Khan spares no glance for the other patrons - let them assume that the good doctor talked him down, that everything was some sort of accident brought on by the panic of being suddenly translocated. There's no false smile on his part, but he does follow.

Although 'follow' may be too loose a word for the way Khan moves - it's much more of a prowl. He keeps Julian firmly in his sights, but isn't shy about mapping what he can see of the ship, noting the corridors and rooms, deck maps and Jefferies tubes. With each additional scrap of data, his escape options grow.
