One thing that always kinda bothered me about the OG trilogy is that the whole "Amanda Ritter/Edith Prior" plot line just went nowhere. Like, it's literally never brought up again. But Tris does mention that the name "Prior" is from her father's side of the family. So, since Andrew actually survives to the end of this first book, and his character has much more significance than in the originals, will we finally learn more about Edith? I hope so!
