One thing the Godly Creatures had was their ability to detect their surroundings, just like Spiritual, Divine, or Celestial Sense. The difference is that they can perceive the presence of beings that don't emit Godly Pressure.
As mentioned before, that's one of the ways they use to identify each other. So, when Fonken noticed the shadow, and it got close enough for him to see it was Roan, he got puzzled. How did Roan get so close to the Godly Predator, and the Predator failed to notice him?
The answer was the same one as before: Roan used their cultivation technique in reverse to emit their own Godly Pressure. He went even further this time. The amount he was emitting was so low that Roan looked more like part of the environment. Fonken, who was just there, didn't notice Roan was also emitting it.
