I think that this is absolutely my favorite episode thus far. In this episode, the fae are celebrating lashochain, which is apparently the most holy day of the year. In honour of the holiday, fae are not allowed to use their powers, do any form of violence, or feed. It is the one day of the year when light and dark can come together. Apparently during the WWII the German Fae and the French Fae put down their arms and celebrated the day together.
Bo and Kenzie go to the bar to get a drink when suddenly, a woman stands and releases and earth shattering scream. Trick stands up and announces that the party is over and says everyone but members of the five families has to leave. Bo asks Trick who the five families are, and he tells her that there are five royal families, 5 human and five fae. The banshee scream indicates that someone from the family is going to die, because banshees only scream for them.
Trick calls Dyson to investigate who the Banshee screamed for, and Dyson asks Bo to accompany him because he is not allowed to use his powers today and since she does not know her parental heritage, Bo could in fact be royal herself. Bo asks Kenzi to come along, but she chooses to stay behind and eat. Before Bo and Dyson leave, he follows Trick to his office to find him packing a bag. When Dyson asks who he is packing for, Trick tells him that he is packing Lou Ann's things, and that she is on the run after he helped her. Dyson is shocked and wants to know why he helped Lou Ann, considering that she is dark fae. Trick responds that Lou Ann was the midwife at Bo's birth, which means that Siegfried was telling the truth when he said that Lou Ann knew something about Bo's mother. What is even more shocking is that Trick and Dyson both know about Bo's parentage, but when Dyson asks how long they are going to avoid telling Bo, Trick tells him that they will avoid it for as long as they can. This of course causes Dyson to ask what they are going to do if Eve, Bo's mother comes looking for her daughter and Trick tells him it's not if but a when, and that when the day occurs, a reckoning will have to happen. Since Bo's mother's midwife is a dark fae, I wonder if this means that Bo's family are dark fae? The two sides are not really allowed to interact and does not make sense to have a dark fae midwife and a white fae mother in labor.
Dyson and Bo track the banshee to her agents office. They tie her to a chair and force feed her ground up liver. Apparently, banshees react terribly to iron and this forces her to reveal who the prediction was for. She tells Bo and Dyson that the prediction was for Sean of the royal family Kavanaugh.
Back at the bar, Sean and Kenzi are hanging out and getting to know each other. He won't reveal exactly what kind of fae he is, but tells her that he is really good with money and does accounting work. Shortly after he reveals his talents, Dyson and Bo come back to the bar and announce that the banshee predicted Sean's death. He tells Bo that his one wish before he dies is to make peace with his brother Liam, who has sworn allegiance to the dark fae.
Bo and Kenzi go off in search of Liam and Sean and Kenzi steal a car so that Sean can say goodbye to his father. When they arrive, Patrick Kavanaugh is all business with his son and tells him that he has to get his affairs in order, so that he won't leave a mess behind for others to deal with. Sean says that this is not the way he wants to spend his final day, and that he has spent his entire life living up to his wishes. Sean walks out and Kenzi stays behind a moment. She picks up the newspaper and notices that Patrick was looking at the horses running in today's race, and gives him a tip about the horse that he has chosen.
At Liam's office, they watch as an investor is being dragged out begging for Liam to return his money. It seems that Liam makes his living running scams, stealing people's life savings. When Bo tells Liam that his brother is going to die, he says that he does not care, and that he deserves to die for what he did to him.
