Six year old Albus Severus stood before his father with a very solemn look on his face.
"Dad," he began. "I told Rose she could marry James, and live with us all the time. She said she can't marry him, because his parents are her aunt and uncle. Does that mean I can't marry Cassie?"
Harry smiled. "No son. You can marry Cassie."
"What about her father is my godfather?" he asked, biting his lip.
"No, that's okay too. You can marry Cassie."
The child broke into a brilliant smile. "Thanks Dad, I just had to make sure."
