Hermione woke up that morning with the sun bathing on her face. Her eyes were half-close, being not used to see that much light after a night of sleep, though se thought the warmth was really nice on her skin. The birds were chirping happily outside. She stiffed a yawned and turned to see she was not alone in her bed. At first she was surprised and almost fell on the floor as she tried to move back but realisations of the last night flood back quite quickly. She smiled. Severus was cute sleeping like this. He seemed harmless. She began to stroke his hair tenderly, dreamingly too. 'His hair are so silky… Who would have thought!' She continued to play in his hair dreamingly for some minutes, hoping she would not wake him up. 'Such a nice Friday morning…Wait! Friday! Which hour is it?' she stopped abruptly stroking his hair, the hard move waking him up.
"Ow! You could watch yourself a little!" he frowned.
"Severus we're in deep shit! We are late for potion class!" she said with a panicked voice now that she saw that it was nine in the morning.
Severus jolted from the bed, muttered a charm to replace all the covers, rushed to his room and dressed as quickly as he could. Hermione did the same on her side. Less than five minutes after they were ready to leave her prefect personal room and began to run to the dungeons. Naturally, their behaviour did not remain unnoticed.

As they were approaching the stair that leaded to the dungeons, Hermione bumped into professor McGonagall. Her eyes widened in fear.'We really needed that, on top of all!' Severus stopped on his way and joined back Hermione.
"Hermione, William… Why this hurry?" she raised an eyebrow.
"Professor, we're late… We overslept!" Hermione said desperately, hoping she would let go of them quickly.
"Late for which class?" she inquired.
"…Potions." William said lamely.
"Oh. This is no good. No good at all. Severus will jump on this opportunity to take many points from our house. Even more because you are a prefect Hermione."
"Do you think that he will really take points away from me…?" said William bewildered.
"You are now in Gryffindor my boy and he will certainly take a deep pleasure in taking points off of his rival house. Even if he must take points away from you."
He stood there surprised of what he had become.
"I shall go with you at your class. Telling him a good reason not too takes points away from you." she nodded approving herself of her own plan.
Hermione and William couldn't believe their luck. A teacher helping them to not lose points! Even if what they did really deserved a loss of points! They followed professor McGonagall to the potion class and just before they entered Hermione remembered of something important.
"Professor! Could you just please wait a second before opening the door, there is something important I must do."
Minerva raised an eyebrow. "Proceed." she only said.
Hermione turned to look at William who gave her back a puzzled look. She took out of her bag one pen and transformed it into a little elastic.
"Attach your hair." she said pointing the little transfigured object.
He mumbled but did as she said. Hermione told him before they were with Slytherin in this class, so Malfoy would be with them. He knew he couldn't let any chance for him to let him recognize him.
"We're ready." said Hermione to her professor when Severus had finished putting on his hair into a small ponytail.

