Lily gave him a second chance, they were together for a while however one night when Severus hadn't remembered to cover up his dark mark, they separated for good; Lily was 2 months pregnant with nowhere to go.

It was a cold and snowy Christmas eve when Lily Evans packed her bags and officially ended it with Severus Snape; he knew he's lost her long before she did, he also knew he'd have to let her go when he discovered she was pregnant; it wouldn't be safe for either of them, he had joined the Death Eaters before she took him back and could never leave them by choice. Leaving the house they bid each other a final goodbye as she walked out of his life forever. Unfortunately for the young, pregnant witch, she didn't have anywhere to go and without the ability to apparate safely due to the baby meaning she was trapped. Nevertheless she walked down the path for a few hours until early morning where she heard church bells; it was 6am on Christmas morning.

"Hello there dear, are you alright?" an old priest asked politely.

"I'm sorry to bother you sir, do you know if the church is open?" Lily asked politely avoiding his question.

"I'm sorry my child, Godrics Hollow church doesn't open for another hour, is there anything I can help you with?"

"Godrics Hollow? Do you know the Potters?" she asked curiously. She and James broke up when her father passed away to give her time to adjust, she's spoken to him briefly since but when she forgave Severus, even though James tried to understand, he couldn't, he was blinded by his hate.

"Of course my dear, it's that house on the corner. Are you friends with the young James Potter?" he asked.

"Yes, we went to school together"

"Are you that Lily he always talks about?" he asked a smile spreading across his face.

"I think I am" she replied smiling slightly, "Thank you"

"Anytime my dear" he replied before walking in to the church, which she noticed, was open.

Lily decided to visit James; if she were lucky he'd have a floo network so she could head home. As she knocked she felt butterflies in her stomach, when the door opened she came face to face to an older version of James, she knew it was his father but have never physically spoken to him.

"Good morning, I am terribly sorry to disturb you but I was wondering if James was home… or awake, I'm Lily Evans" she asked politely with a friendly smile.

"Of course he is, it's Christmas day, do come in. He'll be thrilled to see you. I feel like I already know you with the amount he talks about you, and to be honest those photos do not do you justice" Mr. Potter informed her as he lead her into the living room.

"Does James really talk about me that much?" Lily asked as an amused smile spread across her face.

"Yes" Mr. Potter replied simply before whispering, "Wait here."

Lily stood behind the door to where she presumed James was she listened to the conversation trying to contain her giggles.

"James, do you remember saying the only thing you want for Christmas is Lily Evans?" Mr. Potter asked loudly.

"Yes, but she's with Snivellus, and pregnant" James said defeated, obviously wondering why he's father is talking about Lily.

"Well, it's a Christmas miracle, I have cloned her and this is your copy" Mr. Potter pronounced seriously

Lily decided this was her cue and walked out acting robot like "Wow, Mr. James Potter, thank you for invited me into your lovely home, what nice parents you have, have, have…" Lily said each word with care and clarity ensuring to talk slowly and repeating the last word for effect.

"It's still a working product" he's father chuckled.

"There is no way you could clone someone, this is obviously…" James stopped himself realising it could only be the real thing: Lily. This is when he really looked at her, a full back pack on her back, a large bag in her hands, she was slightly shivering and her lips were slightly tinted blue, her hair was messy, she had bags under her eyes and above all, she looked like she might collapse in any moment.

"Lily, are you ok? What did Snape do?" he asked concerned.

"We broke up, he… he has the dark mark, you were right" she confessed.

After James had finally convinced her to relax and he got his house elf to take her things to one of the spare rooms, he removed his dressing gown from around him and wrapped it around her to try and warm her up.

After taking a warming potion and changing into clean and warm clothes, she accepted the invitation to stay at the Potters for Christmas, she took every opportunity to thank them and help out. She was all too grateful when Mrs. Potter provided her with potions that would help her during her pregnancy; it was unbelievable how kind they were when they hardly knew her.

Lily accepted the offer to stay the night and go home tomorrow, she was surprised to find that their house elf had already made up a spare bedroom, using beautiful silk sheets and she put away all of her belongings neatly into the wardrobe and draws, she also had her photos placed neatly on the bed side cabinet.

On boxing day Lily Evans was woken up to a loud bang followed by scrambling from downstairs, she slowly made her way down the Potters stairs into the living room where she saw James and Sirius wrestling for what seemed like the last pancake. She sat next to Remus whose eyes widened when he saw her there in her pyjamas

"Good morning Remus, are they fighting over the last pancake?" She asked quietly.

