Disclaimer: I just came up with the O/C's. The rest belongs to JKR.

A/N: I just wanted to thank you guys for your continued supportive reviews! I also have been reading back over past chapters, and I realized that there are question marks where there should be ellipses. I'm really sorry about that, and I'm going to try to fix it! I have a friend coming into town tomorrow, so I'm not going to be able to update for awhile. I'm sorry, it bugs me when stories I'm following aren't updated on a regular basis, so I know how annoying that is! I promise not to forget about my fic, and that I'll have the next part up ASAP! In the meantime, enjoy!

"Severus, I'm not so sure this is a good idea." Rosemarie slid uncertainly off the desk, and pulled the slip back over her head.

"No!" He practically shouted, his voice full of panic.

Rosemarie grinned at the look of horror on his face. "Why Severus!" Her voice was filled with mock surprise. "I didn't know you cared! I was just going to say that I don't think you desk is such a good idea, and suggest that maybe we." She gestured towards the bedroom.

He grinned wolfishly back at her. "You're a damn fine woman Rosie."

"I'm going to go get settled. Why don't you make sure the door is locked?" She winked at him, then walked, hips swaying, into his bedroom and closed the door.

Snape dashed about the room, shirt off and belt undone, making sure there was no way he would be interrupted again. He was just about to lock the door, when someone knocked sharply. Barely suppressing a groan of disgust, he yanked the door open.

"I came for a talk, Father." Simon glared at him, before pushing his way into the room.

Severus felt his stomach jerk nervously, but hid it behind an equally evil glare. "Well. What is it?"

"My mother feels that Emma and I should develop a relationship with you, seeing as how you are our father. Because we love our mother, and want her to be happy, we've agreed. There is one condition though. You have to stay away from Mum-I don't want to see you anywhere near her. You've made her cry too much so far, and I'm not going to let it happen again."

"And this mother you're so bent on protecting, this is the same one who lied to you about your father, and tried to keep you from having a relationship with him?" He couldn't help sneering.

Simon's eyes darkened. "I love my mother, and I will do anything I can to protect her."

"What makes you think I should listen to anything you say?" He snapped at the boy. "Not only am I your father, but I am also a Hogwarts professor. I do not have to do what one of my students tells me to."

"If you ever touch my mother again, I swear to you I will make sure she hates you forever. Who do you think she'll listen to? Her adoring son or the man who wouldn't have anything to do with her for eleven years?" Simon's voice was dangerously low, and as he and his father glared at each other, they looked remarkably similar.

Snape nodded. "You can go now. I'll make arrangements for us to have a meeting." He held open the door for Simon to leave.

"Just remember what I said." Simon glared at him one last time before stalking from the room.

Snape closed the door behind him, and locked it quickly. He paused before shaking his head to clear his thoughts and walking into the bedroom.

Rosemarie was sitting upright on the bed with her robes wrapped tightly around her body. "I can't believe Simon said.yes I can." She corrected herself and smiled wanly. "He hates you."

Snape let out a snort. "Because I'm his hateful potions professor or because I turned his mother into a Scarlet woman?"

"Both." She sighed. "I was thinking that the three of you could spend tomorrow together."

"So I suppose this means sex with you is out of the question for this evening." He leered at her.

Rosemarie shot him a look. "Oh, that's romantic." Her voice dripped with sarcasm. "Do you think I'm going to sleep with you right after my son came in and threatened you?"

"It's been too long Rosie. Especially when I think about all the missed opportunities. All the times I could have pulled you in here and made love to you." Somehow, he had moved across the room and was now right in front of her.

"Severus I have to go." Her voice was little more than a whisper.

"No you don't. You need to come." His grin was wicked. "And so do I."

Rosemarie reluctantly pulled away from him. "I'll bring the twins by at one tomorrow."

"Rosie, you don't want to go."

She shivered slightly at the sound of his voice. "Good night Severus." Rosemarie nearly ran out of the room.

At precisely one o'clock, Rosemarie ushered a terrified Emma and a belligerent Simon into Snape's quarters. "Hello, Severus!" Rosemarie said with false cheerfulness. "I expect the three of you will want to talk and catch up, but I had Simon and Emma bring their homework with them also. Simon, Emma, why don't you two go make yourselves comfortable?" Emma sat down timidly in a straight-backed chair, folding her hands in her lap. Simon glared at his father, crossed his arms, and threw himself into one of the armchairs by the fire. "Well, I had better be going. I have some tests to grade, and silly me I didn't think to start them earlier. Have a good time!" And with that, Rosemarie beat a hasty retreat from the room.

