Object
Charing Cross Explosives Detonator (and Ammo)
A compact detonator and its associated ammunition used in the Charing Cross underground platform during the Yeti crisis. Arnold and Blake inspect the device after it was fired but failed to detonate the explosives crates, confirming sabotage. The detonator's failure—with the button pressed and circuit complete—sparked Arnold's accusation against the Doctor. Later, in the Goodge Street ops room, Arnold brandishes the detonator (and references the inert ammo) to expose betrayal within the unit fighting the Yeti outbreak. The device's sabotage is tied to the Great Intelligence's scheme and fractures alliances amid the crisis.
