Ernie, Audrey, and Hufflepuffs
Standing in the mouth of the tunnel, Audrey watched the students filing away, a part of her desperately wanting to be going with them. But Fiona was still somewhere in the castle, and Sam, and she couldn't leave them to fight alone. Ernie's question struck her and she turned to face him, giving him a wavery smile.
"As I'll ever be," she answered, taking a deep breath and heading back into the castle. Her wand at the ready, Aud glanced back at Ernie before slipping out of the Room of Requirement and striking out towards the Great Hall, from where the sounds of battle were already reaching their ears.
