Andromeda didn't quite realize that she still hoped for a reconciliation between her new and old families until the chance snaps out of reach. Ted gets the owl post before she does, and it's from Nymphadora, and he shouts "Hufflepuff, Andromeda!" with such unbridled excitement that she pulls a smile across her lips.
For Ted, Andromeda puts on a brave face. For her daughter too, because if someone as strong and good as Ted can come out of Hufflepuff, surely her daughter shall become just as strong and good. But inside, the little bit that remains Black despite everything withers to dust.
She can imagine what she'd secretly wished for her family to be able to say to her, these past eleven years waiting for Nymphadora to grow up. "You made a poor match," her mother might say, and Andromeda would set her chin and stare defiantly at the ground. "But your Nymphadora in Slytherin; she is a true Black. Perhaps she can be forgiven for the bad blood on her father's side as she inherits only the purest from her mother."
And maybe forgiveness would be bitter, maybe some lines could never be crossed, but Andromeda remembers the way she and Bella said always: She never imagined that always was as mortal as the society she fell from. It's been thirteen years since Andromeda has been a Black, and she's ready to be one again.
But Nymphadora goes into Hufflepuff, Ted can barely speak from smiling, and Andromeda has to accept that this is her only family now.
Probably not as good as it could have been, but alas, such is life. I'd love to hear any thoughts.
