Jamie discovers the Doctor’s mica clue

Jamie, trapped inside the Dynatrope and searching for an escape route, kicks a small object near the locked exit door. Upon picking it up, he recognizes it as the Doctor’s discarded piece of mica—a tool the Doctor had previously used to manipulate the Krotons’ power source. The discovery suggests the Doctor may have left it intentionally as a clue or a means to interact with the Dynatrope’s mechanisms. For Jamie, this moment is a critical turning point: it confirms the Doctor’s prior presence in this space and hints at a potential solution to their shared predicament. The mica’s properties, likely tied to the Krotons’ crystalline energy, could be the key to disabling the barrier or even sabotaging the Krotons’ power source from within. The event shifts Jamie’s focus from blind escape attempts to strategic problem-solving, aligning his actions with the Doctor’s broader plan to neutralize the Krotons’ threat.
