On this episode, Yona waits for Hak to recover. Later, the priest tells them a legend and their revealed goal.
So it was nice to see Yona learning more on some things while Hak was recovering. Also the legend and plot details mentioned got the story way more interesting. Now will Yona and Hak be able to start their journey on the next episode or will they train first? Overall, nice build for the main plot.
Conclusion: Nice build up for the main plot.
