At the end, when they are watching the video at the erudite head quaters. It features Amanda Ritter. At the end of the video, she says : "My name will be Edith Prior," .This confused me alot. Prior is also Tris's last name. But..... Her mums name is NOT Edith. It was proven when Tris was under the truth serum. She got asked the question, who are you parents? She then answered: Andrew and Natalie Prior. Who is Edith??
