Meeting Keiko upon her return from Bajor, O'Brien is shocked when his wife says, in her own voice, that she is really an entity that has taken possession of Keiko's body and is holding her hostage. She states that O'Brien must reconfigure some communication and sensor relays on the station or Keiko will be killed, and sends Keiko into a convulsion to prove her point. Seeing no other alternative, O'Brien is forced to obey the entity's demands.
