Luna sat quietly as Dumbledore spoke, holding Rolf's hand tightly in her own, almost afraid to let go. She remembered the times she had fought alongside Harry during her school years, including the battle at the Ministry and the final battle at Hogwarts. She had always answered the call for help, and had loved being part of Dumbledore's Army. But becoming part of the Order of the Phoenix sounded dangerous.
She looked at Rolf, meeting his eyes. He seemed to have similar mixed feelings, before he turned back to Dumbledore and said yes. Luna bit her lip in thought. With the new attacks, she'd been afraid that the world was returning to the way it had once been when Voldemort had been alive. She would do anything and everything in her power to prevent others from experiencing the same grief that she and her family had.
Turning to Dumbledore, she nodded, echoing her husband. "Yes." she said simply, managing a smile at the older man.
