Prince Zuko is using his fire bending to heat up the rice pot

Katara comes over and starts kissing Zuko on the lips as Zuko kisses Katara lips back and then they hold each other in their arms as now the rice pot is getting hot and boiling

Sokka: what is taking Zuko so long to make tea?

Aang: yeah? Maybe I should go check on him

Toph (blind): I'd stay away from the rice pot as much as possible
