Final answer:
Without direct references to Colonel Tavington and the colonial captain, it is difficult to determine the specific causes of distrust. The reasons might include fears of insubordination, abolitionist influences, or differing loyalties shaped by the historical context.
Step-by-step explanation:
The question seems to be derived from a historical fiction context, concerning a colonial captain and his distrust by Colonel Tavington. The texts provided reference different incidents involving distrust or tension between colonists and leadership figures, such as the handling of slaves, insubordinate captains in a colony, or reactions to potential emancipation.
However, without a direct reference to Colonel Tavington and a specific colonial captain, it is challenging to pinpoint the exact causes of distrust. If the characters are from a fictional narrative, the distrust could stem from multiple historical reasons, including fears of insubordination, abolitionist influences, or differing loyalties due to the complex social and military relationships of the time.
