I've already sort of given up on using that timeline I mentioned, because this needs to follow directly on from the previous story.
A dark-haired young woman fell out of the door to the club, hooting with laughter. As she took a drag from the cigarette dangling from her fingers, her friend emerged from the door and followed her. Strains of the music drifted after them as they made their drunken, unsteady way down the street. They stumbled in the general direction of the river, laughing and falling against each other.
"Look, watch me!" the dark-haired woman cried to her friend. She meandered onto the bridge and hauled herself up the railings, cackling and sucking in breaths of her cigarette. After clambering over the barrier, the woman threw out her arms and shouted, "I'm flying!" and let herself fall headfirst down, down, down; until, with a splash, she hit the water below.
Her friend waited a few seconds for the woman to surface. When nobody appeared she wandered away, still chuckling to herself as tendrils of smoke escaped her nostrils and curled around her head like vengeful snakes.
