Yes, I do know that in the books and films Tonks is five years older than Harry. I have said on multiple occasions that in this story Tonks in the same age as James, Remus, and Sirius. This has been said in the comments many times, Please, I know how it works in the films and books, but this is my work.
Again, I don't own Harry Potter, which remains to J.K Rowling.

Hermione, Emily, Sophia, Draco, Ron, Harry, and Lee watched crying with laughter as the twins forced Percy's Weasley jumper over his head and each marched him down to breakfast, the rest of group followed, still crying with laughter, each were wearing their Weasley jumpers, the twins seemed to be barking orders at Percy about what he was and wasn't allowed to do during Christmas Day. The group caught up and they all headed into the Great Hall for breakfast, upon arriving they saw a lot of mistletoe hanging from the ceiling and they all made it their personal mission to try and avoid getting stuck under the stuff. It was more than obvious that many people hadn't got the message to avoid it and were stuck under the mistletoe with no-one to kiss them.

They all sat down to a large breakfast before going out wrapped up warm to have a snowball fight and, much to Emily's happiness, it was still snowing very heavily. Those who had remained at the school for Christmas, including teachers, started a large snowball fight, and it was everyone for themselves. By the end of the fight, everyone was shivering except for Emily and Draco who had teamed up and built a fort near enough to the Whomping Willow so they weren't getting hit but no-one could sneak up behind them. This resulted in them having a lot of people running head on at them, the twins had jinxed a lot of large snowballs to constantly hit the back of Professor Quirrell's head.

After the hour-long snowball fight, Professor Dumbledore announced Emily and Draco the winners and told everyone to go and get a hot chocolate before getting changed, in the Gryffindor common room they had Harry's new record player playing a number of Muggle records like Adam and the Ants and Big Country. They were all dancing to Where The Rose Is Sown by Big Country while they were dripping from the now-melted snow on their clothes, even Percy was laughing, everyone was joking about and finally went to get changed just as the song came to an end, they removed the needle from the record. In the third year boys dorm, they all showered and changed before heading down to lunch, Emily was wearing her favourite jumper that the twins gave her in her first year, it was an Alice in Wonderland jumper that said 'We're All Mad Here' with the Cheshire Cat's grin, she loved it because the twins didn't understand Muggle sizes so got her a large one.

As they arrived in the Great Hall, George had his arm wrapped around Emily's waist, Fred held Hermione's hand, and Draco was holding Sophia's, they had forgotten about all the mistletoe, that was until George got stuck under some, Percy found this quite amusing thinking that the others would all laugh, the entire hall seemed to be looking, their eyes all gleaming with anticipation as Fred said "trust you," with an evil grin. Then without any warning, Emily just kissed him and the group carried on like nothing happened. George's arm snaked back around Emily's waist and he pulled her close,
"I guess that we aren't keeping it a secret any longer then?"
Emily shook her head lightly before smiling and kissing his cheek lightly. The entire hall, including the teachers, looked at them, all shocked. Money was suddenly being passed through the entire hall and Emily laughed when she saw Snape handing McGonagall 2 Galleons.

The group sat down to eat their lunch gaining funny looks as George still held Emily's hand until they were all sat down at the table with Percy, Draco, Harry, Lee and Sophia on one side and Emily, George, Fred, Hermione, and Ron on the other. They began to eat and joke with each other and then Draco began to blush profusely when Emily slipped up while speaking,
"C'mon Snowflake, did you really expect Lucius and Narcissa to send you anything?" Emily didn't realize what she said but they all looked at her confused and Draco tried to hide his face while Harry was trying to stifle a laugh. Draco then tried to pull his jumper over his bracelet so that the others wouldn't see it. But before he hid it successfully Sophia grabbed his wrist and looked at the bracelet, she looked at it and then to Draco and lastly to Emily and Harry, both were still laughing very heavily. And that seemed it, the group carried on calling Draco 'Snowflake.' After lunch in the third year boy's dorm, they all began talking about nicknames,
"Well I'm Ice-Eye," Emily said and they all agreed even though the twins and Lee had been calling her that since they met. Harry then looked up
"I've been 'Flight' ever since I completed training to be a..." He faded off realizing what he had said and slowly looked at Emily. Hermione, Sophia, and Ron looked at her and George took her shaking hand as she spoke slowly, picking her words very carefully,
"When I was born, I was different, special if you will. Anyway, well I... I'm- I'm a werewolf." The last word was said barely above a whisper but in the silence of the room, the group heard her, Ron backed away and Emily looked down, ashamed. Hermione looked at her and then spoke,
"Last month, I saw a werewolf and two Winter Wolves running at the edge of the Forbidden Forest. Was that you guys?"
Emily, Fred and George all looked at each other and then back to Hermione, Ron hadn't stopped looking suspiciously at Emily who decided to end the tension,
"C'mon lets go to the common room for a bit, join in with the others."

They entered the common room where everyone else was talking when Ron said,
"Is that why Percy hated you for ages?" He glared daggers at Emily's back as Oliver Wood stormed over muttering about Angelina Johnson leaving the Quidditch team at the very start of season,
"Emily, my lovely Emily, my sweet sweet loving caring Emily," he was getting glared at but it was all in good nature, "do you know anyone who would be good on the Quidditch team as a chaser, if not we forfeit the cup, do you know anyone to be your right hand, please?" He looked at Emily as all those around looked at Hermione and Emily just smiled and turned.
"Oh sweet Hermione, I need a favour." Hermione agreed, she wasn't that confident on a broom but they would all help her out in the practice.

Ron had stopped liking Emily and was constantly making snide remarks about her being a werewolf, none of the others were bothered by it but Ron was. Hermione had noticed that the Prowl was led by Emily but she seemed to be guarded by the boys and no-one was allowed near her if the twins didn't like the look of that person. No-one other than George had noticed how badly Ron's comments were affecting Emily it was making her spiral downward into the state she was at when she first started at Hogwarts, it had taken her until Christmas before she was speaking even simple sentences and she wasn't fully speaking until the start of her second year.

Next chapter will be up soon, Thank you for the continued support.
Sorry this has taken me so long to update but one of my friends is in a difficult place and I'm beginning to question myself about things ;)
