On 31st October 1981, an unwanted visitor entered Godrics Hallow, house of the Potters. The night was pierced by a shrill scream and a loud baby's wail. The house itself collapsed onto the ground with a loud 'Bang!'
Out of nowhere, a motorcycle flew towards the ruins of Godrics Hallow in the dead of the night. Rubeus Hagrid, 'Keeper of Keys and Grounds at Hogwarts', searched for the last surviving Potter in Great Britain, Alexis Rei Rose Potter soon to be called the Girl-Who-Lived.
He scurried among the ruins, scrying for the girl baby and other precious belongings that may be savored for her. She was hidden in the crib beneath a piece of plaster that hid her from the view of Hagrid.
At the sight of a familiar face, she stopped wailing and sobbed loudly.
"Mama! Dada!" she reached towards her fallen, lifeless mother. Watching Alexis reaching for the mother she will never have again made his heart hurt. Alexis will never know the love Lily and James had for her; she will not remember the taste of a mother's love and will never have a proper childhood.
"Dumbledore will know what is best for you" murmured Hagrid.
Her dark green eyes watched Hagrid curiously and astutely as he rummaged through his pockets, finally holding up the key for the flying motorcycle.
Hagrid arrived at number four Privet Drive, Little Whinging after four hours of driving. Little Alexis had been a pleasant traveling companion, sleeping non-stop for the whole of the ride.
"Ah…Alexis Rei Rose Potter, savior of the Wizarding World; in time, you will know why I have left you with your closest living relatives" murmured Albus Dumbledore; Headmaster of Hogwarts School of Witchcraft and Wizardry. Professor McGonagall had frantically tried to convince Professor Dumbledore not to leave the girl-who-live there with the Dursleys.
"It is the best place for her right now; she will grow up humble and kind to everybody. The wards that protects her even now relies on the blood protection"
Now, the Dursleys prided themselves on being the perfect family; epitome of the ordinary and normalcy. Therefore, it was surprising and shocking when Petunia Dursley came out to collect the delivered milk bottles in the morning and finding a thirteen months old baby on her doorstep, no less. She screamed at the sight of an eleven months old baby wrapped in a bundle of blue wool inside a crib on her doorstep. A letter rested on top of the baby.
Dear Petunia,
The baby you have found on your doorstep is your niece, Alexis Rei Rose Potter; the daughter of your deceased sister. Last night, Lily and James were murdered by the evil wizard, Lord Voldemort.
Alexis needs the protection of blood wards to ensure she survives to the age of eleven.
Your regards,
Albus Dumbledore (Headmaster of Hogwarts School of Witchcraft and Wizardry)
" Vernon? Vernon!" screeched Petunia.
"Yes, dear?"
"This girl, our niece, was found on our doorstep today" said Petunia adoringly, already in love with the little baby girl.
Vernon looked at the sleeping baby girl and back at his wife. Petunia's face was lit up the star on the top of a Christmas tree.
"Can we please keep her? You know I've wanted a daughter. She can be Dudley's sister" asked Petunia pleadingly with hope in her voice.
"Very well, it will be good for Dudley to have someone to play with. She can have Dudley's spare room" said Vernon, grudgingly
So on that day, because of the fact that Alexis was a girl and of Petunia's desire to have a daughter, the future of the Wizarding World had changed. Alexis Rei Rose Elora Potter became a part of the Dursley family; sister of Dudley, surrogate daughter of Petunia and Vernon Dursley. She was surrounded with love and care from her surrogate parents and brother.
Alexis grew up to be a very beautiful little girl even at the age of eleven with long red wavy hair and dark green eyes, a dead ringer for her late biological mother, Lily. Everybody who has met her loved her. However, it couldn't be said the same for Dudley. He acted the part of the protective older brother very well despite Alexis's protestations. Despite their young age, most of the boys at Surrey Primary already recognized the attraction of the opposite sex. The logic of boys under the age of thirteen was that the more pretty a girl is before puberty, the more beautiful she will be after puberty. So on that note, it is quite obvious to say that many boys are attracted to Alexis and demonstrate their 'coolness' in front of her by bashing up children younger than they are.
