DISCLAIMER: I DON'T OWN HARRY POTTER.
At the same time the lonely boy was locked up in his cupboard at Privet Drive, a tall man with shoulder length silky, black hair, and a hooked nose, roamed Hogwarts, unable to sleep.
It had been nearly a week since the Dark Lord had summoned his followers. A plan was in the making, and it was going to happen soon.
Severus Snape walked quickly towards his dungeons. He had been thinking of catching up on his sleep a bit with a Dreamless Sleep potion, when he felt a familiar burn on his left forearm. The arm where he had the Dark Mark burned into his skin.
Not wanting to be late, he quickly entered his private quarters and threw on his black cloak and white mask. After slamming the door behind him, he ran out Hogwarts' gates, past the apparition border, and apparated.
With a loud 'CRACK' he appeared at Riddle Manor. He quickly entered the room where the Dark Lord was. He immediately occluded his mind, and bowed down to kiss the hem of his robes.
"My Lord." He said, backing away, and taking his place among the other Death Eaters.
Lord Voldemort was sitting on a throne that looked suspiciously as if it was made of human bones. When all the Death Eaters had arrived he questioned each of them, casting Cruciatus' at all who did not please him. Arriving finally at Severus he questioned,
"Severusss. One of my most faithful. How is it that you have sunk so low.
My Lord? I am faithful only to you" He said making sure to let memories of how much he hated Harry Potter slip.
"Do not lie to me Severus! I know you are a double agent. You are a part of Dumbledore's faithful order. A half-blood no less. I will teach you to honor me once and for all! Crucio!"
Severus writhed in pain on the cold stone floor, as the Cruciatus was held. He could think of nothing but the excruciating pain running through him at the moment. He could faintly remember being dragged off to one of the towers where they continued to torture him.
He felt the blood soaking his shirt and cloak, he knew he had to act fast or else he would die at their , there hadn't been any major torture only a few Cruciatus curses and a few blows to his torso. When he heard them leave he got up immediately, pain shooting through his limbs, and he numbly made his way towards the opening of the tower. There was a huge hole which had been blasted away a long time ago, and under that hole there was a small lake, which ran around the manor.
Severus made his way towards the opening and looked down. It was late at night so the water was jet-black as was the ground below. He could faintly see the outline of the lake and he had a pretty good chance of not hitting the ground.
Severus could hear the footsteps climbing up the tower, so he gathered up his courage and jumped. The water was icy cold, despite it being August. He surfaced immediately thanking God, Merlin, and whoever else was listening that he had learned how to swim at an early age.
He swam agilely towards the shore, as he could hear the others' shouts. As soon as he climbed up onto the ground he started running as fast as humanly possible towards the apparition borders. Severus quickly though of the first place that he would be safe.
If he went to Hogwarts he would collapse once within the gates, his home was uninhabited and he wouldn't be able to stay there because his fellow 'comrades' knew where it was. It only left one alternative, Harry Potter's residence.
He was gone with a loud 'CRACK' and on the doorstep of Number 4 Privet Drive. Exhausted and nearly frozen, he let the sweet darkness engulf him.
A/N: I was debating adding a new character or a surprise visit by Tobias Snape. (Severus' father).
