The lady is recognized by Bai Qian to be Xuan Nu, the Demon Clan's Queen and a shapeshifter. Xuan Nu runs away, only for a man to come running to the boy, calling him Ah Li. Bai Qian, thinking that he is Xuan Nu, tries to stop him from approaching the Ah Li. While fighting, the man stops and calls her Su Su.
