The last time Edith had cried like this, she was sixteen years old. At that time, Mike was dispatched to investigate a kidnapping case. Some rich man's daughter was kidnapped and they believed that the girl was brought to Z Town to hide.
Mike and his team finally found out the whereabouts of the kidnappers. They were going to rescue the girl when one of the kidnappers took out a gun and shot.
When Edith heard that her grandfather was shot, she was stunned and was unable to respond. It was only when she had seen her grandfather again that she started to bawl.
She had lost her mother in a car accident and hearing from those uncles that her grandfather might not survive turned her dazed.
It was only when her grandfather was awakened that Edith was able to react.
