Korra (Janet Varney) thought she was ready to take on Kuvira (Zelda Williams) in “The Legend of Korra,” but episode 6 of Book 4 proved that the avatar still had some healing to do. Perhaps what Korra needed was a long-overdue trip back home? Well, that's just what she got in episode 7, “Reunion,” which was released Friday on Nick.com.

Check out three reveals from Season 4, episode 7:

1. Homecoming

Korra arrived home in Republic City with Opal (Alyson Stoner), Ikki (Darcy Rose Byrnes) and Meelo (Logan Wells), and reunited with Mako (David Faustino) and Asami (Seychelle Gabriel). Unfortunately, the group was joined by the always annoying Prince Wu (Sunil Malhotra). After some initial awkwardness when Mako found out Korra had written only to Asami during her three years away, things got interesting when Wu was kidnapped. Korra was able to use the spirit vines to make a connection to Wu (thanks, Toph!) and track the prince down to a train. After a daring escape, including a train-top battle with some Kuvira supporters, the group rescued Wu. The old team appeared to be back in action!

2. Captured Again

Varrick (John Michael Higgins) and Bolin (P.J. Byrne) were alone in the woods after escaping the exploding train in episode 6. However, the two were taken prisoner again when they got caught in a rope trap set by a few escaped Kuvira prisoners. After confessing that they, too, had turned against Kuvira, Varrick and Bolin made a deal to help sneak the escaped prisoners through a Kuvira checkpoint to avoid capture. Things got hairy when a guard recognized Bolin, but after a fight at the gate, the group got through safely. Bolin later apologized for how Kuvira had treated the Earth Kingdom people, and he and Varrick were offered a boat ride up north.

3. The Banyan Grove

The biggest shock of the episode came at the end with the revelation that Kuvira had found a better, stronger source for spirit vine for her weapons experiments – the Banyan Grove tree! She planned to harvest it all.
