Sam walked over to the Dwarf who had taken their attention. Approaching him, he could see the glow that overlay the tatterdemalion image and knew, he didn’t know how, that the Dwarf was healthy. His aura didn’t have the "smell" of the noodle vendor and there was no taint to the color that would have been present if the Dwarf was the substance-abuser he pretended. Even more than Ghost, this person’s glow was blotched and crisscrossed with dark, dead places- the marks, Sam realized, of extensive cybernetic enhancements.
