Written for Whumptober 2020 No. 1: Let's Hang Out Sometime, "Waking Up Restrained."
Ginny wasn't asleep. She wasn't really awake either. Her eyes were still closed, and her mind was half-aware of her surroundings, half-dreaming. She could hear a clinking noise—pots and pans, maybe? She'd thought she was at Hogwarts, but maybe she was home and her mother was cooking breakfast. She didn't want to open her eyes yet, so she felt around with her hand.
Ginny opened her eyes with a gasp. Even though she'd only been able to move her hand a few inches, that had been enough to wake up sores and bruises all along her arm and side. A chain shackled her wrist to the wall.
Now she remembered. She was at Hogwarts. The Carrows had pulled her out of class that afternoon because they suspected she had been involved in the graffiti the D.A. had created the night before. (Ginny had, in fact, been involved in that, but she didn't admit it to the Carrows.) While the spells they'd used on her had been mild for them, she still had many bruises, a cut on her face, and a shoulder that throbbed at the slightest movement.
As far as Ginny could tell, it was late at night now. She'd had no food since lunch, and her mouth was dry and thick. She knew that without water she would have a pounding headache by morning. Ginny leaned her head against the wall, trying unsuccessfully to go back to sleep.
The door creaked. Ginny opened her eyes and squinted into the darkness. A figure was slipping into the room, a figure too small and graceful to be one of the Carrows.
The figure did something with their wand. A dim light glowed on a band in the figure's hair. Ginny could now certainly say that the figure was a girl, but it was too dark for her to see who it was.
The girl knelt in front of her and pointed her wand at Ginny's shoulder. Ginny tensed, but as the soft white light of the spell was absorbed into her shoulder, the pain receded. Ginny could tell it wasn't healed, but it didn't hurt.
Ginny knew now who the girl was: the Dungeon Angel. Two weeks ago, Hannah Abbott had spent a night in the dungeons. Afterward, she told the D.A. that a girl had come and taken care of her, given her water, and numbed her injuries. Seamus had been fed and tended by the same girl when the Carrows had kept him locked up all weekend. None of the D.A. knew the girl's real identity, but Luna had called her the Dungeon Angel, and the name had stuck.
The Dungeon Angel pulled a bottle out of her robes and held it to Ginny's lips. Her hands guided the bottle as Ginny gulped the cool, refreshing water. Ginny let out a sigh of relief when she had finished drinking. Now she felt much better.
Ginny realized that the Dungeon Angel had taken something else out of her pocket, a small reddish-brown pill Ginny recognized from her Muggle Studies book. It was supposed to reduce fever and pains—including headaches. Ginny opened her mouth, and the girl helped her swallow the pill with the last of the water.
Then the Dungeon Angel rose, nodded her head to Ginny, and was gone.
Her pain lessened, Ginny was able to shift to a more comfortable position, though the clinking chains still restrained her. The rest of the night would be much better, yet the Carrows wouldn't be able to detect anything when they came in the morning.
As she fell asleep, Ginny blessed the Dungeon Angel, whoever she was.
Back in the Slytherin dormitory, Astoria Greengrass quietly slipped into bed. She wasn't brave enough to join the D.A. and openly defy the Death Eaters, but she was glad to help those kind, courageous people who stood up for the students of Hogwarts. The Dungeon Angel turned off her light and went to sleep.
