Minos and his women were in a situation where they basically had to show themselves to the Celestials fighting in that area. But with two sides clearly competing against each other, they couldn't put themselves between the two, at the risk of one of the parties turning against them to prevent them from approaching the other.
The group made their way in discreet defensive formation to the Celestial side of Slapis, having no choice but to enter that side of the border.
But as well as choosing an area to enter, they also needed to work out how to approach the Celestial. High-level Supremes were fighting and the two Celestials in that area seemed to be entertained by the combat. Would it be right for them to approach and interfere with the developing battle? They felt not and decided to approach without getting directly involved in the confrontation and wait for the moment when the two sides would lower the intensity of the confrontation.
