When Katara and Sokka meet with an old friend (Bato of the Water Tribe) it reanimates old friendships, and sparks many memories. Unfortunately, Aang, who never knew Bato, feels slightly left out, and begins worrying if Katara and Sokka will ever leave him. When an urgent message from Katara and Sokka's father arrives, Aang, fearing for his friendships, hides it. It's not that simple, though- sparking up his conscience, Aang begins to feel guilty. This problem is complicated even further when June, Prince Zuko's new bounty hunter, comes to capture Aang, but finds Karata and Sokka instead.
