oOoOo

Petunia Dursley had always suspected something as she watched the boy grow but it wasn't until the summer after Harry's third year at that infernal school that she took her reservations seriously. The boy was growing into a more mature look and at first she hadn't really paid that much attention. After all she rarely deigned to actually look at her nephew. Looking at the boy reminded her of too many bad memories from her childhood, too many instances when the darling perfect Lily had outshined her. However it seemed that Lily wasn't quite as perfect as everyone had believed her to be.

She hadn't really thought of her suspicions for a while now. It wasn't until the middle of the summer after an altercation between her Dudders and the boy that her suspicions were brought to the forefront of her mind once more. The boy had been weeding the garden and Dudley had gone out to tease him. Petunia knew that Dudley was a bully that he treated Harry horribly but she turned a blind eye. She thought it was a divine justice for the way Lily had taken their parent's attention from her.

Dudley had gotten a little rough and in the aftermath the boy's glasses had been completely crushed. The boy had begged for contacts and Petunia had reluctantly agreed figuring they would be less likely to be destroyed so she wouldn't have to go out and buy a new pair of glasses again. She had told the boy that she would do it as long as he allowed her to shave his head. She hated his unruly black hair and she reasoned that as long as he had agreed to it than his freakishness wouldn't grow it back. The boy had reluctantly agreed.

Once both the shaving and the contacts had been accomplished the true shape of the boy's face had been revealed and Petunia's paranoia had been piqued once more. Without the shaggy thick black hair and large round glasses covering the top half of his face, his true features had been on blatant display. It had startled Petunia to see the boy and her earlier suspicions had been out in full force. The boy didn't look much like James Potter without his glasses and cover of wild black hair. In fact he looked nothing like the square faced man. Petunia wanted nothing more than to prove to the world that her sister wasn't as great as everyone thought her to be and discovering that her sister had cheated on her husband was better opportunity than she could have hoped for.

To confirm her suspicions she had gone looking for pictures. She had a couple of Lily and James from her wedding with her parents, which was the only reason the pictures had been saved. While she had been looking she came across a picture from her childhood. It was Lily with her childhood best friend Severus Snape they were perhaps thirteen or fourteen in the picture. At first she had sneered to see her two least favorite people in the same photo. She had greatly disliked Severus' uppity attitude towards those without magic and the feelings had been mutual. She would never understand why her sister had so enjoyed the company of the dirty, shabbily dressed boy.

However when she took a second look at the picture it sparked something in her mind. She took a closer look at Severus and she felt her heart skip a beat. In a dazed shock she realized Harry had his forehead, his cheekbones even the shape of the eyes and the almost elegantly arched black eyebrows were the same. How had she never noticed this? She remembered thinking that Harry hadn't looked much like James when he was younger. But she had believed that it was simply because he was a baby and it was difficult to determine if babies looked like parents because they all looked the same.

As he grew older she had thought there was a familiar look to his features but she so rarely looked closely at him and his hair and glasses so effectively hid him that she hadn't thought much about it. Without the hair and glasses however, he looked so much like Severus. It had made her giddy to discover that her pretty, proper sister had cheated on her rich husband with the poor son of the local drunk.

With her new discovery she had quickly taken action. If the boy's father was alive then she certainly didn't deserve to be stuck with the little freak and the discovery that he was Severus' made her even more eager to be rid of him. She'd make sure that Severus took full reasonability for his actions. She would first have to confirm that Severus was the boy's father, so she bought one of those send away DNA kits. Now all she needed was to get Severus' DNA. Petunia had then written a letter demanding Severus' presence. She'd reluctantly commandeered the boy's owl after getting reassurances that the owl could find any witch our wizard once given the name and ignoring his questioning as to why she wanted the owl.

