fuck me I think I figured out the haloed hands on the skin spy.
Kellhus is God entangled, which generates the halos.
The Gods cannot perceive the skin spies, unlike sranc which have no consciousness in their brains, the skin spies are "keepers of the inverse fire" and for unknown reasons this makes the gods blind to them.
But what happens when the Gods encounter a skin spy via the perception of other people they are not blind to?
The gods see the person the skin spy is imitating. The gods then automatically "fill in the blank" that the thing they cannot perceive but now perceive via someone they can perceive is in fact obviously of course the thing the person they perceive is perceiving.
In other words, because Serwe can see the-thing-called-kellhus, the gods can see it. The gods can't see it otherwise. But when the gods see the thing-called-kellhus via serwe they suffer an inner contradiction. They know they can perceive kellhus. they know serwe is currently perceiving him, and they know they cannot be wrong. So therefore of course the thing-called-kellhus must be kellhus.
And as a result, halos appear on the skin spy while it is being perceived by serwe, because of the limits of the gods comprehension and their inability to accept they may be in error.
so for a brief moment, the skin spy is also god entangled, as kellhus is, because the gods are idiots.