Snape nervously cleared his throat. "Well. Since you two brought your homework with you, you may as well get started on it." He walked over to his desk, and sat down uncomfortably behind it.

After ten minutes of deafening silence, Emma walked over to Snape's desk. "Father?" Her voice was no more than a whisper. "Would you help me with my potions homework?"

Snape looked up from the parchment he was grading. "I do not help my students cheat, regardless of whether or not they are related to me."

Emma's face got red with anger, and she reminded him uncannily of Rosemarie. "It's not cheating. It's called helping. Mummy helps all her students if they're having a problem with a difficult counter-curse or spell."

"Be that as it may, I refuse to give you the answers. I'm certain you can figure it out on your own."

Simon gave a snort of derision from his armchair. "Well maybe she could if our potions professor wasn't such a bloody, useless git."

"Simon, come to my desk. Now." Snape barked.

"Whatever you say, father." Simon spat at him.

"We are going to deal with this situation as best as we can. This is not the way I would have chosen to get to know my children, but so be it. You can at least be civil."

"As civil as you are being to us?"

Snape muttered a string of curse words under his breath as he sat back down at his desk. He was still in a think cloud of anger, when he caught Emma staring at him intently a few moments later. "What is it Emma?"

"I think it's so romantic, you and Mummy meeting again after all these years. It's just like something out of a romance novel. I know exactly how it all happened. Mummy told me."

"Oh did she now?" Snape was amused.

Emma nodded eagerly, eyes sparkling. "Oh yes. You were a spy at the Ministry. Mummy was just a lowly assistant. She was charmed by your debonair good looks and cavalier treatment of the fairer sex. She wasn't like the other women you dated-she had a brain and wit, and challenged your sense of masculinity. You decided to woo her, in an attempt to teach her a lesson and regain your sense of manhood. Yet, in spite of it all, you found yourself falling in love with her. You were caught in a spiral of love and intrigue, until finally you couldn't take it anymore and you gave into your carnal urges. That's where Simon and I come in. She thought you betrayed her, but really you were just trying to protect her. You spent the last eleven years alone, wallowing in your misery and dreaming of her every night. Your one and only. Your elusive Rosemarie." Emma sighed in contentment.

Snape was completely speechless, and his face was red with embarrassment. Simon on the other hand, was not. "Emma, where do you come up with crap like that?"

"The books that Victoria lends me." Emma replied defensively.

Simon shook his head in disbelief. "You have no sense of reality.

"I do so! He must have changed since Mummy knew him! Can you imagine her falling in love with some miserable, crabby bastard like him?" Emma's face got red as she realized the him in question was standing behind her and glowering.

Simon looked at her in astonishment. "I do believe that's the first time I've ever heard you swear, Em."

Emma whispered something that could have been "I'm sorry Professor Snape" and took her books over to the farthest corner of the room.

Simon, however, was nowhere near done. "If Mum doesn't fall in love with crabby bastards Em, then maybe you could explain to me why I caught this crabby bastard shagging her brains out the other night." He smirked at his father.

Emma shot Snape a horrified glance before turning to her brother. "Simon, that's disgusting. You shouldn't say things like that about Mummy."

Simon just shrugged. "It's true. He could barely keep his hands off of her."

Snape had finally reached his breaking point. "Simon. I have had enough of your behavior. If you choose to behave like a four-year-old, so be it. I did not choose to have things up the way they did, and if I had my way, my son would be a very different person. I am trying."

"Bullshit." Simon cut him off. "You just want to get back into Mum's pants, and you figure sucking up to Em and me is the easiest way."

The old, menacing gleam returned to Snape's eyes. "Believe me Simon, I don't have to give you two preferential treatment to, as you so succinctly put it, get into your mother's pants." He paused for a moment, and against his better judgement, said what the evil imp in the back of his mind was thinking. "She's just as hot for me as I am for her, you know."

Simon's face went dead white, and he would have surely attacked Snape, but for one small detail.

Emma got there first.

