'Calm down Tonks, let us explain Sirius's presence here.' Remus said with a shushing tone, looking serious this time

'Why should I trust him or you?' I said trying to keep my voice steady.

Another man stood up from his seat: Albus Dumbledore.

'Nymphadora,' he spoke, 'Take a seat and we will explain everything to you.'

'Okay, I will sit down but explain it quickly or I'm going to call the other aurors.' I warned and I took a seat waiting for an explanation that better be very good.

.'I think we should start at the beginning, that would be the night Sirius escaped the first time from Azkaban..' Remus began, 'But I think it's better that he explains it himself, don't you Sirius ?'

Remus glanced at the other man, who sighed and took over.

'Okay, well you know that my escape was followed with all kinds of rumors that I learnt things from Voldemort to escape was one of them.'

'Of course and they were right weren't they ?' I spoke out loud, 'how else could you have escaped that prison!'

'I'm an animagus Tonks, an illegal though.'

I laughed, he really had thought this over and over.

'Hah, an illegal animagus you say and why on earth would you become an animagus unless you had to spy for Voldemort or something?' I asked him.

'Listen, all you need to know is that I became one just to help a friend, I don't think that's so bad is it?'

Sirius answered.

'But what friend could use help from you if you became an animagus, explain that !'

Remus took my arm and stopped me from coming out of my seat.

'Calm down Tonks, ' he said with his calm voice,' I was there and I can assure you that it was really a great help for that particularly friend that he and some other friends became animagi.'

I think it was of the honest look he gave me that I believed Remus, but that didn't meant that I would believe Black!

'Listen to me , I never, EVER, had something to do with Voldemort and all his distasteful practices'

Sirius took a deep breath and continued.

'Many years ago I lost my best friend and his wife, James and Lilly Potter, everyone thought that I betrayed them, because they thought I was there secret keeper, but I was not,…

He sighed.

'The evening before their dead I switched places with Peter Pettigrew, the betrayer, little did we know that he was a traitor among our friends.

'He was a spy for Voldemort and went of course straight to him with the hiding place of James, Lilly and their son Harry, meanwhile I had a bad feeling about it all so I went to Peter's house to find it empty without any fight,…'

Sirius grunted.

'I went straight up to their house but, I was too late,…' Sirius said with a lump in his throat.

'From the house was nothing left, and there body's ,…' Sirius rushed away a tear,' then I saw Hagrid he came walking at me with the little baby harry in his hands.'

'After he refused to give him to me my mind went completely blank, I offered Hagrid my motorbike and went off on a search for that traitor, that rat !' he almost shouted.

'And I found him, oh yes I found him in an alley full with muggles, he said that I had betrayed James and Lilly and then the moment I was going to kill him, he blew up the whole street with the wand he was holding behind his back.'

'After that he quickly changed into his animagus form, a rat, and,…

'Wow wow wow ,I interrupted his story, ' Peter Pettigrew was not an animagus they researched that when they investigated the whole case, they searched through all the registered animagi and,…'

'Ah, ' Sirius said,' but what they didn't know was that he was an unregistered animagus, just like me and James…'

'Oh, so now there were 3 animagi ?'

'Yes but really Tonks you have to believe me, look I would never ever kill my best mate, I would rather die than betray my friends, PLEASE believe me .' he looked at me waiting for my answer.

When I saw how vulnerable he looked I clicked all the bits of the story together and finally I understood it…
