Lauren hasn't been sleeping. She's too excited to sleep. The effects of the serum were, quite honestly, amazing. Her eyes had become little sponges, soaking up anything and everything around her. She had spent the night scouring her room, drinking in every little detail. She knew the composition of her desk, the inner workings of her computer, the wavelength of the light coming from her nightlight.
She also knew that she had less then three hours left until the serum wore off. That bothered her. And it bothered her that it bothered her. She had lived her entire life without this. There was no reason that she couldn't go back to living that way. But at the same time, she remembered what it was like when Simon had given her the vitamins. The fog, as if she couldn't see clearly. That's what normal life would be like now. And she didn't want to live like that.
She gets dressed, unconsciously choosing a rather muted outfit. Two hours before school started? Plenty of time for negotiations. She jumps from her window, landing neatly with a roll she had learned last night, and begins to walk back to the lab.
