Edith recalled that ill-fated night of the incident. All the emotions that she felt at that moment returned to her in waves, hitting her all over again. She wished she didn't have to see it again because it felt like reliving a nightmare, but she braced herself for it. It was something that she could never unsee, and the pain would always be there.
While Evans just focused on what she showed him. Her emotions also got in the way, but he was better at handling it than she was. Maybe it was because he no longer considered himself as one of them, but he couldn't say he was completely immune to the pain of watching his own kind murdered.
Once it was all over, they opened their eyes and pulled their hands back. While Evans looked composed, Edith clenched her fists, her rage visible to eyes.