"Yes, what are you…" he didn't finish his sentence as Lily stood up and then walked in slightly loudly.

"Ooh last pancake, don't mind if I do," she pronounced loudly taking a bite of it only to watch both the boys freeze mid fight and stare at her.

"Oh you're going to wish you never touched that pancake, Evans!" James exclaimed whilst a cheeky smile spread across his face.

"And what are you going to do about it, Potter?" She asked with the same tone of voice. This caused James to slip out of Sirius now limp grip and chase her around the dinning room table and across the living room before she pulled Sirius between them using him as protection. At that exact moment Peter walked into the room having just been to the bathroom.

"Lily? What are you doing here?" he asked slightly happy but confused.

"I…err…well…" she started but couldn't think of how to explain she broke up with Severus of whom the majority didn't know she was dating and was pregnant with his child.

"I invited her, 1st Christmas out of Hogwarts wouldn't be the same without my Lily-pad" James butted in. Lily silently thanked James for covering up even if she didn't ask him to.

"Lily-pad?" Sirius, Remus, Lily and Peter all asked in confusion.

"No, not feeling that nickname? I have thought of hundreds"

"Stalker" Lily sang before retreating back upstairs to get dressed.

Lily ended up staying at the Potters and not going home at all… lets just say in that time her relationship with James increased…

June 21st 11pm Lily Evans water broke

3 hours later she was rewarded with a beautiful baby girl weighing 6 pounds 10 ounces with whom she named Tegan Lily Evans, which translates to 'beautiful and blessed' and 'Purity'. They also named Severus the Godfather out of respect and acknowledgement of his involvement in her life.

That day she was able to take Tegan home (to the Potters), as she was completely healthy. That evening Lily was shocked with what James had to say…

After sleeping for a few hours once back at the Potters, Lily came downstairs, fed her daughter and then saw candle light coming from outside. Mr. and Mrs. Potter offered to look after the infant allowing Lily to follow the light to find James in the garden holding a massive pink teddy bear with Tegan Lily sown across its belly.

"I thought you had grown out of teddy bears James" Lily commented revealing her presence to him.

"I brought it for Tegan, hence the name" he said pointing to its belly.

"It's very nice, though I'd keep it a distance from the candle light" she joked as he indicated for her to take a seat.

After 30 minutes of a delicious meal made by James (beans on toast), James knelt down in front of an unexpected Lily

"Lily Evans, I have been in love with you since the first time I laid my eyes on you. I would like to be married to you and become a family with you and little Tegan. Will you marry me?" he asked throwing away most of his prepared speech due to nerves. He opened the red velvet box and waited for an answer, although he didn't expect the answer to come as quick as it did.

"Of course I will!" Lily breathed falling forwards to hug him before leaning back enough for their lips to connect.

They couldn't however enjoy the moment for long as Mr. and Mrs. Potter ran out (holding Tegan) to hug them.

A month and a half later on August 11th they had a small and loud wedding held at Godrics Hollow Church, it was initially going to be held on August 7th until they discovered it was a full moon and changed it giving Remus enough time to recover.

After the beautiful ceremony, Mr. and Mrs. Potter announced they are giving full ownership of the house to James and Lily as they have brought a small cottage to spend the rest of their lives in.

After James and Lily got married they changed Tegan's name to Tegan Lily Potter.

On 23rd of June Severus Snape received a letter with a photograph of a newborn child attached, the letter read:

Dear Severus Snape,

This is your daughter, Tegan Lily Evans; she was born on 22nd June at 2am weighing 6 pounds 10 ounces . I'll keep you updated on her progress. You have been named Godfather as well as Father

Sincerely,

James Potter

Severus Snape was extremely shocked that James was the one who sent the letter and offered to send information about his child but very thankful.

Over the course of three years he had received letters about Tegan from James.

Dear Severus Snape,

I shall ensure Tegan receives your Christmas presents. I ask if you would send a picture of yourself in order for her to know your face ~ Lily refuses for you to see her so unfortunately you won't be able to personally see her for Christmas.

Also her last name as been changed to Potter due to Lily and I getting married

Sincerely,

James Potter

Dear Severus Snape,

Attached are two pictures, Tegan's first Christmas morning and Tegan wearing one of the beautiful dresses you brought her. The photograph you sent has been framed and hung on her wall .

Sincerely,

James Potter

Dear Severus Snape,

Lily still refuses for you to see Tegan; I'm sorry.

