Both men were pulled out of the memory each in shock of what they just witnessed. Sirius had convinced them to change Secret Keepers. "That was very informative. Thank you Sonny." Dumbledore said as the woman in question changed her godson's nappy. He was trying to absorb what he had just seen. "So you were right Peter was the spy. Why not tell Lily of your suspicions it could have saved their lives?" Remus asked as she used a Scourgify to wash her hands and then Evanesco to vanish the soiled nappy. "If everybody hadn't come back I was planning on it in hopes that she would ask Albus to be Secret Keeper I knew that none of you would be believe that Peter was the spy but Lily would have listened and at least pick somebody we knew we could definitely trust like Albus." She said gesturing towards their former Headmaster. "Judging by the fact that you were certain that Sirius betrayed us Lily never even asked you about James or her becoming the Secret Keeper and they just went with Peter. Those gits most likely strong armed her into using Peter after she told them that I couldn't." This comment was directed at Albus.

"Lily never came to me about becoming the Secret Keeper herself. I would have told her that it was possible and offered again to be the Secret Keeper for them." Dumbledore shook his head at the idea that he had ever doubted Sirius Black's devotion to the Potters, his friends or the Order. "You suspected that it was Peter may I ask why?" Albus queried of his former student. "I have never been very fond of Peter. He didn't fit with the other Marauders. While all the boys were different they made each other better. Peter catered to Jamie's ego and often encouraged Sirius' crueler inclinations. Hell Jamie had to have a talk with him when they figured out where Remus went every month and why." She explained. "That explains why you would think it was him but what other proof did you have? You never would have considered telling Lily based on your own dislike of the man." Dumbledore pushed for an answer. "Among other things Peter has a set pattern of behavior: find the most powerful person he can and cater to their whims in return for the protection. Here at Hogwarts that was the Marauders but out there when things were looking bleak it was…" "Voldemort" Remus stated completed the sentence for Sonny. She simply nodded and both looked to the Headmaster. Sonny's family connections were strong and could help Sirius. Yet if they were combined with a word from Dumbledore it would almost ensure his freedom.

The old wizard cleared his throat, "This proves that Sirius wasn't their Secret Keeper but there is still the matter of Peter and the 12 muggles." "What about Peter and muggles?" Sonny asked confused. "We believed that Peter had gone after Sirius and tried to confront him about James and Lily. The street where Sirius and Peter dueled had been blown up with a blasting curse killing Peter and 12 muggles. Now we know that it was Sirius confronting Peter and the confession at the scene was guilt for making them pick Peter." Albus answered. Sonny thought back to that deep rage she had felt from Sirius he certainly intended to kill Peter but Sirius was a Black if he wanted to make someone suffer it wouldn't have been a blasting curse he would have used the Unforgivables or some obscure curse only to be found in the Black family Grimoire. "Are you sure it was Sirius who cast the spell and not Peter because if Sirius wanted Peter dead he would have used the killing curse it is more precise and wouldn't caused so much damage." Sonny posed to the group Remus automatically seeing where her train of thought had taken her. "But Peter would have needed to cause a scene a blasting curse and a street full of dead muggles would certainly achieve that" said Remus. Albus' interest was piqued as he watched the two worked together to piece together what happened earlier in the night. "We need to set up a trial a simple Priori Incantato would prove if Sirius cast the blasting curse. My memory can prove that he wasn't the Secret Keeper." Sonny said appraising the older wizard's thoughts and feelings. If he helped Sirius then both his godparents would be around to take care of Harry, negating his plan to send Harry to Lily's sister for his own safety of course.

"Albus, I don't need your help to get a trial for Sirius but would you really let an innocent man go to prison because he and I could change your careful plans for Harry. You remember Harry. Small, scared child in my arms he is not a weapon Albus. HE WILL NEVER BE YOUR WEAPON!" Sonny shouted shaking with anger. She truly thought that he wouldn't even have to think twice about helping Sirius. Remus put his arms around her and Harry, not knowing what Sonny had seen in Albus' mind to make her react in such as way. Albus was distressed as she shouted out his thoughts and assuming the worst of not only them but of him. Before he could speak in his own defense she continued on her rant, "We are not chess pieces on a board for you to manipulate and play we are people who foolishly trusted you to do the right thing by us because we stood by you. James and Lily will be the last people to fall victim to your plots no more innocents will be sacrificed for your greater good." Albus properly looked at the young girl for the first time then and saw how much older she looked. Yes, they had been children ignorant of the realities of war when this had started but before him he saw two battle weary adults who no longer believed every word that came out of his mouth though he doubted Sonny ever did. Finally being able to get a word in edgewise he stated, "Lily died to protect Harry. This placed a special protection in Harry's blood through Lily. Wherever Lily's blood flows Harry will be safe. This isn't about keeping him squirreled away from you or making him my weapon. He needs to be with Lily's sister." Shifting Harry to her hip, Sonny showed her right palm to Albus revealing a long thin scar down it. "After Regan died all I wanted was a sister and around that same time Lily was really going through a challenging period with Petunia, she had snapped Lily's wand during the summer holidays. Over the break, we decided to become blood sisters a quick cut with a pocket knife we smashed our hands together and then said a few words. Lily has the matching scar on her left hand." Remus never knew what the matching scars meant but he remembered the bandages that both girls had sported that Christmas when they all stayed in the castle and the various times that Lily or Sonny would call the other "sis" now seemed to make sense.

It would only take a few drops of blood to blood adopt a witch or wizard. Knowing that Lily may no longer be considered related to Petunia changed his game plan he needed to know the words the girls had used and if Sonny had unintentionally blood adopted her best friend. "Sonny what words did you and Lily say, the exact words?" Albus implored the young witch to remember the ritual. "Sisters we were never, now sisters we are forever." She said after a moment to recall the exact wording. Albus eyebrows were to his hairline, "You blood adopted her." "I didn't know it at the time we were 16 and all the kids at the muggle summer camp Regan and I went to would do something like that. We didn't find out what we had done until she went to take her inheritance test before her and Jamie got married." Sonny defended accidentally adopting her best friend but for the first time all night her tone was light and she sounded less like a damaged war veteran and more like a 21 year old girl.

Sighing Albus said, "Well now that it appears that the matter of Harry's blood protection is settled we should get him looked over that looks like a pretty nasty cut. We can eat while Poppy checks him over and then we can figure out how get Sirius cleared and who best to approach with the issue. I can tell you now Crouch will be of no help he plans to make Sirius the face of the Deatheaters." He started to usher the couple towards the door so they could head to the Hospital wing before students started to roam the halls.

AN: Regan is Sonny's half sister she is 2 years younger then Sonny. If you wanna know what happened to Regan well I plan on writing that story too as it shows how Sonny became the person she is. If Sonny seems a little emotionally unbalanced remember she just lost the man she though of as her brother and her sort of sister as well as still being traumatized by what happened to her.
