Six learns that the man he knows as Two is only the latest in a series of Two's, and that there is no One nor has there ever been. This rank is to show that even Two is a public servant. Upon a surprise request, Six agrees to work undercover for Two in a cell with 909. They are unaware of any of the other cells, meaning that everyone is possibly working undercover for Two in some capacity. Six is up front in that he is only taking this role to target Two. Six and 909's task is to watch 1955, a teacher who is suspected of being a dreamer. With 1955 being a teacher, Six goes undercover as a teacher himself, his class on surveillance. Six uses this role in an unusual way for his own benefit. Also in his undercover work, Six learns more about others in The Village, including 909, 11-12 and 313, the latter who has a love-hate relationship with Six. Meanwhile, Six remembers more about Lucy, the reason she approached him and her connection to Summakor. And the sleeping woman in Palais Two awakens. She is Two's wife, M2.
