The remainder of the school year had gone by without a hitch. Nobody had ever suspected anything about the relationship that had remained under wraps between the Potions Master in Residence and the Gryffindor Princess herself, Hermione Granger.
Everything had stuck to the status quo, until Granger did something that nobody ever expected her to do. She apprenticed herself to none other than her former head of house, Professor McGonagall. The Professor had expressed her desire to retire from her teaching post to help the headmaster as duty of deputy headmistress.
Everybody had believed that Hermione would peruse a career with the Ministry of Magic, though those who claimed to be her friends knew that she had never even considered a position at the severely corrupt firm.
Nobody noticed anything strange until the honorary eighth year's graduation. Hermione had taken a long time in preparing herself for the ceremony.
As the valedictorian of her smaller class, she was the last one to get her diploma. What stunned the well wishing on lookers the most was that the young war heroine who was graduating from the strong and proud Gryffindor house was wearing Slytherin colors... and a wedding band?
One could have heard a fly's footfall in the Great Hall as Hermione skipped her way across the dais, receiving her diploma and a warm, fatherly hug from the Headmaster himself, and then going down the row of teachers shaking their hands. The second to last teacher in the row was McGonagall, whom Hermione also gave a warm hug to, and promised that her first class syllabus for next year would be in her hand by early next week.
What happened with Hermione and the final teacher was what gave the audience a run for their money.
"Severus!" Hermione cried as she launched herself into his arms.
"Love, do be careful, I do not want you to injure yourself flinging yourself carelessly at me." If the audience's jaws weren't literally on the floor already, what happened next made sure that they were.
Hermione Jean Granger, the one and only Princess of Gryffindor began to snog her Potions Professor, a Severus Tobias Snape, former Death Eater, member of the Order of the Phoenix, and resident Dungeon Bat/Vampire, soundly on the mouth.
The audience was broken out of their trance when they came to the realization that not only were the two wearing matching wedding bands, but that the rest of the staff was laughing.
"Oh, Severus!" The Headmaster chortled, "We were wondering how long it would take for you to, Dear Merlin, figure out that she was perfect for you, and vice versa!"
Still cradling his wife, Severus turned towards the rest of the staff, "Well than why didn't you bloody tell me? Was it so damned obvious that the castle itself had to step in and do something about it?"
"Oh, Sev," McGonagall started, "Who said it was just the castle who had something to do with it?" She had tears streaming down her face because she was laughing so hard.
"We were all wondering how the two of you would announce all this!" Pomona Sprout giggled from where she was standing, clutching her stomach from laughing so hard.
Hermione stopped and turned to Severus, exchanging a questioning glance with him. Whatever the question was, he understood it and nodded his ascent.
"In that case, I suppose that Severus and I have another announcement we would like to share with you all," She gazed nervously over the audience from her protected spot in Severus Snape's arms. "Severus and I have decided to start our family." The audience gasped. "These two," she continued, waving her hand over her abdomen, releasing a disillusionment spell which revealed her swollen belly, "are due in a little over six months!" Severus proudly wrapped his arms around his young wife.
If the previous announcement hadn't been a surprise to the people in the room, this one most definitely was. Even the professors were dumbstruck by this one.
McGonagall was the first one to break the silence. "Hermione! Why didn't you tell me!? Oh, it will be so great to have little ones running around the castle again! Right, Albus? Oh! I can't wait!" She ran over and gave two of her favourite former students a huge hug.
"Thank you, Minerva," Snape said, "You don't know how much it means to us both."
They turned to look at Dumbledore who had tears in his eyes, "Those are some very powerful and dreadfully smart children you are carrying Hermione, my dearest. They will do great things, both for the wizarding world, and our beloved school. Severus you should be very, very proud." He came over, shook Severus' hand and gave Hermione another fatherly hug. "Now, if you will all excuse me, I must to find a new supplier of woolen infant socks, I have not needed to purchase a pair for Christmas for quite a while! How thrilling!" And with that, the headmaster skipped off the dais, wiping the last remaining tears from his twinkling eyes that were absolutely brimming with mischief with a yellow and purple polka-dot embroidered handkerchief.
