I've never seen this episode before but from what I've heard, in The Chase, Aang and the gang team up with Zuko and Iroh to fight Azula. My questions are: Why were they helping each other? Did Zuko want to capture Aang? How did Zuko feel when he saw Aang? If they all teamed up to fight Azula then why didn't Zuko and Iroh join Aang's group.

Like I said. I have never seen this episode in my life, so if somebody could answer my questions, that would be great.

When Zuko finally catches up to Aang and Azula, they begin to have a three-way battle. (Of course, it seems that Zuko is concentrating all his attacks on Azula and doesn't seem to care much about catching Aang. Same with Aang, he doesn't seem to worry about Zuko). Zuko uses red fire blasts while Azula uses blue fire blasts, and Aang uses his standard airbending. Soon Katara and Sokka join in to aid Aang. Then, Iroh joins to aid Zuko. Finally Toph joins in, asserting her place back with her friends. Azula, realizing she is outnumbered, pretends to surrender, only to slyly blast Iroh in the chest. This causes everyone to attack at once; however, Azula creates a fire shield and vanishes.

Aang notices Zuko, kneeling over a wounded Iroh. The group approaches them, but Zuko tells them to get away. Toph looks upset; her feet are zoomed in on a groaning Iroh, perhaps implying that she recognizes him from earlier and also possibly that she recognizes his wounded condition. Katara tries to reason that she can help, but Zuko will not hear it. He shoots some fire over their heads, yelling at them to leave. Unable to do anything else, the group decides to leave.

That night, Appa lands on a rock formation, and Toph can be seen sleeping next to Katara and the others
