Aang looked at Sokka and Toph. Katara had been unconscious for two days and they had been unable to wake her up. They were beginning to worry because she hadn't had any food or drink in all that time, and she might die of starvation. They had all been trying to figure out what had caused her to go into her coma.
Suddenly, Aang remembered what had happened right before they had left Ba Sing Se.
Aang was packing their bags onto Appa's new saddle when Katara walked up. She had walked off in a daze about ten minutes ago, and now she looked even more confused.
"Katara, is something wrong?" Aang asked, concerned.
Katara looked back at him, recomposing herself. "Nothings wrong Aang, I just went back to talk to the women who sold us the fruit. She was a very kind old woman who claimed she could see in the future."
"What did she say?" asked Aang interestedly.
"Oh, mostly just saying that I was going to be leaving the city to a perilous journey and will fight many foes. Mostly things I already know" she joked to him.
"Yeah, it seems that fortunetellers can sometime only predict the obvious."
Katara then got a confused look on her face. "Strange though, she kept insisting that I eat more of her fruit, and each time I ate it, it was sweeter and sweeter and she kept asking me if I felt tired. I feel perfectly fine. It must have been nothing. Oh well"
As she started walking away, Aang tried getting her attention, but she was already gone.
Aang was shocked. How could have not realized this before. Here, the love of his life was dying, and he had not been able to remember this vital piece of information for her survival. He felt like and idiot, and an awful friend, but knew he couldn't dwell on it. He turned to Toph and Sokka.
"Guys, I think I know how we can help Katara." And he explained it to them.
"Why didn't you tell us this before Aang, Katara might have died." Exclaimed Toph. Aang noticed that she called him by his name and that she seemed very concerned for Katara. This surprised him, as Toph usually seemed annoyed by Katara.
"YOU COULD HAVE HELPED SAVE MY LITTLE SISTER AND YOU DIDN'T? WHAT KIND OF FRIEND ARE YOU?" Sokka screamed at him. Aang could understand his frustration.
"I know I made a mistake. And I feel really bad, but right now, we just need to focus on helping her."
Sokka agreed and they headed back to Ba Sing Se to talk to that woman. They had been flying for two days, and it would take at least one to get back to the city if they went fast. Aang knew the human could only go three days with no food or water. For now it was merely a race against time.
