Meanwhile, at the back door...

The Superintendent had found that you can get away with a lot if you carry a clipboard and look like you know what you're doing, so had adopted the habit of carrying a folding clipboard in one of her surprisingly roomy pockets. She got it out now and, despite having brightly-coloured underwear showing through the split in her trousers, she walked up to the back door of the large building, and after fiddling for a moment with her Solar Spanner, slipped inside.

The room beyond was dark and had a general air of being backstage, there were wires lying around and discarded boxes, things set down for later use now gathering dust.

"Mysterious energy source?" The Superintendent said quietly and melodically, "Here, little mysterious energy source."

She made her way down a corridor where people were bustling and fussing with tools, lights, garment bags, and she made sure to look intently at her clipboard as she passed them, and occasionally pick a random thing to look at and nod approvingly. After a while she found a staircase with a sign clearly stating 'no entry', which she completely ignored.

At the top of the stairs was a door labelled 'control' and also 'keep out', which she also chose not to pay attention to, and quickly had the door open.

"Camera three, you're off your mark... that's good." Came a voice from inside, and The Superintendent saw three figures sitting at a desk, bathed in blue light from a bank of monitors showing a catwalk, and an expectant audience, a live feed from somewhere below.

"Don't let me interrupt you." The Superintendent said, "Actually, on second thoughts, do."

The three figures turned to look at her and she could see they were not just bathed in blue light, but were in fact blue-skinned.

"Who are you?" One of them demanded.

"Energy inspector." The Superintendent replied, "You're using some weird energy, and it seems to spike whenever someone gets embarrassed, what's that about?"

"Ah, the sweet taste of embarrassment." One of the blue people replied, licking its lips with a forked tongue.

"Sweet taste?" The Superintendent repeated, "Wait, I see. You convert emotion to energy and feed on it."

"We do." One of them nodded, "And tonight we feast." It pressed a button and one of the monitors showed an image of Amy, dressed in a long blue gown and being fussed over by hair and make up people, "Someone you know?"

"She's a friend of mine."

"She isn't who we expected, apparently she got in using an ID stolen from one of our models. But never mind, she will work just as well. In a few minutes she will go out on that catwalk, and when she reaches the end of it her dress will fall apart at the seams! Her humiliation, combined with the amusement of the audience, the people watching at home, the ones who read about it in the paper tomorrow, it will be glorious!"

"I won't let you humiliate my friend!"

"You won't be able to stop us." The alien pressed a switch, and The Superintendent suddenly found herself pulled back against the wall and held there, "Not with the static cling holding your clothes to that wall!"