New photo attached; aged 9 and a half months

Sincerely,

James Potter

Dear Severus Snape,

Sincerely,

James Potter

Dear Severus Snape ,

Attached are a selection of photos of Tegan from her birthday up till the end of new years ~ she loved her magical dancing professor

Sincerely,

James Potter

Dear Severus Snape,

Due to Lily's pregnancy Hormones, she has allowed you to visit Tegan tomorrow, come Godrics Hollow Church for 9am to spend some time and finally see Tegan

Sincerely,

James Potter

After Severus had met is daughter, she was all he could think about, unfortunately he couldn't do anything. On that day he asked James why he was sending him photos; the response he got was 'Everybody has the right to know about their children and parents.'

He was able to see Tegan a further 3 times before a certain night, it was the night he refused to talk about, the night where his alleged master killed his only love, Halloween; he never saw Lily and wasn't sure if she actually knew about him seeing Tegan.

31st October 1981, Halloween, Tegan age 3 and a quarter heard a bang downstairs and jumped out of her bed and wandered towards the door to investigate, as she opened the door and she saw her mother enter her little brother Harry's room. As Tegan entered the room she bumped into her mother who was exiting the room.

"Tegan, you need to hide, quickly," her mother gasped out. Lily led her under the changing table and pointing her wand towards her as she mumbled a spell.

"Don't say anything, wait until someone tells you to come out, someone you trust, just be brave"

Tegan remained quiet a curled into a ball closer to the wall due to her Mummy's scared expression, she half thought it might be a game but heard another explosion downstairs and began crying out of fear. Her young eyes watched as her mother pointed her wand at her brother only to have it blown out of her hands by a man in the doorway before she could complete it. She watched as the man pointed his wand at her Mummy and made a bright green light hit her causing her to fall to the ground seemingly asleep, she watched as the man turned to her little brother and repeated the process however Harry didn't go to sleep, the man disappeared shouting loudly making more tears run down the young girls face.

She waited there for a long time but nobody came, just as the girl picked up the courage to wake up her mum she heard a noise down stairs and quickly hid under the changing table again. She watched as another man wearing black walked in and held her mother, she remembered him from church, her dad occasionally took her there to see her other dad. And here he was; he must be whom Mum meant.

"Dad?" Tegan asked timidly still curled up.

"Hello?" her father asked taking his wand out.

"I'm here," she said edging out from her hiding place.

When he couldn't see her, he guess her position and preformed a revealing spell, he saw his daughter with tear stained cheeks and puffy eyes looking at him, she was wearing pink pyjamas and was cuddling a small teddy bear; when he looked closer he realised it was the teddy bear he sent when she was born.

"Are you hurt?" Severus asked gently moving towards the young girl. He attempted to keep his emotions in order for the benefit of his daughter

"Can we wake Mummy up now, the sun is coming back up" she asked innocently not completely understanding what happened.

"She can't wake up, she… she has gone to heaven" he told her.

"But she's right there, she's not gone anywhere, we just need to wake her" she informed him. She walked over to her mum and began shaking her "Mum, mummy, time to wake up… Mummy, Mum, wakey, wakey… Mum… Mummy… wake up" she began crying as she realised her mum wasn't waking up, she kept saying 'mummy' repeatedly as Severus took the crying bundle into his arms and gently shook her.

When Severus turned around he saw members of the Auror and Order standing their staring at the scene and him, all wands were pointed at him.

"Let the child go!" Moody ordered, Severus reluctantly indicated for someone to come and get her, as soon as someone else touched Tegan she began screaming and gripped on to Severus for dear life.

"Let Tegan go!" Remus Lupin shouted as he ran into the room, momentarily freezing upon seeing another one of his friends lying dead on the floor "He's her father" he announced to them all causing a lot of gasps.

Tegan looked a split image of her mother except her black hair and black eyes, nobody even asked questions where they came from, but knowing Snape was the father the could clearly see the resemblance between them.

"He has also been named the Godfather so as, Lily and James are … he's to look after her and Sirius Black to look after Harry" Lupin explained keeping his head up trying not to look at the dead body of Lily, he could keep it together until he got home.

"There is one problem with that" Moody informed us "Sirius Black is the one that betrayed them. He killed a lot of muggles and Peter Pettigrew as well in order to get away. He was trying to help kill the boy."

"What?" Remus asked not bothering to hide his shock or betrayal.