She flew at her father, screaming at the top of her lungs. "How can you say those things about Mummy?" She beat him mercilessly with her fists. "She has never, ever said anything bad about you! Even when Simon and I said you were the meanest teacher ever! You are a horrible, horrible man! I can't believe she ever let you near her!" Emma's final word on the subject was punctuated by her spitting at Snape. "Come on Simon, we're leaving." Simon just stared at his sister in astonishment. "Simon!" She bellowed. "Let's go!" Bewildered, Simon followed his sister towards the door, only to run headlong into their mother.

"What's going on in here? Simon? Emma?" Rosemarie looked questioningly at each of her children, before turning her gaze on Snape.

Snape's piercing stare faltered. "Simon started it!" He said defensively.

"Oh for heaven's sake! I was hoping that you two would be able to talk civilly with your father, but apparently I hoped for too much."

Emma was still furious. "You should have heard the things he was saying about you! Simon and I tried to get along with him, but it's hard to do when he says things like that about your mother."

Rosemarie's eyes narrowed. "What things?" She asked, without turning her gaze from Snape.

"He said it doesn't matter if he's not nice to us, you'll shag him anyway. I believe his exact words were 'She's just as hot for me as I am for her, you know.'" Simon smirked at his father's shocked expression.

"Severus. May I speak to you privately for a moment?" Her voice was deceptively polite, and her knuckles were white as her hands clenched at her sides.

"Oh no, we aren't going through this crap again." Snape was equally furious now. "You have something to say to me, you say it now."

"I know your childhood was awful. I know your experience at Hogwarts was awful. I know you have lived quite possibly the most horrific life known to man." Try as she might, Rosemarie could not keep the sarcasm out of her voice. "But honestly, was there ever a period in there when you learned some rudimentary social skills? These, are your children!" She spoke to him as though he were a small child. "You don't try your hardest to make them cry within the first half hour of speaking to them." She sighed resignedly. "Maybe I was hoping for too much. I think we had better leave it, don't you?"

"Leave what?" Snape's voice dripped with suspicion.

"It's clear to me that you really don't want anything to do with us. Or perhaps, you just need some time. Whatever the case, maybe we shouldn't have the three of you meet again for some time."

Snape's face was suffused with anger. "Fine. Take my children away from me again. You really are getting quite good at this."

"Oh honestly!" Simon's exasperated voice rang out. "Do the two of you have to fight over everything?" Both of his parents and his sister looked at him with shocked expressions. "I hate him as much as you do Em, but this whole thing is getting pretty stupid." Emma just glared at her brother in response.

Rosemarie surveyed her children with a dismayed expression. "You two are right you know. What kind of example am I setting for you when I fight with your father all the time?" She paused. "Maybe the four of us could try having a family meal together. No fights, all of us on our best behavior. And especially no childish insults." She shot Snape a pointed look.

"You had better take your own advice, Rosemarie." Snape said through clenched teeth.

She shot him a withering glare. "If that remark was intended to imply that I insult you on a regular basis."

"Mum." Simon cut her off warningly.

Rosemarie's sigh was both tired and resigned. "Very well." She turned to Snape. "The three of us will be here tomorrow night for dinner at 5:30."

He shot her a look in response. "The Great Hall isn't regal enough for you?"

"Well I thought, perhaps, it would be easier if our first meal as a family wasn't held in front of hundreds of curious eyes. Unless of course you want to announce to the entire school that your two illegitimate children are now currently attending Hogwarts?"

Rosemarie saw Snape visibly bite back a retort. "Fine. I'll make arrangements with the House Elves."

"See you tomorrow then." She replied with false cheerfulness, before taking Simon and Emma by the hand and leading them through the door.

To say that the family dinner went well would perhaps be a bit of an overstatement. Rosemarie and the children arrived promptly at 5:30. The air was thick with tension, Rosemarie's palms were moist and her mouth was dry. Snape greeted them politely, if not a trifle coldly. Simon threw himself into one of the chairs around the table, and refused to speak to anyone. Emma slipped quietly into her seat and commenced a detailed examination of her plate. Rosemarie cleared her throat uncomfortably. "Everything looks lovely." She gestured towards the food.

"Well, only the best for my adoring family." Snape replied, his voice dripping with sarcasm.

Rosemarie's left eyebrow went up. Fine, if he wanted to play it that way, she was more than capable of competing. "I'm so touched to see that you're taking this seriously, Severus. You aren't being an arse at all." Her voice was equally sarcastic.

