Singletsona

undefined:

A singletsona is a personality that is put on by a system to pass as a singlet. In some cases this personality might correspond to a specific headmate like the host, core, or main, but it may also be a fabricated personality or other source. Typically, members of the system have to pretend to be this personality to avoid outing their system to family members, friends, coworkers, or others. This is different from the host switching in to take over in such situations.
