"Fuck off" Harry spat as he turned on heels to leave.

"No, wait, its true" Severus pleaded, "Harry wait"

Harry stopped dead in his tracks. Not once in the 8 years Harry had known Snape had he ever used his first name and that really hit Harry hard. He turned and looked at his former professor.

"Why would Dumbledore ask you to kill him?" Harry asked. 'That makes no sense"

"I agree" Snape replied, "but I made a promise"

"I don't believe you" Harry barked.

"Then check my pensive" Snape countered.

"Memories can be altered" Harry said, remembering Slughorn and the memory of Tom Riddle

"Yes they can" Snape agreed, "But you can tell when a memory is altered. Take Remus with you and he can verify that the memory is real."

"Why should I help you?" Harry asked. 'For all I know you are distracting me from finding out who my sister is"

"I will make a deal with you Potter" Snape said, "Get me exhanerated and I will tell you who she is"

Harry thought about this for a moment, he didn't believe Snape for a second but what was the harm in it. If he was guilty he would just leave him here to rot and keep searching for his sister. "Fine" Harry replied. He turned and left Snape there in his presumed guilt.

"Harry"Remus said looking relieved as he threw the door open. 'We have been worried sick.'

"I am still really pissed off at you" Harry said walking into the kitchen at Grimmauld place. "You helped them keep my sister from me and it's going to take me a while to get over that"

"Ok" Remus said.

"But I need your help" Harry continued.

"Anything" Remus replied happily.

Harry sat down and explained his journey thus far. Remus listened patiently until the end.

"That bastard wants us to believe he is innocent" Remus exploded. "After everything he has done, he expects to get out."

"What could it hurt to research this Remus?" Harry asked logically.

'I guess it wouldn't hurt" Remus admitted.

'Then how do we find Snape's pensieve?' Harry asked.

"Well only one of three could have happened" Remus explained. "Either the Order took, the death eaters took it or the ministry did"

"Ok" Harry answered. "How do we know which?"

"Well I know for a fact we don't have it" Remus said. "I would have been notified"

"So either the death eaters or the ministry?" Harry asked. "How do we know which?'

"Follow me" Remus said with a wicked smile.

Remus took Harry up to the attic where they were keeping prisoners. Remus led Harry down to the end. Harry saw Lucius Malfoy chained to the wall and laughed.

"When did we get him/' Harry asked

"Last night" Remus replied, "You should have been there it was glorious"

Harry walked over and took the gag odd the elder Malfoy. "I have question, did the death eaters confiscate Snape's pensive

"I have no idea" Malfoy replied, looking bored.

"He's useless:" Harry told Remus. 'Kill him"

AS Harry was walking away Lucius cried out to him, "Ok, I might no something"

Harry turned around, 'I am listening" he said.

"We broke into Snaps home the night Dumbledore died, all the things we found we took to my home. They were stashed in the basement"

"Thank you" Harry replied, he turned to Remus, "Turn him into the ministry, I think that's all he was worth"

Remus nodded and put the gag back over his mouth. The two men made they're way back downstairs and to the fireplace. Remus stepped with a hand full of powder, "Malfoy Manner" he cried and Harry quickly followed suit.

Harry wasn't at all surprised by Malfoy Manor, it was flashy but hollow, kind of like every Malfoy Harry had ever come across. Remus and Harry made their way to the dungeons of the manner and in a very back corner were the belongings of Severus Snape.

The Pensieve was in a box in the back and Harry found it quickly. He took it out, his wand hovering over it." Ready?' he asked Remus. The older man nodded and Harry swished his wand over the surface. Harry had to wade through many a memory until he found what he was wanted.

Harry could tell by the appearances of the men that it wasn't long before Dumbledore's death. Snape was standing in front of Dumbledore's desk.

"Narcissa asked me to make the unbreakable vow" Snape confided, "I didn't want to but I knew my refusal would get back to the Dark Lord. I had to"

"I understand Severus" Dumbledore told him gentle. "Do you know what it is Draco has to do?'

"No, the boy won't tell me" Snape replied.

"I know what it is he has to do" Dumbledore said after a moment of silence. "He has to kill me"

Snape looked shocked and terrified, 'We have to find a way to stop him" Snape said, "he doesn't want to be like Lucius, Draco is good, he feels like has to"

"I know" Dumbledore cut him off, "But it's too late now Severus, I only ask you one thing"

"What?" Snape asked sharply.

"When the time comes, do not allow Draco to kill me" Dumbledore implored, "Do it yourself"

"I couldn't Albus, I wont" Severus insisted.

"You must" Dumbledore advised him, 'It's the only way to save Draco from Lucius and himself"

Snape was quiet for a moment but solely he nodded his head and left the room wordlessly.

"He was telling the truth" Harry mumbled. Remus nodded his head. Both were shocked, it was so easy to believe Snape was the bad guy.

They knew what they had to do and that was go to the ministry. Kingsley was shocked when Harry and Remus presented their evidence but it warranted Snape a new trial.

Harry went to Azkaban to tell him the good news. Harry decided on the way that this changed nothing. Snape may not have been a murderer in the sense that everyone believed but Harry didn't have to like him.

"You are being granted a re trial" Harry told the Snape once he entered the small glass room. Snape didn't say a word, simply nodded. 'I held up my end of the bargain, now you hold to your"

Snape nodded his head and reached into a bag on the bed. He pulled out a piece of parchment and handed it through the small window to Harry. Harry took it and read.
