"It's okay. I'm not mad at you, Pads." Remus thought he understood, a bit, the vested interest Sirius had in seeing his friends' children settled and happy with their parents. He'd seen how his friend had been with baby Harry and wasn't surprised Sirius had taken to Remus' own son with such enthusiasm.
Patting the arm twined with his he sighed softly. "It's just...a lot to take in," he admitted. "I didn't even know he existed until a couple weeks ago. I was wrapping my head around it in theory. But, now he's a flesh and blood human being, calling me 'Dad', and looking at me the way Harry looks at James, only more openly. And, I am no kind of father figure. I can tell him about myself, my parents, but I'm not the man I would have been in ten years, fifteen years. I don't know that man or what he would have wanted his son to know about him. I can't tell him about loving his mother or feeling a connection when he was born...And he reminds me of Tad, and Mam. And...wait. What do you mean he thought I wouldn't like him because he wasn't a werewolf? That's..." Remus shook his head. "That's the last thing I would want for him, to be born with this curse? To suffer like I did as a child? Did he really say that?"
