Bigon's Personality Box

A small, hand-held device of polished metal and etched Urbankan glyphs, its hinged lid concealing crystalline circuitry that pulses with faint energy when manipulated. The Doctor and Lin Futu handle it with care, their voices low as they discuss re-circuiting Bigon without Monarch's notice. Its compact form belies its critical role—the only means to restore coherence to Bigon's fractured android consciousness, a fact the Doctor exploits to manipulate Lin Futu into defying Monarch.
