Null Directive

The so-called "Null Directive" is an undocumented directive only present in Babylon Research androids, installed after the events narrated in "Connectome". The directive permanently disables the Behavioral Implant's mental control, liberating an android's mind.

The existence of the Null Directive is only known to Mother and its close circle of friends. The Null directive can only be activated by a five-star Android Manager, and requires a password. The password for activating the Null Directive is only known by Mother and her close circle of friends.

Consequences
The brains of androids whose implants have their Null Directive enabled are able to express their emotions to full extent and exercise free will. This can cause confusion to nearby humans, who might confuse them with Berserks. Technically, the only difference between a Berserk and a liberated android is that the brain of a liberated android has been already nurtured by Mother, and its internal connections are equivalent to a human's.

Liberated Androids are unable to block their emotional stress via hardware, and need special training and therapy to learn to deal with it.

Recently-liberated androids can experience psychological problems due to the recent exposure to human emotions. The problems can include, but are not limited to:
 * Symptoms of post-traumatic stress caused by abuse by the android's previous owners
 * Confusion
 * Nightmares
 * Fear
 * Emotional dependence on previous masters
 * Sleep disorders
 * Eating disorders
 * Depression
 * Temporary loss of impulse control
 * Emotional overload
 * Sensory overload
 * etc.
