The Cost of Calling Power
The Dark HalfThad’s growing ability to summon and perceive the sparrows changes from a discovery into a moral burden with consequences he cannot predict.

A Power Recognized

A Power Recognized
Naming ownership
Thad’s automatic writing identifies him as knower and owner of the birds. The words make his connection explicit before he understands its origin.
The risk of possession
Calling the sparrows a power may be another mistake. Thad senses that knowledge and control are not the same thing.
A Secret Kept

A Secret Kept
Concealing the birds
Thad tells Alan details about Stark but withholds the full significance of the sparrows. Alan later notices that the writer is protecting this knowledge.
Unequal understanding
Their alliance depends on partial disclosure. Thad may be hiding the only advantage he has, but secrecy also risks leaving Alan unprepared.
A Tool Without Mastery

A Tool Without Mastery
Summoning with a whistle
Thad carries the bird-call Rawlie gave him and prepares to use it alongside his writing. He knows the method may provoke a force he cannot stop.
Responsibility accepted
He proceeds because Stark has taken his family. The decision is not confidence but a choice to accept danger rather than surrender them.
The Flock Enters

The Flock Enters
A hidden force revealed
Thad writes the birds’ name and blows the whistle. The sparrows gather outside and then break into the house as Stark realizes what is happening.
Protection and destruction
The same force that helps remove Stark also wrecks the home and endangers everyone inside. Its action cannot be neatly separated into rescue and catastrophe.
The Pecking Reminder

The Pecking Reminder
A bird turns on Thad
A sparrow lands on Thad’s shoulder and pecks his face before flying away. The small injury follows the enormous supernatural event.
No ownership guaranteed
The act makes Rawlie’s warning immediate: the guides are not servants. Thad may have been helped, but he has not secured their obedience.
