Last week's episode entitled "Korra Alone" brings a familiar face from "Avatar: The Last Airbender," which made fans hold on to their seats for the upcoming epic, "The Legend of Korra" episode 3.

Based on reports, Toph will play a major role in helping Korra gain back her confidence after being physically and emotionally damaged during her epic fight with Zaheer.

Toph was last seen in 2008 in one of Korra's vivid visions.

Meanwhile, the upcoming episode will center on Prince Wu and the scheduled lavish celebration for his coronation as the Earth King.

Fans will see how Prince Wu boasts about his ideal additions to the extravagant celebration of his coronation, including what he describes as a "dynamic six hour show" that will feature his lineage. However, the very honest Mako asks the prince about his plans for the kingdom, and tells him that he should focus on "ruling a huge, fragmented nation." But Prince Wu insists that he knows how he will lessen his work load as the Earth King by hiring a lot of seasoned advisers to help him in all his responsibilities.

According to the spoiler posted on Recently Heard.com, the third episode of "The Legend of Korra" book 4 will return to Republic City. It will also help viewers know more about the entire members of Team Avatar after Korra went away to find peace and balance, which was missing in her life after her near fatal battle.

There are also reports that mention Prince Wu's installation as Earth Kingdom's ruler may not go as planned, considering the present state of the kingdom.

"The Legend of Korra" book 4 episode 3 entitled "The Coronation" will start streaming on Friday, Oct. 17, on Nickelodeon's online channel, Nick.com. Other ways to catch the episode include downloading the Nick app for iOS and Android powered devices. The episode can also be purchased from iTunes, Google Play, Xbox Video, as well as Amazon Instant Video.
