The powerful bad guy goes to the surface to destroy the world , and two of her friends get there . They get her out of the water and somehow manage to get her heart beating again , which , without electricity , is quite a miracle . So she wakes up , feels even stronger than before and goes back out with her friends . On the surface , she fights against the powerful bad guy and kills him which , tangentially , saves the world . I understand the need of saving the world , because people usually do n't really like it when the world gets destroyed , and if the world did get destroyed at the end of the first season it would be a little hard to make a season two .
Question: What may be the reason for their discussion about the show ?
The answer to the above question:


They are getting ready to watch the second season .
