Episode 15: The Omashu Queen

Ishiko, Rishi, Jax, and Kit enter battle with a group of Crystal Guard who caught them in the throneroom, while Lily defends her master, the Donya. The Crystalbenders manage to injure the team, sending a hail of Jennamite towards the group.
Meanwhile, Rishi lets Tomomi and Satomi into the palace through the servant's quarters. Zhuan, still posing as Fengyu, who is posing as Kyoshi, meets them and tells them the best way is through the vents above them. The group crawls through the vents and reaches the throneroom, but a piece of debris from the battle hits them and Tomomi falls in the middle of the fight, awkwardly pausing the ordeal. She awkwardly confirms to her group that she has the ring before crawling away, leading the Crystal Guard to think the strangers are bandits who have stolen Don's real ring. They manage to defeat the Crystal Guard, and the group recounts their experiences briefly.
Suddenly, the Omashu Queen appears from behind the throne, followed by the Don. She is surprised to see her Crystal Guard passed out, and believes the group is responsible as assassins. The Don, meanwhile, is surprised to see his wife involved. The Earth Queen begins to question "Kyoshi," who begins to cover the situation.
All of a sudden, Niya and Qi-Rah drop from the sky dome. Niya holds the Earth Queen down with Bloodbending while Qi-Rah holds the Don with a lightning blade to the throat. They tell the Don to surrender his ring, or both the Queen and his wife will die. Suddenly, Lily ensnares the Donya with vines, revealing herself to be a Swampbender working with the Celestials. Qi-Rah calls her by her full code-name "Cobra Lily," and demands her to tell them of her findings. Cobra Lily alerts her team that the ring Tomomi has is fake and that the "Avatar" is a ruse as well.
The Don refuses The Celestials' request, and Niya uses Bloodbending to slash the Omashu Queen's throat in front of the group, horrifying the strangers, especially Satomi, who is shocked to see her ex-lover on the side of The Celestials.
