Severus Snape looked down at the crying child of his most hated rival not knowing what to do with him. James and Lilly Potter were dead killed by the Dark Lord and yet the boy lived banishing the Dark Lord. Severus wasn't a fool he knew Voldemort would find away to return to the living. He found out too late about Pettigrew turning against his friends and came to warn the Potters. It was true that Severus hated James Potter however Lilly was his best friend who stood at his side when his father forced him to join the Dark Lord. It was her idea to become a spy for Dumbledore.
"What am I to do with you?" Severus asked the baby picking him up causing him to quiet down. "If I leave you here Dumbledore would find you and use you as a tool to fight the Dark Lord." Maybe there was a way, but it was dangerous. Severus didn't see any other way. "It's the only way I'll know you'll be safe." He gave the young Potter a small smile.
"What in bloody hell is going on here?" Severus jumped when he saw Sirius Black appear. "What are you doing here Snape and where is Lilly and James." Sirius narrowed his eyes in rage when he saw whom Snape was holding. "What the hell are you doing to Harry?"
"Nothing Black, I came to warn the Potters." Severus placed Harry on the ground. "I was too late they're dead killed by the Dark Lord."
It was then that Sirius noticed James's body on the ground. "No!" He kneeled beside the body of his best friend taking him into his arms rocking back and forth. "This is your fault, Snape and I'll make sure you'll pay." There was pain in his voice and the promise of death.
Severus snarled, "I came to save them Black it was Pettigrew that turned on his friends."
"Peter wouldn't do that to James." It couldn't be Peter is their friend. He wouldn't do that to them not to Lilly and James.
"Then tell me Black how the Potters were found." Severus over heard Lucius and Pettigrew talking, he knew their plan. Sirius was going to take the blame for everything once Pettigrew faked his death. "I overheard him speaking with Lucius that's why I came to warn Potter."
Sirius didn't know if he believed Snape he was a Death Eater and a Slytherin. "How do I know if you're telling the truth?"
"You don't." Severus watched Black place James back on the floor as he got up taking Harry with him. Black had no idea that he was spy for Dumbledore or that he was Lilly's friend. They knew he wouldn't have taken the news well. "You have to take my word for it."
Sirius would never trust Snape. They have been enemies for too long. "We'll need to contact Dumbledore he'll know what to do."
"Dumbledore won't solve a thing." Severus knew that for a fact he only saw Black, the Potters, and himself as pawns in a game of Wizard's Chess. "He'll use young Harry as a tool against Voldemort once he returns. Is that what you want."
"What do you mean return, Snape." Something happened here before Snape arrived. Harry was alive the only injury was scar on his forehead. It didn't take long for Sirius to figure out what happen.
"The Dark Lord is gone thanks to Potter's child." Gone for now, but he would return and Merlin helped them when he does. "It's only a matter of time before he finds a way to return to the living."
Sirius rubbed the scar on his godson's forehead. "Then what are we suppose to do, Snape?"
"We have to send Harry away." Severus saw the raw pain enter Black's eyes. "There is no other way."
"There has to be I'm not losing my godson he's all I have left." Sirius tightens his hold on Harry afraid that Snape would try to take him from his arms. "I'm not letting him go."
Severus knew this wasn't going to be easy, but time was running out he had to make Black understand or just take the child. "Black everything has changed. Pettigrew has faked his death and blamed you for it, that and the Order thinks you are the Secret Keeper."
Sirius was starting to understand. "They will think it was me that turned on James and Lilly not Peter."
"Dumbledore will use Harry as a tool like he does to us." Severus knew Dumbledore didn't care what happens to his soldiers as long as Voldemort is destroyed for good. "Do you want that to happen?"
No, he didn't and he didn't want to lose Harry either. "What do you have planned, Snape?"
"There is an old time traveling spell we can use and a potion that will protect Harry until he's found by a decent protector." Severus held up his hand when Black was going to speak. "Dumbledore wouldn't be able to touch him and he'll be safe."
"Time traveling?" Sirius would never see his godson again.
"It's the only way Black." Severus didn't see what else could be done.
"Alright." Sirius could feel his heart break in half. "Let's do this."
The potion only took three hours to complete since Severus already had most of the ingredients on hand. Sirius watched Snape make the potion while Harry slept in his arms.
"It's ready." Severus poured some of the potion into a small silver cup. "The brat will have to drink the potion."
Sirius nodded waking Harry up. "It won't hurt him?"
"No, he won't feel anything." Severus wasn't such a bastard that he would cause a young child pain. He handed Sirius the cup. "He has to drink it all."
Sirius used a spell to make Harry think the potion was a sugary drink getting the boy to drink every drop. "It's done now what?"
"You have to help me open the portal it takes a lot of magic." Severus handed Black a old scroll dated back to the time of Merlin. "We have to hurry."
Sirius sat Harry down on the floor and stood next to Snape with his wand out. As one both Sirius and Severus said the spell and a large portal appeared in front of time glowing a deep blue. Severus picked up Harry. "You'll see him again Black."
Sirius bent down kissing Harry's forehead where the scar was holding back his tears. "Just send him though we have to leave."
Severus nodded placing Harry on the ground letting the child crawl into the portal once he was in it closed behind him. Severus turned to face Sirius seeing tears going down his face. "We have to go now, Black." He could feel the wards around his home falling.
Sirius nodded as he followed Snape out of the room. They were going to have to run and hide now from both sides. Sirius could only hope he would see Harry again.
