The Legend of Korra season 4, episode 4 streams today on Nickelodeon! Here’s everything you need to know about “The Calling.”

The air kids will head out on a mission to find the missing Avatar when The Legend of Korra season 4, episode 4 streams today on Nick.com. The episode, titled “The Calling,” will focus on Jinora, Ikki, and Meelo (and their trusty bison Pepper) as they try and find Korra.

A sneak peek from “The Calling” shows the three siblings setting off on their journey – much of which hinges on Jinora’s ability to sense Korra’s spiritual energy.

But thanks to her trauma and remnants of the Red Lotus’s poison still in her blood, Korra’s spiritual energy seems to be at an all-time low. Finding the Avatar may not be the simple matter the kids and Tenzin think it will be; and if the clip is any indication, neither will peaceful travels between the three spirited air kids.

While his children are off searching for Korra, Tenzin will attempt to find a diplomatic solution to Kuvira’s semi-hostile (and not at all surprising) takeover of the Earth Kingdom Empire.

And whether or not Jinora, Ikki, and Meelo manage to find Korra, we certainly hope that she’ll show up in the episode. Perhaps that crazy swamp has more secrets to share with the struggling Avatar.
