Nineteen Years Later.
Severus casually walked through the stone barrier, clutching a tiny hand in one hand and a walking stick in the other. He stepped onto platform 9 and ¾ and took in his surroundings. The platform was far too overcrowded for Severus' liking. A few number of witches and wizards gazed at Severus with awe or disdain, not that Severus' noticed or cared about what people thought of him.
There was still 30 minutes until the train was scheduled to leave, Hermione insisted that they arrive plenty early to allow Eileen enough time to put her luggage onto the train and say proper goodbyes. Personally, Severus didn't see why they had arrive so early, he just agreed to it because it wasn't worth discussing with Hermione. She would end up having it her way anyway, so why bother fighting over it.
"Daddy, hurry up! I don't want to miss the train!" The young witch holding her father's hand told him resolutely. Eileen looked like her father: Long black hair, black eyes, the only thing that she didn't have, which Severus was thankful for, was that her nose resembled didn't resemble his. Severus didn't understand, but Hermione loved his nose.
"Well, Severus, you heard the young lady, let's get going." Hermione came strolling up beside them, clutching Eileen's trolley in her hand and smiled at her husband and daughter.
"Ginny, Merlin's sakes, let him be." Hermione looked through the crowd and saw Ginny kneeling down, cleaning her son's face and Harry standing nearby, holding his daughter's hand.
"His face is dirty, Harry, I just cleaned it before we left." Ginny sighed, getting up and noticing Hermione and Professor Snape, she waved over to them. Hermione happily walked over, while Severus first acted like he didn't see them, but slowly, reluctantly walked over after Eileen basically pulled him towards them. The two young witches embraced.
"So, Hermione, are you nervous about going back to Hogwarts?" Ginny asked.
"Yes, Aberforth will be overshadowing me for my first few weeks until I'm good and ready." Hermione smiled. She was both thrilled and nervous about teaching. But both Minerva and Aberforth agreed she will be best suited to take over as Transfiguration Professor and Head of Gryffindor house.
"Dad, Dad!" Harry's son was shaking his father's hand wanting his attention, "We're going to be late!"
"Severus Potter! We will be ready shortly." Harry said to his son. Severus hated that Harry named his son after him, Severus would never even name his own son after himself. Growing up is challenging enough without the stigma of what a name carries. They'd run the risk of their son being seriously taunted and abused, he made his case know to them but they were set for it.
"Severus, will you please go easy on the students," Ginny pleaded, "James said you overworked him and his class last year."
"Mum, I didn't say that!" James, who was standing beside his father, was red with embarrassment.
"James was in fourth year. If he is unable to perform and finish the assigned work, than he will find that this year will be even harder." Severus glanced at James, "The Dark Arts is not a subject to be taking lightly." Since the Dark Lord's death, the curse placed upon the Dark Arts job was removed and Severus was teaching the subject for the past five years. He only agreed to take the job if Minerva, the current Headmistress, agreed to allow him to set up the floo network to his office so he could go home on the weekends to help take care of his daughter.
"Mummy, Daddy, let's go!" Eileen was pulling her father's hand, making him smile down at her. He pulled Hermione into a kiss and they helped Eileen load her suitcase on the train. After helping her find a place to sit together with Harry and Ginny's children. The two made their way to the teacher's compartment.
"Nervous?" Severus asked.
"Yes, probably more than all the first year's combined." Hermione answered.
"Don't worry about anything, you're Hermione, you faced down Bellatrix and The Dark Lord. A few school children are nothing you can't handle."
"Thanks," Hermione smiled, pulling Severus into a kiss. The two just held each other for the rest of the train ride. Severus never once believed his life would turn out like this, he was ever so grateful for this everyday and wouldn't change anything for the world.
