Query: Great episode

This episode is really good, in this episode you get to learn about The Originals and how they became vampires, everything about their family. It's really interesting. The story of how they became vampires is very clear,easy to understand and it all makes sense, whoever the writer is, did an excellent job. If vampires were real the story they made up for this episode seems like a great fit. Most vampire movies/shows never explain where vampires came from...but really good episode
