HAHA anyone who guess Denise, Elizabeth, or Alexander is WRONG. It actually is Evan 💖💖 and yk what, he HATES Erwin for it. For "leaving everyone." Lmfao he actually did die at first but he got revived and was hospitalized for two weeks. When Erwin finally had a chance to visit him, he had nothing but resentment for her. She lost everyone on that one day, even the person who survived. 

Evan's words haunt her every day, and she does in fact blame herself for not being able to help closer to home. She blames herself so much. Erwin has nightmares about it. About Evan, about Joseph. About her whole family. She let them down. :3
