i thought the names on the ground might be the names of the Termites themselves, the "inner circle", those who belong to the cult like thing they got going.
with the reminders at the wall i imagine they need to practice some sort of brainwashing on themselves to keep up their spirits for it being OK being cannibals.
i was wondering already why it took the show so long to bring up the subject of cannibalism, comparing the bleakness of the situation to the movie "The Road" on times. but then it sure is a nice step up of the story getting worse and worse all the time.
however those who resorted to cannibalism in The Road seemed very ******** up people while the Termites here seem to keep up a happy healthy image, they must be brainwashing themselves in order to be like that.
