Yuna doesn’t have the conviction to kill someone.
Warning: Spoilers ahead!
To start, Soo-Woon is talking to his number one henchman about taxes and corruption of the kingdom. Yes, King Il is a very kind man but because of this trait, people in their government abused the power that they were given to them.
As the group of Hak, Yun and Yona travelled thru the mountains as instructed by Ik-su, they are very careful in passing by both the capital city and the Fire Tribe’s village. Hak left the two behind for a mean time to buy a bow and arrow, as he has lost his when they fell on the cliff.
Wanting to protect Hak from dying, Yona had the resolve into trying to learn swordsmanship. However, Hak gave her the bow and arrow instead, as he is fighting in the front line, while she can be the support.
Agreeing, Yona trained night and day while they travel thru the mountains. Whatever she kills became their food for the trip. Yun praises Yona’s determination and improvement in terms of wielding the bow, however, he noted that the princess lack the intention to kill. This will not bode well in battle and informing her that the only way to survive is to kill.
One day, Yona saw a small boar grazing around the forest and she tried to shoot at it to see if she can kill it. Of course she missed and Hak asked Yun to go ahead without them. To test her, Hak asked Yona to shoot at him but every arrow missed him. To stir her anger, Hak told her to imagine him as Soo-Woon — which effectively grazed his cheek. It was like a clarification that Yona hates Soo-Woon and if the time comes, she can fight for what is right.
Following Yun in the forest, they were assaulted by mists which reminded Hak of Ik-su’s saying about the village surrounding by mists. A warning was aired out all over them, asking them to go. The assailants were amazed that in one swing, Hak was able to clear the mists and reveal that all arrows are pointed at them. As they discussed their fate, the leader of the group noticed Yona’s red hair and kneeled down in front of her, as if they were waiting for her to come.
To confirm what they need to know, they are at the edge of the village where the first dragon is staying and everyone is its protector.
In this episode, Yona was trying to retain whatever teaching her father had taught her, especially about the weapons. And yet, in this situation, she needs to learn because she wants to protect Hak. Yona is such a tease but she’s naive not to know that Hak loves her.
