On Friday, "Legend of Korra" returned with its eighth episode of Season 4. It is titled "Remembrances" and showed Korra trying to save the Ancient Tree and tons more things.

In the last episode, Korra was reunited with Mako and Asami as she returned to the Republic City. However, it wasn't an easy return for Korra. She actually had to use her powers to fight Kuvira.

According to IBT, Kuvira, who is suffering from the effects of the return of Aang, planned to kidnap next Earth King Prince Wu. Kuvira's plan failed thanks to Korra, Mako and Asami. Of course, Kuvira didn't like what the trio did and now, she wants to defeat the Avatar and her friends.

What does she do? To achieve her goal of defeating Korra, Mako and Asami, she is now harvesting powers from the spirit vine, which is the strongest source of power. Kuvari wants to get the Banyan Grove Tree and experience on it for her spirit bomb project.

Toph will not be happy about this and so does Avatar Aang. Korra will have to do what it takes to save the Ancient Tree from being cut down and falling to the wrong hands. How will Korra save the day?

Also in the episode, Varrick and Bolin will team up to rescue some prisoners in one of the prison camps in Great Uniters. The episode is titled "Remembrances" because there will be some flashbacks in the episode, reported Hypable.
