Hiding the lines...
A 'line' motif runs through many of the associated symbols in the area of Scorpio 22. Scorpio 21, "A soldier derelict in duty" suggests a refusal, or an failure to step up to the line. Scorpio 23 "Hunters starting out for ducks" introduces the theme of camouflage and hunting blinds.
The idea is to disguise where the line is drawn. The ducks, not seeing the hunters hiding, think their pond a safe place to land. The hunters deliberately obscure the line that leaves them sight unseen while their quarry draws near.
You can imagine that if a soldier has refused orders, he might want to hide for a while in the hopes of not being found. Perhaps one would attempt to blend in with the crowd in order to escape detection.
All of these themes are alive and well in Scorpio 22. The key is to recognize an awareness of line issues, those that divide sensibilities and values, then to assess which side of the line you are in.
