I consider this Silas' bad day. Even Rose's penchant for perfection doesn't ensure peace between Gath and Gilboa.
Rose: "We can change the world today so long as we provide perfection."
I believe it starts when Silas orders Abner to kill David. Silas' day turns for the worst once David is invited to the peace treaty talks. David couldn't keep his mouth shut during the luncheon but at least the Gath official was pleased with his answers. David is still full of optimism despite his mother's warning about the nature of politics. Speaking of his mother, she tells Michelle something that screams foreshadowing:
Jessie: "People with destinies, things don't go well for them. They die old and unhappy or young and unfinished."
Back to the treaty, it falls apart after the luncheon and the blame lands on David because he tries to stop the Gath officials from backing out. Silas has to deal with the consequences of the failed peace talks in addition to a problem with the treasury courtesy of William when he executes his threat in the previous episode.

Another Benjamin also has a bad day. Jack is shut out of the luncheon because of David's invitation. He reacts by inviting his buddies to go on an exorbitant shopping spree since he has access to Gilboa's treasury. I love the way he says this: "My card's been declined. Uh oh, I hope there's no problem with the treasury."
Silas solves the problem with the treasury by talking to an imprisoned former ruler in Gehenna. Abbadon used to rule half of the present kingdom of Gilboa. Their conversation is my favorite of the episode. Silas uses his great manipulative skills by showing Abbadon a picture of a woman to get what he wants. I have a suspicion the woman is Michelle. Queen Rose also tries to solve the treasury problem. She visits William and reminds him that there can be a chance for his exiled son to return. The queen and king are perfectly matched.

A new mystery crops up from a conversation between Silas and Michelle. The topic of their talk is David. He reminds Michelle of her vow which she insisted he witness. By the end of the episode, she ignores David.

As for David's assassination, I like how it's resolved. His escape from death cements that he is blessed. He doesn't even know that his life was in danger or that those two guards may have helped save his life. I should pay more attention because the scenes with the guards and the pigeons seem inconsequential but they actually have an important impact in the story. Another recurring aspect is the "Don't go" messages David keeps noticing. It easily pertains to his assassination but has a very different meaning to him.