Severus had written back saying that he would come by the next day at noon. Petunia made sure that her Dudders would be out of the house and not exposed to Severus' vileness. She also sent the boy out to do some shopping that would take several hours. Now all she had to do was wait, get a swab of the inside of Severus' cheek and then once her suspicions were confirmed she would finally be rid of the boy. She would have her revenge on Lily and even Severus once he realized Lily had had his child without telling him. When the knock came to the door promptly at noon she smiled and straightened out her already impeccable dress and moved to answer the door.

oOoOo

Severus Snape was not in a good mood. But then again he was hardly ever in a good mood. Today was special however. If his students had seen him stalking down the hallway with the scowl he wore now they'd surely wet themselves. As it was the cause of the scowl was because of an old childhood acquaintance whom he had loathed had practically commanded he come to see her, stating that if he didn't she would come to him. Not wanting Petunia Evans anywhere near his home he had come. He figured that this had something to do with the famous Boy-Who-Lived. No doubt he'd complained about his treatment to his auntie and now Tuney wanted to rip into him. It would be a cold day in hell before he let something like that happen.

He apparated to Privet Drive and made his way briskly to Number Four. He wanted to get this over and done with as quickly as possible. The summer was half over and he would only have so much time to himself before he was forced back to Hogwarts and to teach all of the little dunderheads. The little suburb made his skin crawl with all of the identical homes and manicured lawns and the utter ordinariness of it all. He rapped loudly on the door and waited with barely leashed patience for Petunia.

The door was thrown open and there was the horse-faced Tuney from his memories albeit older and even more shrewish.

"Petunia," he drawled.

"Severus," she snapped back while her blue eyes swept up and down him eyeing him critically and for a moment Severus wondered if he had forgotten to transfigure his robes to suitable muggle clothing what with the way she stared.

"Are you going to invite me in? After all it was you that insisted on this little happy reunion," he said doing his best to hold on to his calm.

"Right come in," she demanded.

He stepped into the immaculately neat house that was a study of ordinary, suburban décor. As she led him into the living room he noticed all the pictures of what he thought was a pig wearing a blonde wig. It wasn't until he saw a family portrait with the pig that he realized that it must have been Petunia's progeny. It was also around this time that he noticed there weren't any pictures of Potter, tons of the small whale but none of the Boy-Who-Lived-To-Annoy. It was odd to say the least. However he didn't bother to dwell on it he was here to discover why Petunia had felt the need to contact him.

"Do you still live in Spinner's End?" She asked conversationally.

"During the summers," he agreed not bothering to explain and she didn't seem keen on pushing for information.

She seemed overly excited about something and fretted with the snacks and tea she had set down on the coffee table.

"So Petunia, why did you so kindly invite me to your lovely home?" He sneered sarcastically as he waved away her proffered cup of tea.

"I'm sure you know Lily had a son?" She said sipping at her own cup of tea.

He stared at her blankly. Was this some sort of joke? Did she honestly not know that he was one of the boy's professors? Didn't Potter regularly complain about him to his relatives? It was almost disappointing to think that Potter didn't complain about him, obviously he wasn't doing his job well enough.

"I'm aware," he agreed wanting to see where she would go with this.

"Did you have any contact with Lily before she got married?" Petunia asked trying to look casual.

But Severus was an accomplished spy there wasn't much that could get by him and Petunia's attempt at casual wasn't fooling him in the least. He still had no idea where she was going with this but decided to just be honest.

"I ran into her once, just before she got married," he agreed.

She nodded a sudden smug look on her features that caused a sense of uneasiness to spread through Severus.

"Are you going to tell me what this has to do with why I'm here?" He demanded, slowly losing the grip on his patience.

"You see I've always had my suspicions about Harry but they truly came to light this summer when he got contacts and a haircut. It brought to light certain features of Harry's that have made me question things about him," she began.

"What are you getting at?" Severus snapped.

"I don't think Harry is James Potter's son," she stated.

"What does this have to do with me?" He questioned in utter shock at her announcement this was the last thing he had come here expecting to hear. There was no way that the spoiled, pampered Boy-Who-Lived could be anything other than James bloody Potter's son. He had the same black hair and the glasses, not to mention the same conceited attitude.

"I think you're his father," she said calmly.

"What! You think I'm Potter's father?" he demanded.

