"Don't be a baby" nine year old Morticia Snape raised the heavy long bow with surprising ease and carefully took aim, "I know what I'm doing"
Eleven year old Severus Snape crossed his arms tightly across his chest and cast his eyes up at the rosy red apple perched atop his raven locks. "Aim a little higher" he guided her. With slow skill Morticia closed one eye and released the arrow, sending it flying through the air in into the core of the apple. Severus calmly stepped away with the Apple hovering where his head was, pinned to the large tree where He and his younger sister hide out during the day.
"Freak!" The siblings turned their heads sharply and peered out from behind the tree. Two girls stood a few yards away, one looked about Severus's age and one looked a few years older, "You're a freak Lily!" the older girl yelled as the younger girl, dubbed Lily, fled to the tree, "Get back here! I'm telling Mummy! You're a Freak!"
Morticia stepped out from behind the tree, the older girl took one look at the skinny, ghost like girl with long black hair and crisp black dress and stumbled back. "Hello." Morticia greeted, pulling Severus from behind the tree, "What's your name?" she asked politely. "Lily." The girl replied, tears rimmed her eyes.
"I'm Morticia," she nodded, "And this." She turned to Severus and pulled him from behind the tree once more, "Is my big brother, Severus." Severus waved shyly.
Morticia took note of the older girl's distress and plucked a clover up from the ground and placing it in the palm of her hand. Slowly the white spherical flower shuttered and sighed, before sprouting tiny white wings and fluttering toward the ginger girl, gently landing on her nose.
Lily giggled, "You can do it to!" she cheered joyously, "That girl is wrong, you're not a freak." Severus finally spoke up, Lily looked behind her where her sister once was, "That was my older sister, Petunia" Lily shrugged.
Two hours later, the three of them sat by the shallow pond in the shade of a tree, Severus laying on his back, silently making the seeds that fell from the tree fly through the air so they wouldn't hit the children sitting below. Lily sat behind Morticia, whom she had taken to calling Tish, braiding the younger girl's inky black hair into two long braids.
"She's just jealous, because she's ordinary and you're special." Severus insisted, "That's mean Severus." Lily scolded him. "But true." Morticia nodded as Lily tied the ends of the two braids together with a rubber band. "Are you going to Hogwarts this year?" Severus asked hopefully, "Yes I just got the letter this morning" Lily said with a spark of ecstasy.
"I didn't even know magic was real until this morning!" Morticia and Severus looked at each other and said in unison, "MuggleBorn."
"What's a Muggle?" Lily asked, "Non Magic folk. Like your sister." Severus explained. "Some families with all magic members, feel that they're better than others because they're Pureblood."
"That's horrid." Lily gasped, Morticia nodded. The Sun began to set over the horizon and the night grew chilly. Severus fetched several small stones from the lining of the pond and piled them in a medium sized circle. Morticia slid her fingers quickly down the side of the tree, setting the tips of her fingers aflame. Lily watched, mouth agape as Tish lit the small fire then blew out her fingers, leaving no trace of any injury.
"Could you teach me that?" Lily asked, Morticia smiled, "Old family secrets."
Two years Later, Morticia would join her friends at Hogwarts.
(Time skip)
Professor McGonagall read from the long scroll before her, "Snape, Morticia" She called. The petite, raven haired girl primly placed herself upon the stool, McGonagall placed the heavy hat on Morticia's braids.
"Hmmmm, let's see, let's see, another Snape. Much more morbid that your brother, but intelligent and kind hearted. Better be…."
"RAVENCLAW"
Severus was slightly disappointed that Tish wasn't placed in Slytherin, but Clapped as his younger sister made her way to the Ravenclaw table. Meanwhile, Lily, whooped and clapped for her friend. Morticia did quite well in Ravenclaw. Her favorite subject we Herbology, however she was often scolded by Professor Sprout for cutting of the blooms from the flowers she was assigned to care for.
Seven years later.
Morticia disembarked the Hogwarts express for the last time. Severus waited for her, By Morticia's first car, a used black Hurst. Purchased the past summer, Severus next learnt to drive and thought it was a useless skill. "So." He grinned As Morticia approached in her skin tight black dress, "Terribly Unhappy." Morticia sighed blissfully, "Good." Her brother nodded.
"Cara Mia!" Morticia turned and was lifted into the air by a pair of strong arms. "Gomez!" she breathed as he spun her. "Uh, excuse me." Severus cut in, "Explanations please"
"Oh, Severus." Morticia Smiled, "This is Gomez Addams, my boyfriend."
"Uh Huh, and how long has this been going on exactly." The elder brother asked, surprised that his sister hadn't bothered to mention this boyfriend, not that she hadn't had any before, but this was the first she hadn't told him about.
"Oh, only a few months." Gomez sighed, "Four bliss filled months"
"Uh huh." Severus pressed his tongue to his bottom lip, "Oh Severus please don't be mad, I've been meaning to tell you, but with the….." she cut off, not wanting to mention the Deatheaters. Morbid, Sadistic, and gruesome she maybe, but Racism was one thing that Morticia Snape would not stand for. After Severus joined the group Morticia wouldn't even look at him. Until he told her that he had become a double agent, she had practically disowned him.
"How about, you and Gomez get to know each other." Morticia offered, "Capital Idea Tish!" Gomez agreed, "How about it old man?"
Severus blinked for a moment, and processed what just happened, "Uh, okay." He said slowly, secretly wondering what the hell he just got in to.
One year later
"Severus, you'll never guess what's happened!" Morticia took tiny steps in her tight black dress, rushing toward Her brother who sat reading the Daily Prophet. "So help me God, if you dragged in another man eating Plant." Severus warned.
"Oh don't be silly, and Look!" Morticia held out her left hand as she was tailed by Gomez who was sucking on a thick cigar. Severus glanced over the paper and nearly dropped his jaw at the sight of the large diamond ring on Tish's finger.
"Isn't it just wonderful? Gomez asked me to marry him." She explained, "And we'd like you're blessing."
Severus glanced at the odd couple before him, after a few moments he sighed, "You love my sister?" he asked Gomez, "More than anything." Severus glanced at Morticia, "And you love him?" Morticia nodded and held Gomez's large rough hand in her own small, silken one.
"Very well." The elder brother nodded with a sighed, "I now pronounce you Fruit Basket and Nut case."
To Severus's shock, Gomez enveloped him in a bone crushing hug, "Gomez, Gomez, remember what I said about boundaries?"
"Right sorry" Gomez said insincerely, taking another puff from his cigar.
Gomez and Morticia were married that Halloween, every member of Gomez's extremely large family gathered in the Addams family cemetery for the service along with Morticia's closest friends. A large Grave served as the alter and Morticia's dress was Black silk and Lace.
Lily nearly had a heart attack when she saw it be smiled and nodded all the same.
"Here, on the remains of Addams families past, we join our Brother, Gomez Addams and Morticia Snape in Unholy Matrimony." The eldest member of the Addams family, Gomez's great great aunt Calpurnia announced. "Morticia Snape, do you swear to uphold the traditions of the Addams Clan? To Love and Cherish your husband for as long as you both shall live, and after?"
"I do."
"And Gomez Addams, do you Swear to uphold the traditions of the Addams Clan? To love and Cherish your wife for as long as you both shall live, and after?"
"I do."
"Then by the power vested in me by the souls of the dearly departed, I now pronounce you man and wife."
Nine years later
The night was stormy and cold in a little Massachusetts town. On the top of the highest hill in town was an old museum that now acted at the Addams's house. Severus Held a large black Umbrella over his head as rain fell in waves
