the blank look on Harry's face.

"Its fine, honestly," Harry smiled, risking pressing his cheek to Blaise's arm before he turned back to add the correct amount of powder before their time ran out.

They could see the urge had to knock the potions vial off the table with their perfectly prepared potion in it, when Blaise placed it on his desk. Blaise obviously also spotted this urge and his eyes narrowed dangerously before he spun and caught his and Harry's bags, leading Harry from the room with a hand on his back.

"That was brilliant!" Ron hooted as soon as they were a safe distance away.

"We apologise, we did not realise he was that bad," Theo said, his own teeth grit a little.

"I've gotten used to it," Harry shrugged.

"You shouldn't have had to," Blaise sighed.

"Where are you going? You don't have transfiguration now," Harry blinked when they reached the corridor they should have parted on but Blaise carried on steering him to his classroom.

"I will walk you there," Blaise shook his head.

"You could be late for your next lesson though!" Harry protested.

"Don't fight him, he's been taught to be the ultimate gentleman," Theo rolled his eyes.

"Why are you coming with us then?" Ron asked curiously.

"Because it amuses me to watch the great Blaise Zabini fawn like a 13 year old Gryffindor,"

"Oi!" The Gryffindors in their group protested.

"Sorry sorry, figure of speech!" Theo laughed.

"You could at least say Hufflepuff," Harry huffed.

"Hey!" Justin grinned as he reached them. "I heard that,"

"Well you guys are into all that cute, touchy feely stuff," Harry teased.

"I will remember that Harry Potter!" Hannah stifled her laughter.

"In return for such abuse, I will accept help with the DADA charm we need to learn this week!" Ernie sniffed haughtly.

"Are you having problems with it?" Harry asked concerned.

"Can't get the damned thing to work," Ernie admitted deflating slightly.

"Me either," Hannah grumbled.

"I can't," Neville admitted.

"Me either,"

"Nothing,"

"I get a spark...not sure that's right or just me though," Seamus grimaced.

"Why didn't you just say!" Harry scolded. "Right, is everyone free this evening? We can meet up and I will run through it with you,"

"Hufflepuff have quidditch practise, would you be able to make it around 7?" Justin asked.

"Of course," Harry smiled. "Let anyone else struggling know they are welcome to come too,"

"Slytherins welcome?" Theo asked cautiously. Harry suddenly found every eye on him waiting for his answer, including a suddenly tense Blaise.

"Of course, we meet at the Room of Requirement. We can have supper together and I will show you where it is," Harry smiled.

"You might as well just start the DA up again," Lavender said casually.

"Guys!" Harry groaned.

"What's the DA?" Theo asked.

"I will tell you all later, for now, you guys need to get to your own class. See you at lunch?" Harry asked unsurely.

"Of course," Blaise smiled. He dipped his head and pressed a fairly chaste kiss to Harry's lips. Harry gripped his shoulder and pressed deeper before he let the blinking Slytherin go with a grin.

"See you later," Harry threw a teasing wave over his shoulder as he went into his class, hearing the teasing comments from the Slytherins to Blaise.
