As Severus Snape patrolled the halls of Hogwarts, tired after his meeting with Lucius, he saw the most peculiar thing, there were three pairs of shoes walking towards the stairs to the third floor. At first, he thought some students were playing a prank on him. But he quickly dismissed the idea when he heard a loud sneeze.

'Your hair is so unruly, Granger.' said a voice that seemed to belong to a certain red-haired fist year Gryffindor.

'Seems like Potter and his little friends are out on another adventure.' Severus thought.

He was thinking of bursting the children's ideas of whatever they were going to do but then he knew that he could deduct tons of marks from Gryffindor if he continued to follow them and see what shenanigans they were going to play. Even though he was mentally drained after talking with Lucius, he found himself charming himself to be invisible and walking over to the trio.

As they reached the third floor, Ron said,

'Are you sure you want to do this, Harry? Don't you remember how big that bloody dog was?'

'Yes, I need to do it, we can't just let Voldemort get the Stone, do you know how disastrous that would be?'

'I don't even know why I agreed to come with you two,' Hermione remarked, 'We could get expelled if we're caught.'

As they reached a door at the end of the corridor, Harry slowly opened the door, and they were met with the sight of a gigantic Cerberus staring down at them.

Then, Harry did something Snape would never have expected him to do. He pulled out a flute and started playing the most ear screeching tune Severus had ever heard. Somehow, Cerberus laid down and fell asleep.

'Come on, we need to reach the trapdoor but remember, be quiet.' cautioned Hermione.

When they all jumped down the trapdoor, into pitch-black, they felt something was twisting itself onto their bodies, slowly being tighter and tighter.

Harry and Ron screamed bloody murder and Hermione said in a shaky voice,

'It is the Devil's Snare, it's sensitive to light, do you guys have any wood to light a fire with?'

'Have you gone mad? Are you a witch or not?' Ron yelled.

Hermione immediately casted Lumos Maxima and the Snare backed off and dropped them onto the floor with a cold hard thud.

They walked through a door and found many little objects flying in the air. They found out they needed to use a broom to fly and catch one of the objects which was a key to the next room. Severus for once was pleased that Harry has amazing Quidditch skills.

Then, they needed to play a game of 'Human Chess', Ron needed to sacrifice himself to help Harry pass the obstacle, he collapsed onto the floor and told Harry and Hermione to go on without him and they promised him that they will come back for him.

The next obstacle was a potions one and a tricky one. Harry knew that if he didn't have Hermione, he would be dead. They passed that obstacle and Hermione wanted to stay back and take care of Ron. So Harry ventured on his own.

When he entered the room, he did not anticipate to see his DADA teacher standing in front of the Mirror of Erised.

At that moment, he heard an inhumane voice come out of nowhere,

'Let me see the boy.'

'Yes, my master.' said Quirrell as he unraveled his turban that showed a horrifying face on the back of his head.

'Hand me the Sorcerer's Stone, boy.' the face said.

Harry realized that it was actually Voldemort talking to him.

'I don't have it.'

'Do not lie to me, you foolish child, I know you have the stone.'

Then, Harry saw that he had the Stone in his hand in his reflection on the mirror.

Suddenly, Quirrell was charging towards him so he put his hands out and a scream was let out by Quirrell. Harry saw he was melting the skin off Quirrell until he passed out.

Harry was very tired after the entire situation, and he got up to go back to Ron and Hermione, but he collapsed in a heap. Severus, who had been following him through the entire incident, felt like he should be doing something and so he dropped the charm and rushed over to Harry. He saw that he drained all of his magic energy and if he didn't heal him in time, Harry was going to fall into a deep coma. Therefore, Severus used his magical energy to help Harry recover, he saw that his face was slowly regaining some color. He transferred his energy to him until he was fully conscious.

'Professor?' said Harry as he blinked groggily at his potion's professor.

'You alright Potter?' asked Severus tiredly.

'M'fine. What happened?'

'You used all of your magical energy up, and I transferred some of mine to you or else you would've gone into a coma. We need to go to the infirmary. You just had a traumatic experience.'

Harry nodded, a bit too stunned to speak.

He started getting up and they were walking towards the door of the room, Harry went back to Ron and Hermione.

'Where did you come from, sir?' asked Hermione.

The children all looked at Severus's paler thank normal face and were a bit worried about him.

They were walking back to the trapdoor. All of a sudden, Severus fainted onto the floor.

'Professor?!' yelled all of them in unison.

Harry checked if he was breathing, and said,

'He is breathing but it's very faint, we need to give him immediate medical attention.'

Just then, the greasy-haired, sallow-skinned, skinny man's face morphed into a handsome, young-looking face.

'What the bloody hell is happening?' asked Ron.
