Just as you do most nights, you lay in bed in total darkness letting your imagination run wild. You fantasise about her; Margot. She is perfect, absolutely stunning, from head to toe, every orifice to appendage — at least, you imagine. And so you drift off to sleep with Margot on your mind. You'd usually hope that these thoughts would linger into your sleep and influence your dreams and most nights proved that to be wishful thinking, but not tonight.
"Jack!" You're startled awake by the call of your name, a man's voice ordering you up. Immediately, you notice your surroundings have changed; you're no longer in your room nor in bed but amongst a pile of coats in a cupboard or cloakroom. "No wonder," the man says, "I expect better on a production like this." You're still a little out of it. "We need all hands on deck today, I expect you to prove your worth. Anyone can be a runner, you're replaceable, you hear me?" Instinctually, you say, "Yes, okay." And the man leaves, shaking his head as he goes.
You bring yourself to your feet and notice a lanyard hanging from your neck. Bright orange, lists your name and says that you're a runner (which basically just means that you're an extra hand tasked with doing whatever may offhandedly need doing). After wading through the coats, you peek through the door to see tens to hundreds of people rushing around on what appears to be a film set. Then you notice that the film set is almost entirely hot pink, which can only mean one thing. This is the set of Barbie, the film based on the toy-line of the same name.
And, if this is the set of Barbie, then that too can only mean one thing, Margot is here. Finally, it worked. All those nights spent fantasising have paid off. Not long after coming to such a thrilling realisation, come the booms. You feel the ground shake, the coat hangers rattle against the railings beside you, and then you see her. Margot is here, and she is enormous. She's wearing casual attire: trainers, socks, shorts, and a sweater. Escorted by several regular-sized people at her feet, she takes massive, wading steps through the set, presumably on the way to her trailer. Naturally, everybody gawks at her as she goes but nobody more than you. Truly, she was now embodying her godly status.
"Psst!" You hear from one of her escorts who had managed to notice you. They gesture for you to come over and so you do; you don't have to think twice. You join the band of little people trailing the Goddess of a woman and can't unglue your eyes from the sight of her. You were about up to her knees in terms of height. Your entire head would fit within her hand. Her foot alone was the size of your torso; should she step on you with her full weight, you would almost certainly die — but what better way would there be to go? You ask the person who called you over "What's going on?" to which they explain that Margot has been embiggened for the sake of a scene that will, at the very least, be included in the film's first trailer.
Eventually, you and the troop arrive with Margot at her trailer, which in actuality was a warehouse that had been furnished accordingly, at which point you're all told split up and told do complete different tasks.
1) You're told to fetch Margot's costume (and help her into it).
2) Margot picks you out in particular (but probably at random) to stick around and be of use to her in her trailer.
3) Something else.
