Joshua could sense him, sense that a kind of purposefulness had returned to the ship, even before the ambulant unit joined him on the observation deck, as he drank the first coffee of the day. Sally was evidently still asleep. They were stepping gently, and worlds washed beneath them. As ever the Long Earth was mostly trees and water, silence and monotony. Joshua was glad to be free of the hard-to-pin-down oddness of Happy Landings, but as they headed West once more that gathering pressure in his head had returned. He tried and failed to ignore it. The two of them sat in silence. There was no mention of Lobsang’s departed friends the trolls, or of his offline episode. Joshua couldn’t read Lobsang’s mood. He wondered vaguely if he was lonely without the trolls, disappointed they had chosen to leave, frustrated that his research was evidently unfinished. It was faintly disturbing that Lobsang seemed to be becoming more unstable, more unpredictable. Overloaded by new experiences, perhaps.