"Straight to Azkaban when we find him, somebody go get Dumbledore, he'll know what to do" Moody ordered walking out of the room.

"Are you going to wake up Mummy?" Tegan asked the Order who instantly began to tear up.

"I'm sorry but we can't" one of them said.

"No you have to! Who's going to make me breakfast?" she asked in between sobs "I'm too little to use the toaster."

Nobody could answer her, as nobody could think of what to say; she wouldn't understand.

Dumbledore arrived moments later with a solemn expression on his face, he was shocked to see members of the Order allowing Snape to hold Lily and James' daughter but did not question it as he examined the scene.

"Does anybody know the specifics of what happened here?" he asked everybody.

"Both parents are dead, the boy's head as been cleared up, he's been cut" one of the Aurors informed him

"Dead?" Tegan asked "Is that what the green light did?"

"Have any of you questioned the child?" Dumbledore asked looking at her.

"Why would someone want to dead my mum and dad?" Tegan asked.

"Actually they wanted to 'dead' your little brother," Moody told her receiving glares from nearly everybody in the room.

"He used the green light at Harry too, Harry is not dead"

"Excuse me?" Dumbledore's eyes widened "I am going to look into your mind, is that ok?"

Tegan nodded and looked at the old man straight at his twinkling blue eyes.

Dumbledore entered her mind and told her to remember that night, the first vision he saw was green followed by Lily lying on the floor, then their was another green flash and Voldemort was destroyed leaving Harry with blood running down his face, he asked her to think about what next happened and saw Snape to walk in the room and when he did the room lightened, when he saw Snape he received flashes of him with Tegan inside a church before returning back to the room where Tegan called him dad and tried to wake up her Mum before allowing Snape to hug her. Dumbledore left her mind with a slightly shocked expression

"It seems little Harry survived the killing curse and defeated Lord Voldemort"

A few days later it had decided that Tegan would be under the custody of her biological father Snape and Harry would be under the custody of his biological Aunt, Petunia; Snape had offered to look after and raise Harry as well but was refused, he wanted to some how repay James unexpected kindness.

Snape returned to work as a professor at Hogwarts after a week of absents, much to the disappointment of all the students. Dumbledore had magically extended Snape's room and created an extra room that was connected to his classroom in order to be able to look after the young child 24/7.

The students found it strange when they first discovered Snape had a daughter (her name was now Tegan Lily Snape) but the resemblance was impeccable with black hair and black eyes. Snape usually was able to find another teacher who wasn't teaching to look after Tegan while he was teaching but it had not always been possible. In the end he had changed the spare room in his classroom into a play room for her, teachers and students donated toys for her, Tegan spent most of her time in the room playing or drawing.

It was a week before Christmas holidays were due to start when Tegan exited her play room without permission; she tugged on the first persons robes she came up to. A first year boy with ginger hair bent down to her level, "Hello" he said.

"I'm cold, I want my daddy," she moaned.

"Awe, well your Daddy is dealing with a crisis, someone blew their cauldron up, again."

"I'm really cold," she moaned again as tears began running down her face rapidly.

"Shh, don't cry" he soothed as he felt her arms which were hot, he then felt her forehead which was hotter "You're burning up!" he exclaimed picking up the child.

"No, I'm cold" she moaned crying into his shoulder.

The ginger first year managed to hold her but with a little difficulty, he walked closer to his least favourite professor, "Professor Snape, sir?"

"Hold on"

"Professor Snape, I need…"

"I'm busy, Weasley" the professor said sternly as he magically continued clearing up the mess.

"But Professor, your daughter has a fever"

Professor Snape instantly turned around to see Bill Weasley holding his crying daughter.

"What?" he asked in disbelief. He obviously didn't believe the first year student.

"She says she cold but is really hot" Bill explains slightly scared.

"Class dismissed," announced Snape. He took Tegan into his arms and instantly began walking towards the infirmary to see if Madam Pomfrey can help. It was just the flu; Bill was awarded 5 points.

Throughout the years, Snape still remained the most feared and hated teacher, Tegan acted more like him but kept the gold heart she'd inherited from her mother and never managed to say a mean word towards or about anybody, however she became an expert at glaring. Snape had constantly used his daughter to show students how easy a potion could be made since she was 7 years old. She enjoyed making potions because it made her Dad proud of her but yeaned the opportunity to do more magic; she was mostly looking forward to charms and the levitation charm she has heard so much about. She was counting down the days until she could attend Hogwarts as a student and not as a teacher's child.

