Best friends?

Stefan and Elena are best friends since kindergarten. When Stefan and Damon go on a 3 day trip to Las Vegas to have some fun for Damons birthday, Elena's parents die in a car accident. She's been trying to reach Stefan all day long, but she only gets his voicemail. She's mad at him. When Stefan comes back and sees many missed calls from Elena he gets worried and goes to her house. What will happen between them? ♥
