Damn this is tragic. Yu-hon’s extremism twisted his love for Yonhi and brought all these tragedies. He was paranoid about the priests because he was overprotective of her identity when it meant absolutely nothing in the long run.
It’s sad that Hashi likely expected all of this to happen. Fuck the maid for her good memory and loose lips. Yu-hon was never supposed to know that Yona was the incarnation of the Crimson Dragon King. He funneled all of his hatred for Yonhi’s bloodline/curse onto his niece. A CHILD. 
Fuck Yu-hon, honestly. He was aiming for Yona in that carriage and killed Hashi instead. Il definitely killed Yu-hon after he found out his brother was trying to kill his daughter. Poor Yonhi and Soo-won for being caught up in all of this.
This whole situation sucks because Yonhi genuinely liked her sister-in-law. She must be carrying this guilt for Hashi AND her husband’s death, because all the tragedies happened due to her identity. Can’t wait to meet her in the present. Hard to believe she’s survived this long with the curse, guilt, and loneliness.