"He looks just like you when you were teenager. I want a DNA test and once it's confirmed I'll expect you to step up and take full responsibility for the boy. I won't have in this house when you are perfectly capable of taking care of your own mistakes," she said and before he could react she shoved a muggle Q-tip in his mouth rubbed it against his cheek. Just as quickly she pulled it out and put it in a plastic container.

"What in Merlin's name was that woman?" He snarled leaping to his feet.

"I needed your DNA for the paternity test I plan on having done to confirm what I've already figured out for myself."

"You can't be seriously considering the notion that I'm Harry Potter's father. Have you gone daft you crazy horse faced shrew?" He shouted.

"I'm perfectly serious you greasy bastard," she snarled getting to her feet as well staring him down.

"What evidence can you possibly have that would lead you to this ridiculous notion?" He demanded, seething inside at such a preposterous claim.

"I told you he looks just like you expect for the fact that he has Lily's eye color, her straight thin nose and fuller lips. You said it yourself that you had contact with Lily a short time before her wedding which would be a suitable time period before the boy was born," she explained as if it was the most reasonable thing in the world.

"Yes I saw her I didn't say anything about sleeping with her! And Potter was born a full ten months after Lily and James was married taking me out of the running for being his father!" He snarled enraged that Petunia would dare bring up such a sore subject with him.

"So you weren't with my sister intimately before her wedding? And it's not unheard of for babies to be born a month late," she said still sounding nauseatingly certain of herself.

He had never told anyone what had happened between him and Lily that night at the end of October. It was a memory close to his heart for two reasons. The first because it was the one night that Lily Evans had actually been his and two it was the last time that he ever saw her alive. It was also a bitter memory because of those exact same reasons.

"Why are you so sure that I am the father of Lily's son?" He questioned barely able to get the words to pass his lips.

It had been his most secret dream to marry Lily and to have children because she wanted them not him; of course he'd grow to love them because they were a part of Lily and a part of him. But those dreams had been crushed when she had married the Golden Gryffindor James Potter.

"Because it will be proof that my pretty, perfect sister wasn't as wonderful as everyone thought she was. My parents, the neighbors and even you all thought the sun rose and fell on her. But once the DNA test confirms it, my sister will be revealed as the cheating slag she really was," she said with such vehemence that it shocked even him.

"Don't you ever refer to Lily as such in my presence," he said in a low dangerous voice usually reserved for Potter or the Weasley twins. "She was far from perfect but she was by no means a slag. Just because she was better than you doesn't mean that she was perfect. She had many faults but in the end she was a kind and caring person which is more than I can say for you, you miserable hag."

Unable to stand being in the same room for a moment longer with the insufferable woman he apparated from the horrid house. He apparated into his home on Spinner's End and swept down into his potion's lab ignoring is mother's attempt to waylay him. She had remained her at Spinner's End even after his father finally drank himself into the grave despite his trying to convince her to move into a nicer place. He continued to spend his summers there to spend time with her and make sure that she was holding up well in the old mill town.

He began work on a complicated potion that required his full attention and forced all the rage from the conversation down. Hours later, once he was calmer. He rationalized that Petunia was a bitter, shrew of a woman so bored with her own dull life and so full of jealousy towards her prettier sister that she had created this scenario to amuse herself. He was determined to forget the whole thing. It was ridiculous and impossible and when he imagined that it might be true it left him with an ache so fierce he thought he might curl into a ball and never get up.

For a moment he even felt sorry for Potter having to live with the horrid woman and her rotund son and husband. It was obvious that Potter wasn't a spoiled child like he had assumed he would be. Maybe Potter wasn't all that bad after all not that he would ever admit it out loud. Petunia obviously hated the boy and if the lack of pictures in the living room was anything to go by it was obvious the boy hadn't had a loving childhood. Severus could sympathize.

He mentally shook himself. He would not sympathize with Potter! He would forget this ever happened and just try to enjoy the rest of his summer holiday.

oOoOo

Petunia was enraged by the nerve of Severus Snape but at least she had what she wanted. She wasted no time in sending out the samples from Severus and Harry to the facility she got the kit from. They said the results would take a couple of weeks but she was willingly to wait for the long-term results.

