ABOUT THIS SERIES:Tanzila and I started to wonder which factions the characters would belong to, and I came up with a spreadsheet filled with all the characters, the faction they would have been born into, and the faction they would have chosen in the end. Funnily enough, it all worked out (almost) perfectly. Please note that this sorting is tied to our understanding of the characters and may not be the most accurate.
LET’S GET META: Felicity is Candor-born because she tends to say whatever crosses her mind without thinking it through, and the “filternessless” is a typical Candor trait. Dig is Abnegation-born because he cares about the well-being of others to the point of putting himself in danger for them. But at the same time he’s a soldier, therefore the Dauntless transfer. Roy seems pretty obvious to me, and Sara and Oliver will be explained in the (respectively) Lance and Queen families posts. [EDIT: I changed Sara. Orange is Amity.]
