The End of the Avatar
Once Zaheer had Korra in his hands and had unlocked weightlessness, he took flight to a mountainside hideout where the new Air Nomads were held, guarded by the Red Lotus sentries.

After Korra was chained, Zaheer ordered for the posion, describing its effects, while the Red Lotus sentries watched and waited for the order to administer the poison. On Zaheer's command, the sentries bent the metallic liquid into Korra's skin, watching as Korra entered the Avatar State unwillingly.

Meanwhile, two other Red Lotus sentries who were guarding the Air Nomads were asked by Pema to provide water for her children. The sentry agreed, but was airbent by Jinora, who thereby stole his keys. Opal began opening the locks, and the two sentries standing by were incapacitated by Lin, who earthbent one of them to unconsciousness, and Asami, who electrified the other.
