The Double-Crossing Ally

Imagine a scenario where one of the trusted members of a treasure hunting team is secretly working with their adversaries.

This creates an atmosphere charged with betrayals, distrust, and high stakes, as the group has to be on guard both outside and within. Consider how the reveal unravels, the dynamics when suspicion creeps in, the climax when the double-crossing is exposed, and how relationships are tested and evolve over time.
