Shamefully it took a week before anyone realized who the second father actually was. Sirius Black. To be fair it's not like they were exactly to blame, Harry very rarely talked about his godfather to anyone, even the two other people in the golden trio nor his wife. In fact the only reason they knew of his existence at all was when James was dared to read one of the books that someone had written about Harry, the chosen one. Sirius Black was briefly mentioned and as such the young potter had asked Hermione about him, the charms teacher just told them that sometimes the past was left buried. When he asked why Harry would want to keep this man from his kids Hermione had sighed.
"James Darling, you probably know that growing up for your father was… difficult. Sirius was a man that your father cherished deeply but the things that attached his godfather are… hard for Harry to revisit."
James didn't leave it at that and had badgered his father, Harry had looked at Ginny for some help but she could provide none. Harry had excused himself from the table and Ginny had grounded James for a week for being nosey. When his father returned he told the children of the man wrongly accused of killing grandma and grandad and whom Harry had eventually led to his death. Harry had the proceeded to take them all on a fieldtrip to Grimuald Place and had handed Teddy a key, making him promise to use it only if he was on the run or needed a place to crash and couldn't get to his apartment.
Standing outside the old Black home they wondered if they were losing their minds. Harry had attempted to clean the place up a bit but hadn't gotten very far. A few of the room that were cleaned out by the order and with Harry's input at least half of the house was habitable. When Teddy entered the house he did the routine spells and found the house uninhabitable. Albus and Lily went to search for clothes and blankets whilst Teddy got to work on making some food, he was just glad that he had brought food with him.
It was an hour later when Teddy went to find James, who was stood in the living room staring a picture of Harry in his Hogwarts robes.
"I hated him you know" James said. Teddy looked at him
"I hated him because he was famous, stupid I know. Rose and Hugo get some of the attention I mean their parents made up part of the golden trio but they weren't drawn to attention as much as us famous potter kids." He placed the picture on the mantelpiece
"We were famous for something we didn't do and I hated him for it. I hated how I'm expected to be just like him, how Albus is penalized for being Slytherin and how Lily… well they say she's going to be married off in some sort of contract. It's horrible but I suppose I get it now." Teddy didn't really know what to say.
"If this is what it felt like for him, running off into the unknown. Yet again he never talks about it so how would we know." Teddy looked down.
"He did… when I was little and he was still grieving over the war he talked about it, people at Hogwarts and work always talked about it but there's a reason he never talked about it to you. I was thirteen, we'd had an argument and I yelled at him that he was not my father and he never would be. I stormed off but later I felt guilty and went to apologise. I found him in his office staring at a picture of my parents and apologising. It may have been twenty years since the war but some wound never heal. Some of his wound never will."
