The truth of how Severus Snape first met Olivia Abrams was not important, although the truth would involve the Potter Prat, Lucius Malfoy and and unfortunate hex on the poor girl. At the time Lucius had been a fifth year and Severus a third year, but the tears and fear in the wisp of a Slytherin first year had drawn both them to her aid. A quick disarming spell and well place itching spell had been very much appriciated during that first week of her term.
Liv, as it was soon discovered she prefered to be called, was an orphan living in Hogsmeade when she recived her letter and had been estatic at going to the large imposing school so many of her fellows went to. It was common knowlage the orphans where usually squibs or bastards of wealthy purebloods and Liv had wanted nothing more than to simply be an unwanted child having long been facinated by the magic she saw the Mistress doing around the small cabin where she lived with twelve other children. As her first year turned into her second and her second year into her third she blossomed under the watchful eyes of her guardians.
Lucius was the more brotherly of the two having grown up with solely his mourning father Abraxas after his mother's passing found her shy and dimmunitive posture to be a welcome change from the high pitch squealing of his intended's sisters. Bellatrix has only once come near the girl her sister's lover had adopted as a sister, and never forgot the deep loathing and pain Lucius cast onto her. Cissy for the wisp endearing and Liv brought out the maternal nurturing that Cissa always felt when she saw wounded birds or the like. She was pleased Lucius found someone else to watch over as she'd grown tired of the wizard, though lovingly doing so, scaring away any potential friends male or female.
Severus was a different story. He'd been dark and withdrawn all his life but the idea of the poor girl being harmed in anyway, especially but that dunce Potter, caused him to literally become violent and defensive. His fondest wish was for her to find happiness and remain as far away from any and all darkness, especially him. He'd once heard that the greatest thing one can do for someone they truly love is let them go, so unlike Lucius he encouraged the girl he'd affectionately come to view as a sister to date and find a nice Slytherin or Ravenclaw she fancied and marry him at their earliest convienience. Especially as his fifth year went on and he found his dreams of Lily morphing into dreams of Olivia.
As the year of Lucius' final year came to a close he was approched by the twinkling eyed headmaster and his own father and asked to perform the audacious task of spying on the Dark Lord. He agreed to do so only once the headmaster agreed to allow Olivia to be placed into his guardianship and Severus would be protected from the Mauraders.
I do not tell you this to give you a headache or to comfuse you. I tell you this because it is all things you must know if you wish to understand the love story of the dour Potions Professor and his Olivia.
