Re: Things we have learned so far
Although the phrase had originally been meant for someone else, 'being seen and not heard' also applied to bodyguards. You wanted the 'enemy' to see you but the person you were guarding didn't really want to know you were there... at least not until the frap hit the rotary oscillator. Of course, it was your job to see that it never got to that point but that often involved a level of intel that was beyond your resources.
So he dutifully followed the Count around. If the Count crawled into the inner workings of the ship, then Jones crawled in with him... or after him... if there was room.
Once a day, though, Jones made it a point to check out the ship's lockers to see what had been added. Once the ship was in jump, that wouldn't be necessary, but he liked knowing what resources (i.e. weapons) were available just in case things went pear-shaped.
He did his best not to get under foot, but sometimes that was unavoidable, like when the Count changed his mind in mid-stride and suddenly whirled around to go back the way he came. It was at those times that the Count was actually reminded that he had a bodyguard; the rest of the time, he seemed oblivious to Jones' presence. But, then again, that was the way it was supposed to be.
