He patted the console slightly, just as the ship started to move. "You better hold on. It tends to be quite the right. Not that this should take us long." However, while holding on to the railing with one had, he also walked over to Billy, once more reaching for his hand and this time inspecting his wrist. "Oh, you'll have quite the story to tell me when we're done here."