Tegan, aged 9, approached her father on Christmas Eve; they'd decided to stay at Hogwarts instead of going home,

"Dad, can I ask you a question?" she asked sitting down next to him as he was grading papers.

"Of course" he breathed only half paying attention to her.

"Everybody presumes I'm going to be in Slytherin, would you disown me or be disappointed if I'm not in Slytherin?" she asked serious, fearing the response.

"Your mother was in Gryffindor," he informed her.

"That doesn't answer my question"

"Why wouldn't you be in Slytherin?" he asked.

"Well you're a half-blood and my Mum was a muggleborn, that makes me really far from being a pureblood. I'm not gifted in potions or anything like that like you were, surely I'm not eligible to be part of Slytherin," she told him her reasoning for the question.

"That is a possibly conclusion… I could never disown you, you are my daughter and I will love you regardless" he commented, finally looking at her so she knows he loves her and would never disown her, ever.

"But would you be disappointed if I'm not worthy enough to be in Slytherin?" she pressed the matter at hand.

"It is not about one being worthy," he informed her; he knew this conversation wouldn't be over soon.

"It is because only purebloods can usually get into Slytherin, the other houses don't have any special recommendations"

"Yes they do, Hufflepuff's must be loyal and hardworking to be placed within that house. Ravenclaw's are smart and eager to learn. Gryffindor's are courageous and not afraid to face their fears. Slytherins are cunning, ambitious and yes usually pureblood. Each is magnificent in its own way, also everybody usually has a little of each house inside them."

"So Slytherin isn't that special?" she asked.

"No…" he replied carefully.

"So it doesn't matter which house I'm in?" she asked, still concerned about the situation.

"As long as you are happy, but do remember even if you are in a different house, you'll always be my favourite student."

Tegan laughed "Ok, Dad."

"Well, you should go to bed, Christmas tomorrow" he informed her.

"I'm going, I'm going," she repeated running into her room to get changed.

Later that year during one of Snape's lessons, Tegan snuck into it to talk to Charlie about a dragon she had recently heard about. She successfully got past her dad who was grading some papers and to his desk unnoticed by anybody.

"Charlie" she whispered gaining his attention from his potions partner.

"Hello Tegan, what interesting dragon have you heard about this time?" He asked amused.

"The Hungarian Horntail, I heard it was feisty," she informed him.

"Ooh, the Hungarian Horntail, yes that is an interesting one, well…" Charlie went on to tell Tegan all about her selected dragon for 10 minutes until his partner finally got his attention.

"Charlie, is the potion suppose to bubble that colour?" his partner explained indicating to the red solution bubbling over the cauldron.

"I thought it was supposed to be purple?" Charlie asked out loud.

"You just need more Alihosty, it's this plant, it will balance it out" Tegan informed them climbing on a stall and adding the plant, the potion began turning purple, Tegan then began mixing it clockwise, soon it stopped bubbling over and looked almost complete.

"Now you just need 2 beetle eyes and it should be complete," she informed them/

"Oh thanks" Charlie thanked her adding the last ingredient and stirring the potion, it turned bright purple meaning it has been completely correctly.

"Yes, we did it!" his partner shouted attaining the attention of Professor Snape who noticed his daughter among the 5th year class.

"Do you mean my 9 year old daughter did it?" he asked slightly amused "10 points from Gryffindor for trying to take credit from someone else."

"That's not fair she's the one that distracted Charlie," he complained.

"10 points from Gryffindor for blaming my daughter" he sneered at him before turning to his daughter "What have I told you about sneaking into my classes?"

"It could be dangerous" she recited "Sorry."

"That's OK, now step away from the cauldrons and come over here," Snape ordered.

Tegan walked over to her Dad and sat in his seat while he stood up to examine the potions made.

"We're sorry too Professor Snape" Charlie's partner said as Snape approached.

"No, leave me out of this" Charlie quickly said holding his hands up in surrender.

"Detention, both of you tonight 7pm. don't. Be. Late. Class Dismissed."

The whole class quickly exited the classroom; Charlie looked over at Tegan and mouthed that they would talk later.

"Why do you always talk to that Weasley?" Snape asked her once the classroom had emptied.

"He tells me about Dragons, I find it interesting" she confessed.

"I don't want to see you sneaking into any more of my classes until you attend Hogwarts at 11, do you understand?"

"Yes" she replied looking down at her feet.

"Yes what?"

"Yes Sir"
