The next morning; the Tonks-Black-Potter household was full of life as the five people within got ready for the day. Andromeda had stumbled back in shock when she'd gone to the kitchen to find Harry trying to cook breakfast for everyone.
She had to restrain herself from going to the Dursleys to hex them when she'd questioned Harry to learn he'd always made all the meals at the Dursleys since he was three. Instead, she slowly calmed herself and explained to Harry he didn't need to worry about cooking for everyone as that was for the adults to do.
When he started to protest, she did leave it open to him to help her since he was already up. That had cheered Harry up and together, they'd prepared breakfast. Sirius was the first to come downstairs when the food was ready.
"Morning Andy. Morning Prongslet." Sirius greeted. "It smells good in here."
"Morning Siri." Andromeda smiled at her cousin.
"Morning." Harry replied with a smile. "Um, Sirius, why do you keep calling me Prongslet?"
Sirius sighed and ran his hand through his hair. "Well, Harry. I know you heard Minerva call me your godfather yesterday, right?" He waited for the boy to nod. "Well, it means your parents chose me to look after you should something happen to them. A misunderstanding kept me from getting you sooner. But I've been calling you that since I first got to hold you after you were born. A reference because I used to call your father Prongs."
"Oh. Andromeda told me yesterday that we can all do magic. Was magic involved as to why you called Dad that?" Harry questioned.
"A very special type of magic. It's one I can do as well. And when you're older, if you want, I could teach you too." Sirius smiled. "Wanna see?"
Harry's face brightened at that. "Can I see?"
Sirius gave one of his infamous barking laughs before shifting to his Animagus form, a large black dog. Playfully, he pounced on Harry, knocking them over to the floor and licking Harry's cheek enthusiastically.
"Ah! Okay, okay! Stop it Pa'foot!" Harry squirmed under the energetic dog.
Sirius, or Padfoot as he was called in Animagus form, stopped licking at hearing Harry say a version of his nickname. He shifted back and stood up before helping Harry up. "You...remember?"
"Remember what?" Harry looked in confusion. "Oh...Was that something I called you?"
Sirius nodded in bewilderment. "That was a nickname for me amongst the group of friends your father and I were in...the Marauders, we called ourselves. You couldn't fully say 'Padfoot' so you just said 'Pa'foot' instead. I didn't think you even remembered me that little bit." He started to stumble back.
Andromeda quickly moved a chair under Sirius and watched as he dropped into it. "Careful now Siri. There's still things to do like taking Harry to get some new clothes and all."
"Right. You're right. Anyway, pup, feel free to ask me anything about your parents." Sirius smiled again.
About that moment, Ted and Celeste came down. While Celeste was a little apprehensive about the new kid in her home, she soon took to Harry while they all ate breakfast. Even showing off her metamorphagus abilities to help him feel more at ease.
After breakfast, the five went to Muggle London; first to get Harry necessities such as clothes that fit along with toys of his own and books to read. From there, it was on to Diagon alley to get things for the house as well as some cloaks and other things for Harry to help him stay warmer. And of course, to Gringotts to get Harry some funds from his vault and to set up for the reading of the Potters' will.
Days later, the Potters' will was read at Gringotts with the Tonks, Sirius, Harry, Augusta and Neville Longbottom, Minerva, Severus Snape and Remus Lupin all in attendance. It was revealed that after Sirius and Alice Longbottom, that the other people listed to take in Harry were Severus and Minerva.
Also revealed at the beginning of the will was the mention that if they were dead then it was because Peter had betrayed them.
Minerva was touched at having been included as someone who could've looked after Harry in James' and Lily's places. She did think of her Gryffindors as her children, which made sense considering how much time in their lives she spent with them at Hogwarts.
So to hear that two of them had thought enough of her as a second mother to list her to take care of their son warmed her heart. She knew right then, she would continue to do whatever she had to to protect Harry, whether it was from Voldemort or from Albus' manipulations.
Severus had been only partly shocked to hear his name on the list of people to take in Harry. Upon seeing the shock on the faces of the other adults in the room, he admitted that he had made up with Lilly and had even made a truce with James with eventual plans to make truces with Sirius and Remus.
That it was because of him that the Potters were able to go into hiding and that he'd had no knowledge of Peter being a Death Eater or he would've warned them. In honor of his fallen friend, he'd made a vow to protect Harry, part of which involved being a spy amongst the Death Eaters.
By the end of the day, Severus had made peace with Sirius and Remus and it had been agreed for Celeste, Harry and Neville to regularly be brought together to play and learn even if Celeste was a year older than the two boys.
