The episode opens up with Lydia in a study room reading a book when Edgar (the Earl) walks in and says that Paul (from previous episode) still can't get the ring off and is wondering about the water horse(Kelpie). Edgar asks if Cain is a real fairy and Lydia says yes but an evil one known as a man-eating Unseelie Court. Another fairy (Sweetpea) comes in looking for Marigold. Sweetpea finds out that the ring is on Paul and says that the Fairy Queen will just marry him the. Kelpie come in and say he is going to give the ring to Lydia or he will eat them. Edgar has Paul make a painting using Lydia as a model. Paul tells Lydia of a boy who resembled the Earl, and that that was the person who made him realize that he loved drawing. Lydia finds out over dinner that Edgar was the little boy. Kelpie interrupts their meal and Edgar makes Kelpie eat a liver which is like poison to aquatic horses, sending Kelpie off. Edgar later confesses that he like Lydia and she doesn't believe him. Paul attempts to poison Edgar but then stops Edgar before he drinks it. Edgar is stabbed by someone else with a knife covered in a snake-like poison. (thetvdb.com)
