How characters are introduced

Ruby is the first character to be introduced. She is presented as a stereotypical 17 year old girl. She appears to be quite, passive and innocent. The first shot is Ruby as she puts on her makeup. 

Larry is disturbing from the beginning. He dresses normally, and appears to have a normal house. However once his "Den" setting is introduced, he is obviously the protagonist. The den is dirty and cluttered, with pictures of girls scattered across his table, including one of Ruby.
