Fronting

Fronting is an activity performed by one or more headmates, where they take control of the body and handle daily activities and communication. This can often include allowing other headmates to speak via internal communication.

In some cases it's possible for no-one to be fronting, in which case some type of default behavior takes over the body. This can surface in multiple ways, such as becoming unresponsive.
