Remus chuckled, knowing exactly what the man meant. He cleared his throat and
gestured over his shoulder before looking back to see Mia and Sirius step off the train. Mia
laughed brightly as Sirius danced her down the platform, spinning the little witch in his
arms and dipping her low to place a kiss on her mouth. Charlus frowned at the sight, which
caused Remus, Peter, and James to laugh.
"Less happy about this," Charlus said as Sirius lifted Mia back to her feet, taking her
hand in his own and leading her toward her family, both smiling joyfully. "When did this
happen?"
James patted his father consolingly on the back. "Last month."
Charlus turned his eyes toward Remus. "Do I get to blame you for this?"
"Would it help?" Remus offered with a smile, snorting in amusement when Mia
rushed into her father's arms, but Sirius stayed behind a bit, suddenly looking out of place.
After hugging his daughter, Charlus looked at Sirius and raised a brow. "Son."
"Sir."
"Sir?" Charlus laughed loudly. "I haven't been 'sir' to you since you were twelve.
When did I become 'sir' instead of 'Dad'?"
Mia smirked, taking Lily's hand in her own and walking toward the public Floo. She
looked back, likely to see if the others would follow, but Remus shook his head. He spent
hours on the train watching Sirius work himself into a fit as he practised what to say to
Mia's father. They all predicted that the best case scenario was that Charlus would be
thrilled to see his daughter dating his semi-adopted son. Worst case scenario involved a
wizard's duel, and, for twenty minutes, James, Remus, and Peter jokingly made bets on
how quickly Charlus could disarm Sirius.
Having witnessed the rehearsals, Remus was not about to miss the big show.
"When I started dating your daughter, sir," Sirius said.
"Has this been properly dealt with?" Charlus asked, looking at James.
James looked pleased with the awkward way Sirius was standing, his posture
straight. "It's been taken care of. Although, I haven't received any Letters of Intent," he
pointed out with a daring smirk. "Have you, Dad?"
"Not a one." Charlus shook his head, feigning disappointment.