"Quit it you two." Simon snapped at them.

Rosemarie and Snape looked at Simon, but refrained from commenting. The room was completely silent for a few moments, before Rosemarie asked, "Could you pass the bread, please?"

"Certainly." Snape replied. His eyes, however seemed to say. "You bitch queen from hell."

"Thank you." Rosemarie's smile in response told Snape that she thought he was no better than a fly-infested cowpat.

"Rosemarie, would you pass me the pumpkin juice?" His silk-smooth voice implied that Rosemarie looked like the back end of a bus.

"Here you are, you smug narcissist." Rosemarie couldn't help herself, the insult just slipped out.

Snape looked at her with a light of triumph in his eyes; now that she had insulted him openly, anything was fair game. Completely disregarding the quelling looks Simon was attempting to send his way, Snape let all his pent- up emotions fly. "A narcissist, am I? So what would that make you? Queen of the Harpies?"

Rosemarie just rolled her eyes. "Severus, we've been fighting for over fifteen years, and that's still only the best you can come up with? You really are as stupid as you look."

Snape's knuckles went white around the glass he was holding. "Oh yes, considering you were the one who was too dense to figure out that I was a double agent, and not betraying everyone our side."

"Just as you were so astute in figuring out that I was pregnant with your children. I came to Hogwarts the day the twins were born you know. You even spoke to me. Only you were too much of an imbecile to recognize me and figure it out."

"Oh yes, it really is a pity I have yet to master the art of mind-reading, considering it's something that very few, if any, wizards can do."

Rosemarie felt her eyes spark. She knew how to put an end to this. "Oh, grow up Snivellus."

In all her years of fighting with Snape, Rosemarie had never really been afraid of him, until that moment. The look on his face was lethal, and there was a sudden cracking sound, as the glass in his hand shattered. "How dare you use something I told you in confidence against me, you disgusting half blood?"

Simon and Emma were terrified now. Their mother looked as though she was on the verge of tears, but at the same time, ready to explode. "Well, it's nice to know what you really think of me. Tell me, Severus, what is it that makes half bloods so disgusting? Is it that we're uncivilized? Does the Muggle half of us take over, and suddenly turn us into savage beasts?" She paused for effect, and stood up from her seat. Are we just so accustomed to living in filth" here Rosemarie picked up her dinner plate, which was still loaded with food "that we are unable to conduct ourselves with decorum?" Emma looked at her brother. Her mother really wasn't going to throw her plate, was she? "Well, I would hate to let you down Severus, since you were clearly expecting a show this evening." The words were barely out of her mouth, before she let the plate fly from her hand and crash into the wall opposite.

Snape stood up from the table. "What the hell do you think you are doing, Rosemarie?"

"What does it look like I'm doing?" Crash! A dish went sailing through the air, and splintered against the wall behind Snape. "I'm acting the way a half blood would in this situation." A glass and a serving plate quickly followed the dish into death.

"Rosemarie! Will you stop behaving like a child?" Snape shouted as another glass went soaring past his head.

"I'm not behaving like a child, Severus." Crash! "I'm behaving like a half blood."

"Your behavior is embarrassing, not to mention completely disgusting. Although, I should have known by now not to expect any less from someone like you."

Rosemarie set the bowl she was holding back down on the table, and looked Snape straight in the eyes. Tears had started to run down her face, and there was food spattered across the front of her robes. "I may only be a half blood, but I would far rather be that, than a cruel, heartless full blood like you. I would rather my children be Squibs or Muggles, than have them be anything like you." She turned slowly, and left the room.

Snape stood there stupidly for a moment, with Simon and Emma just staring at him. "What are you two staring at?" He snapped. "Go on. Follow your mother, just like always." When they made no signs of moving, Snape lost his temper. "Get out!" He bellowed. Emma didn't have to be told twice; she jumped out of her chair and ran for the door. Simon, however, stood his ground, and stared unflinchingly at his father. "What did you not understand? Have all these years of living with half bloods affected your mind? Get out!"

Simon just stared at his father. "If you really loved her, you wouldn't have said that."

"She insults me, and that's all you have to say?"

"If you really loved her, you wouldn't have done that to her." Simon reiterated before getting up from his seat and leaving the room. After the door closed behind him, Snape stood staring at the damage in the room. He let out an anguished roar, and let the remaining glass on the table fall to the floor with a satisfying smash.
