"We could always try," Su murmured, attempting to focus even though she kept getting distracted by his lips. "Einstein had a theory that time and space form a continuum which twists and folds and bends from the point of view of someone watching it, relative to influences like gravity and movement, of course. If it could be affected by influences like gravity or even weight, perhaps if we focused hard enough, in theory using our thoughts as a sort of gravitational pull in their own right, we could create a fold in time that would bend us back to earlier? Although that might create some sort of weird space-time paradox."
She'd gotten off track, going off on one of her 'nerd tangents'. She had a feeling Kevin wouldn't mind at all, though. Merlin knew she didn't mind when he did it. Focusing her brain in a new direction, she kissed him yet again, this time giving in to the urge to let her fingers brush through his sleep-mussed hair. "No. No leaving." Then she grinned. "Double the body heat, double the maintenance level?"
