Fortunately, the hypnosis was completely successful and Sarah manages to find the top secret lab based solely on auditory clues, like "it rains, every day," as Sarah pulls up by a field just as sprinklers come on, spattering her truck. So ANYWAY, she finds this big windowless warehouse and loads up her knapsack with guns and bombs. And despite this place supposedly being intensely private, Sarah thinks it's a great idea to just stroll right up to the door HOLDING A GUN. Oh well. At least we're finally getting to the fireworks factory.
And inside there's a single guy working at a desk. He's somewhat surprised, to put it mildly, to have a gun pulled on him. He says his name is Winston, and claims to install air-conditioning. He pleads with Sarah, saying he's got a wife and son. Sarah asks him what's in the warehouse, and Winston says his boss rents it to another company. Just as Sarah's distracted, ol' Winston with the wife and kid whips out a gun and shoots Sarah in the leg. Instead of staying where he is to finish her off, he comes over to stand right over her, and Sarah manages to wrestle his gun around and shoot him instead. He collapses on top of her and rolls off, and Sarah drags herself towards the door, hallucinating her tanktop self spinning a knife, and her pink-dressed self.
Hauling herself out the door, she rolls onto her back and stares into the sun, which isn't going to help matters. Slowly, the sun is blocked out by the descending underside of a craft that looks remarkably like the diagrams from Allan's trailer. Sarah might not have actually seen one, but to me it looks like a Hunter-Killer.