Vernon wasn't happy about spending the money for the test after having to buy the boy contacts but she explained that it meant they wouldn't have to deal with him in the future. He was more than happy to comply afterwards. So she waited, checking the mail every morning waiting anxiously for the package that would finally allow her to get rid of the nuisance of the boy. She had already perfected her speech to the neighbors about the discovery of the boy's father and how shocked she was by her sister's adulterous behavior. She could already imagine all the sympathy and attention she would garner from the story.

When the results finally arrived she was giddy as she opened the envelope with shaky fingers. As she scanned the results she felt a self-satisfied smile curl her lips.

"Vernon!" She cried and ran to show him the results.

He scanned them before allowing his own grin to stretch over his wide features.

"Get the boy, I'll get his trunk out of the cupboard," he said.

She went up to the boy's room and unlocked the door. The boy was sitting up on the small bed looking at her expectantly by the time she opened all the locks.

"Pack anything you want to keep in the next ten minutes because you're leaving and won't be coming back to this room," she snapped at him.

She didn't wait for his reaction she just marched into the next room to get to Dudley. She knew he would follow orders only because of the fact that she would never joke around about something like this. Dudley was put out but after explaining that this would mean he got his second room back he settled down.

"Aunt Petunia, I don't understand where are you taking me?" The boy questioned once they were all packed into the car.

"Shut up and don't pester your Aunt, boy!" Vernon snarled.

The boy glared but kept his mouth shut after that focusing his attention on his caged owl instead. The rest of the ride was done in silence except for Dudley's handheld game. They arrived at Spinner's End in good time and it made her sneer in triumph to see how much further the neighborhood had fallen since her childhood.

They pulled up to the crumbling old house and Vernon shouted, "Out boy!"

The boy glared but scrambled out of the car, clutching his owl cage tightly to him. Vernon got out to pull his trunk out of the boot and tossed it on to the yard. The front door of the house opened to reveal Eileen Snape. She was still just as thin and wane as ever but despite the wrinkles on her face she seemed more alive and robust than she had in Petunia's childhood; her silky black hair was even free of white despite her age. Of course that probably had something to do with the fact that her no good drunk of a husband was finally dead.

Petunia decided to go and speak with her. It seemed that Severus wasn't here at the moment and she wanted to be the one to tell her about her son's illegitimate child.

"Petunia Evans," she said by way of greeting her black eyes narrowing on her.

"Eileen, and it's Petunia Dursley now," she replied smugly.

"Well Mrs. Dursley to what do I owe the pleasure of this visit?" Eileen drawled softly.

"You see I've discovered something rather startling. It turns out that my nephew Harry, Lily's son, is not the son of James Potter. No Severus is the boy's biological father. I've had a paternity test done and it's come back positive. It's all right here in this envelope. We've already spent a lot of money on the boy and we shouldn't be the ones responsible for him when he has a father who is perfectly alive and well. We never wanted to deal with his freakishness and we've put up with a lot from him. But no more! He's not our problem anymore and you tell Severus he's lucky I'm not suing him for all the grievances we've had to put up with, with the boy," said Petunia glaring superciliously at the smaller woman.

"He may or may not be Severus' but I'll gladly take the boy Petunia because I feel sorry for any child that would have to spend even a second in your care. You were a miserable and horrible child Petunia Evans and you've grown into an even more horrible and miserable woman. Now get off my property," Eileen snapped back.

Shocked Petunia could only gape at the old woman's harsh words. She would have said something snide back but Vernon was honking the horn and thankfully she used that as an excuse to back out from under the searing gaze of Eileen Snape. She hadn't felt this terrified of Severus' black sneer a couple of weeks ago. But she had grown up with Severus. They had been children together whereas his mother had always terrified her due to the fact that she was the only adult witch she had known and she was always working on those creepy potions in the basement.

She quickly retreated to the car and climbed in. The boy was still standing beside the car looking stunned. The boy made a move to try and get back into the car but the door was locked and Vernon hit the gas and shot off down the road. Petunia had never felt so satisfied then in that moment to see the shocked and betrayed features of her sister's son in the rearview mirror as they drove off leaving all the freakishness of the wizarding world behind them.

oOoOo
