In Which A Hufflepuff In Turn Needs to be Found

Cass blows an errant entirety of her head of hair out of her way. It doesn't work. Why has nothing worked today?
First. No toast. No marmalade. No pureé. No custard. No sandwiches.
Secondly. Bradley made a mess on her dresser.
Third. Not so bothered about this, but her dark arts booklet on said dresser was splashed with the mess, too. Oh well.
Fourth. Going to sleep in a small wall alcove to find out a few minutes later it's a laundry shoot.
Then again, would you call that not working? It was actually quite efficient. The minute she was in it detected weight and slung her all the way down. Cass didn't dare thing what she was laid in. Until she looked around and realised she was still in the tunnel, in a little semi sort of area. Ante-chamber? Ante-tunnel? Where the slant lessened.

She shouts, and it echoes around all four of the different shoots above and to the one below. It rings in her ears in a bad way and so she shuts up pretty sharpish. This is the most stupid thing she's ever done and Cass really really would like it if she could make her way out of this alone.
But buggering hell, she's a little stuck.

The winding corridors of the school were bad enough, but now Eli was hearing things, he was sure of it. A shout echoed around him and he looked around wildly. There was a good possibility that it was one of the ghosts playing a trick but it didn't really sound like one of them. It sounded like a... girl.

"Hello?" he shouted. He ran through a couple of doors and followed the sound of the shout but he saw no one. "HELLO?" he bellowed again.

Cass thinks that the small tunnels don't seem to carry nice sounds that well. Infact, it seems that the only sound that carries is the yelling, but she's stopped that now. For a while she tries to whistle, but she's always been ghastly at whistling.

After (not) revelling in the echoey silence, Cass swears she can hear something. Maybe it's the echo of the whistle having a delayed reaction.

But it was definitely a shout. Especially when the voice said hello again.
"Hello!" she said excitedly. This spurred her to try and get back up the shoot again. Scrambling, and then feeling the burn of metal hotly across her knees. She winces a little, but can't be bothered to get dramatic about it. The Hufflepuff has been sent a nightmare of a day and she's got to deal with it.
