This IS working
There was shouting, and there were wands, and the blond boy - she'd never liked him much - was laughing and she wanted to stop it, stop them, because they were going to hurt Abe.
But the flashes of light were everywhere. Reds and greens and golds and purple, and she flinched and cringed even as she felt her own magic swelling. She fought it back, fought it down, but it escaped anyway. It always did. "Stop it, stop it!" she called out, closing her eyes and clamping her hands over her ears as if she could somehow drown out the sound of it, the sight of it, as if by not seeing it she could make it not happen.
Ariana screamed once, high and shrill and for a moment she felt a pause in the flashing magic before another jet of light flashed; she saw even with her eyes closed the brilliance of it, and then ...
She snapped her eyes open with a gasp, her body twitching and jerking. The magic was long faded, even she could feel that, it wasn't fresh, it wasn't there, the room didn't reek of it, but then where ... where was she?
"Abey?" her voice was a weak croak to her ears, and she thought her eyes must still be closed because her world was dark and kind of foggy. She cleared her throat and tried again. "Abe?"
Her voice was stronger that time, though still not as strong as it could be. Sniffling a little, Ariana felt her way along the floor. Small pale hands found what felt like legs of a wardrobe, and she patted her way up it, using it to help her stand. Where were her brothers? Where was Albus' friend? She blinked rapidly, but it did nothing against the grey fog obscuring her vision. Leaning her head against the cabinet, she sniffled and tried not to cry ... but they didn't have a wardrobe like this. Not downstairs and not anywhere else in the house.
And she would know.
Turning slowly, she pressed her back to the closed doors of the cabinet and listened. Soon she heard footsteps, voices, and her head cocked curiously to one side. She had to hide, but where could she when she couldn't even see where she was?
"Oh, Merlin..." The voice was deep and rumbling, male and unfamiliar.
"Do you know her?"
"No. But I know who she is."
Ariana whimpered quietly, clinging to the cabinet. "Please," she whispered. "I have to find my brother. I have to be sure he's okay."
Gentle voices and gentle hands pried her away from the cabinet, lifting her up, carrying her away. She couldn't see still, but she clung to the warm cloak of the wizard carrying her. She could walk just fine, she supposed, but it just seemed easier to let him take care of her.
She asked questions and received unsatisfactory answers, so after a while, she simply fell silent. Eventually ... she fell asleep.
When she woke up, sometime later, the room was dark and she was in a bed. She gave some thought to getting out of bed, going to the door, finding someone who knew where her brother was ... but before the thought was even completed, her eyes fluttered closed and she was sound asleep again.
