Jun was staring at Jennie and realized that the girl was trembling. He has no clue on what she's thinking right now.
He tried placing himself on her situation. On the way to school, the car she was on crashed and she fell unconscious. When she woke up, people told her that her brother died and now the world has change. She probably hasn't accepted the reality and most probably still denying the possibility, but was losing hope everyday.
Then, she met someone who looked exactly like her brother. She probably thought that these people were lying to her and now being reminded and proven that that person is different from his brother, she finally accepted the truth.
Jun ignored her and faced Chairman Sarah instead.
"How did you defend this place?" said Jun, "This place is huge and from what I saw, your tanod's weren't properly armed."
Chairman Sarah drank some water before answering his question.
