S1·E13 Echoing Fear

The blue dragon warrior, who experienced a voice telling him to protect Hiryuu when he touched Yona, while recognizing Ki-Ja as the white dragon, is dazed and escapes into the caves. Yona and Yun enter the caves, leaving Hak and Ki-Ja behind to deal with the villagers. They find the agitated blue dragon warrior, and Yona calmly asks him to be her ally. The blue dragon warrior tells her to leave, and they return to Ki-Ja who is holding back the hostile villagers. An earthquake traps the villagers with Yona, Ki-Ja and Yun. A villager explains the curse, until the blue dragon warrior enters. Out of fear, the villager strikes the blue dragon warrior, knocking off his mask.
