The sound of a shout clearly meant to garner attention startled Darcy. She gasped and raised a hand to her chest, slowly letting it fall back down to rest on her protruding stomach as she willed herself to calm. In the back of her mind, she was appraising the owner of the voice. Her best guess was early to mid-twenties, working poor, and either brains or brawn but likely not both. She dismissed him as a potential mate nearly immediately which left her able to talk to him with indifference toward attempting to put on a show. Instead, she was able to focus on the task at hand. ...though, if he was college-aged still, a little charm wouldn't hurt and it might even help to make her situation a focus. If he worked here, he could help get her back home to Ethan before it was unhealthy for the twins to travel.
So, Darcy put on her best helpless, sheepish, and confused female expression and let out a soft sigh of relief. "Could be better," she replied honestly. "Um, how would one go about getting home...? You see, there's been a mix-up here. Neither of us mean to be here." With that, Darcy gestured vaguely at Jack.
Then, she went on. "I personally did not offer to be part of any sort of study. As you can see," she said smoothly, rubbing her baby bump and thinking to herself that, for the first time since she'd split with Marcus, these babies might work to her advantage rather than ruin her life, "I'm in no state to be poked and prodded unnecessarily. I really would just like to get back to London and gestate with the least amount of stress possible, so...if you could help us, it would be very much appreciated." She gave the younger man a small, possibly slightly flirtatious smile, hope shining in her eyes.
