Of course, nothing bad really happened. The injured guy was merely having stupid speculations but actually, Wendy was not really harmful. The girl might be quite headstrong, and with a very firm heart, but in the end, she was still only a regular non-host, and a weak, fragile, beautiful woman.
Despite Wendy appearing like a psycho due to the scary words she's been saying, in reality, she was just actually bored and at the same time angry at herself for bringing such trouble home. However, if truly thought more carefully, she was saner and righteous than anyone else in the world.
But of course, her righteousness was something shaped and molded by her environment and upbringing as a girl from a family of police officers.
