“Windows. Right. Easy.” Marlene sloshed after Mary, water dragging heavy at her boots as it climbed higher. She jabbed her wand at the glass. “Reducto!” The spell cracked against the pane but fizzled away like it had hit solid stone. Another blast did the same, the window gleaming smugly back at her. “Of course. Because why wouldn’t bloody glass be indestructible?” she muttered through clenched teeth, hair dripping into her eyes.
Her gaze snapped to Mary on the desk, and for a heartbeat she let the panic in. “We could try Apparating—” she called out, raising her voice above the rush. But the magic in the air was heavy, suffocating, every spell already sliding off the walls. Even as she said it, she shook her head. “No. Wards are too thick, it’ll splinch us to pieces.”
The water surged, icy now at her thighs. Marlene gave a short, determined laugh, the kind that dared the fear to touch her. “Well, no use waiting for a lifeboat.” She shoved her wand between her teeth, pushed off the desk she’d been clinging to, and dove into the rising water—kicking hard to reach Mary.
There was too much water now. It was building like it was trying to cover every surface with a great venacity. Mary knew a few water spells. In fact, she knew about five at the top of her mind. But she couldn't think of anything to get rid of water and absorb it all away. "Don't-" she said but it was too late. Mary assumed there was a spell on it to double its defense if provoked. Clever, she thought. "It's only to get worse if we keep messing with it," she said then after a moment. "Give it to me, we can bring it with us. Give it to someone else in the Order who knows these kind of spells." It would also borrow them more time to get out of there. To focus on something other than slowing down her breath. Mary made another failed attempt at the window. By now, she was wading her way through the water that was at her hip. She stood on the desk and watched it collect around them. "There has to be a trick door-don't all purebloods have that? Or wait for the water to build...and break down the door." That wasn't her favorite possibility, but this room could only hold so much. "We could send a patronus, but doubt it would send in time..."