Professor McGonagall opened the door of the classroom with the two worried students walking behind her.
"Professor McGonagall! What a surprise! I could never have guessed you would visit me today…" said mischievously professor Snape.
Minerva frowned. 'Strange…' she thought "I was only here to…"
"…to invent piece by piece the reason for why they are late to my class because you didn't want me to take out points away from your dear prefect and her protégé? Too sad I saw this coming, is it not?" he smirked. "The truth is the two of them overslept this morning."
Professor McGonagall stood there dumbfounded. How could he have used legilimancy on her? She never let her barrier go down.
"...Though I'm impressed, Minerva. You didn't even ask them why neither of them has forgotten to put their magical alarm in their respective room…" he sneered.
Professor McGonagall turned around to look at the two students who were now blushing furiously, looking at the floor, then at professor Snape and once more at the two students. It was then that reality struck her. Her eyes widened. 'Severus knows everything because it is his past!'
Professor McGonagall cleared her throat and turned back to look at professor Snape who was enjoying too much the situation and the advantage that he had in it. 'How can I go out with dignity from this mess…?'
"Severus, it deceives me you give me such bad intention. I was here to inform you that, indeed, our young mates have overslept. I was also here to tell you that I took charged of it and punished them for their lack of punctuality."
"Oh really? So how many points you took away from each of them, Minerva?"
"Fifty points each." she stared at professor Snape in the eyes, not wanting to show him any weaknesses.
"That's harsh don't you think? I would only have take twenty points away from each of them. But well, what is done is done…" he smiled at her in triumph.
Professor McGonagall frowned, knowing he was only playing with her nerves. She turned at the two students, put her hands on their shoulders and muttered. "Sorry…" and she left the classroom.
---
"Well… What are you waiting for? That I take more points away from you? Sit down!" professor Snape spat.
They looked around quickly to some place in the room and the only one left was in the front row of the class. Hermione growled.
Professor Snape continued to where he left the lesson before being disturbed by professor McGonagall and after five minutes of teaching he asked them to do the potions at the page forty-five of their book.
Hermione and the young Severus began to settle their things down and cut the first ingredients to be put in the potion.
Professor Snape looked at his younger self and sighed. 'How can he, I, fall in love with her? I can't believe we slept together! At least, we just…slept! I must stop this stupid affair at this instant, before it becomes out of hand…'
---
"No Sev…William, it's not what the book says. You don't want professor Snape to be angrier at us, do you? We must succeed this potion." She said sternly.
"Believe me! It gives better result, I experienced It before!" he claimed.
"No! Sorry, I can't take the chance!"
He frowned. "Ok then…" The young Severus turned around to be now in front of his desk and began cutting the beetles as he knew it should be cut and put it in the potions, not listening to Hermione.
"What are you doing? You'll mess the entire potion!" she said angrily at him, not talking too loud because she didn't want to be noticed, again, today.
"Look! It works. As I said." He said pointing at the potion.
She stood up to take a better look at the potion and gapped. "Y-You're right… You really are insufferable you know that!" she pointed out smiling a little.
"Impressive Mr. Greenlake. Must be hard on the know-it-all pride to be surpassed." he sneered and turned to look at his younger self. "Mr. Greenlake I need to talk to you after class. Without Miss Granger." he turned and went back to his teacher desk making his cloak billowing behind him.

"Aren't you aware of the consequences?" professor Snape shouted as soon as everyone of the class has left but the young Severus.
The young Severus stayed silent.
"Have you only thought for one second how your caring for the bloody know-it-all is unhealthy?" he growled. "You did not think of it, isn't it? It is not your time! Your world! You must not change a thing here. You must stay the most invisible as you can! Not doing a scene like at the beginning of the class because you slept with her last night!"
Young Severus looked up with a quizzical look of his face.
"Surprise! Yes I know everything. Because, guess what? You. Are. Me." he snarled.
Young Severus frowned. "No." he simply said.
"No what?"
"I'm not you. I will never be you. I will not become the miserable men you are. Pitiful really… living in the shadow of a loved one. Forget her! She's gone! But you are not! It's not because you put a term in your life that I will! I will not make the same mistake as you did." he spat.
Professor Snape was furious. 'How dare he talk to me like this?' He stood up, and grabbed the arm of his younger self, hurting him. "I will not let anyone speak to me like this, have I made myself clear?"
A sob escaped from the younger Snape throat, not able to pronounce a word. He was frightened. When the older self noticed what he had done, he let go of his younger self miserably. "Sorry… I shouldn't."
The pupils of the younger self were trembling. "You know the more I see you… the more you make me think of father…" he merely said out loud.
Professor Snape blinked at that cold remark. Truth hurts.
The younger self put his hand on his swollen arm and looked intensively in the eyes of the one with the dark past. "Look. I will not make myself invisible, I've been invisible for too long. I have friends. You should be happy, no? Don't you remember how you felt when you betrayed your only friend? When she left you for that Potter? I'm tired to be alone… I've now got some people who like me for who I am, like Lily. I will not do the same mistake again."
"You are friend with the son of the one you call 'that Potter'… Isn't this betrayal too? To you?" he said in a rasped tone.
"He's is son. Not him." he simply said. "I know what you hate more about this. It's that you can't help feeling the same feelings that I have. Your feelings for Hermione are the same than mine and you're afraid of them."
"Damn boy! Don't you think it's normal? I'm twenty years her senior! What will happen when you'll left this world and that she'll stay if something happen between you too? Have you only thought about that! One blasted day and you sleep in the same bed than her! Must I be afraid that tonight you'll do more? I'm a teacher; I must have superiority on her. If you have a relationship together, you can forget about to authority I have on her…"
The young Snape sighed. "I won't do anything I'll regret in twenty years… I swear."
"Good… You may go." he pointed the door at him while he stayed leaned on one student desk. When the young Snape left, the older one buried his head in his hand, falling on his knees.
