Zach's smile didn't fade, but his eyebrows raised just a little.
"I'm sure our Honoured Guest can speak for herself. Rest assured I don't mean to pry. In the mean time, on the subject of 'doing my job'...
While we've been speaking I've been constantly monitoring several different factors that allow me to determine and assess risk. The direction of the wind, the positioning of the Sun, and the areas of most cloud cover, all come together to tell me where a threat will most likely come from. By listening very carefully, and by looking out for small, anomalous vortexes within cloud formations, I can be warned of the turning prop blades of a encroaching vessel before I can actually see it. By listening out for the beats, inflation of deflation of its gas bags, and feeling the wind speed and direction, I can even tell you, roughly I admit, how fast it's going, in what direction, and whether it's gaining or losing altitude. Some might even say that asking questions is another part of my job. I four Honoured Guest is ever inclined to tell me who's pursuing her, I may be able to take measures to better prepare myself and others to detect and defend against them if necessary, thereby protecting this ship.
Now, it's true that I could still do all these things from up in the Crow's Nest, but consider... in the unlikely event that we're being hunted by someone talented enough to evade the gaze of both Oswin and myself, their top priority would be to take out the ship's eyes and ears, which also happen to be my eyes and ears, before anyone else knew what was going on. The first place they'd look for such a person would be up in the Crow's Nest. Down here, the ship's eyes and ears are inconspicuous.
It's quite fascinating really, that a lowly grunt like me can do all this, while you yourself do such a good job of remaining standing whilst holding on to a very large wheel."
Zach had lost interest by this point of proving himself to Beth, and realised that any conscious effort on his part would likely be a self-defeating prophecy anyway. However, at the same time, obeying direct orders from her did not mean he was going to be patronised.
"I already advised you to alter our course Captain. You either pay attention to how I conduct my duties, or you don't. It's none of my concern, and, as Captain, it is of course your right to ignore everything I say and do if you so choose. Just so we're clear though, you never need to worry about my ability to do my job."
With that, he gave another courteous bow to their foreign guest, and went to see who else was about on deck.
