An Unequal Collaboration

Assistant and Manipulator
Pule performs the labor
Narbondo sends Pule on dangerous errands, including grave robbing and the theft of a carp, while reserving the authority and knowledge for himself. Pule believes his work should earn him a share of the discoveries.
Mutual distrust
Narbondo views Pule as useful but replaceable; Pule sees Narbondo as an inferior who takes the credit. Their partnership is held together by ambition rather than loyalty.
The Assistant’s Resentment

Credit and Control
Punishment follows failure
Narbondo berates Pule when the search for the manuscript fails and destroys Pule’s attempted skin treatment. Pule experiences this as proof that the doctor intends to exploit and discard him.
Revenge takes form
Pule’s anger grows into a plan to attack Narbondo with a bomb. He no longer seeks merely to share the doctor’s power; he wants to destroy the man who has kept him subordinate.
A Failed Bombing

The Revolt Is Foiled
A bomb in the passage
Pule carries a lit bomb into the hidden passage near Narbondo’s laboratory. Kraken attacks him, and Hasbro throws the device down the stairs before it explodes.
Narbondo escapes again
Pule fails to kill his former master, while Narbondo flees over the rooftops. Their conflict ends not in a decisive victory but in mutual ruin and another unresolved pursuit.
