Stifling a yawn, Donna wandered in the consoled room, stretching her arms as she did so. She found the Doctor manically pressing buttons and pushing random levers, although something seemed a bit...odd. His movements were more rigged and his skin seemed pale and clammy. Before she could say anything, he spoke first, asking her if she had slept well.
