"That's her call, love," Sirius replied, "She can be fiercely independent, but assuming things about her never goes well. And you've got a lot of catching up to do on getting her easily. Remus, her dad, is one of the best at that. But he's known her since she was born. You'll get back in the game, I promise." He was glad that Remus wanted to know her. He wanted Remus to get to know all of them, all of his family in Sirius's world. That's what they were, one very large very close family.
"Remember, Remus, always, that I am from Baby World," Sirius countered, taking pleasure in Remus's response the same way he had when it shocked someone, "I was married at eighteen and the father of triplets at nineteen. We all get married pretty young in my world, but I do get on that whole family business first. Also became head of my family, helping a grieving mother and Reg, and dealing with dad's death." It was a lot of changes in a very short time. But he'd grown up more as a man than he ever had with growth spurts.
