The Gang's kids are about 12 years old in this story. It is not related to Crossing Paths Again, although one of the characters from it is mentioned in this story. Also, most of the kids can bend at least 2 elements, so don't get surprised in later chapters.
A girl was outside playing with a ball. She had short brown hair. She wore an orange dress with a light blue ribbon in the middle tied at the back. She ran over to a wooden bridge.
"Caitlin, come inside, sweetie!" A woman in a blue Water Tribe outfit called.
"I'm coming, Mom!" Caitlin called back. "Look at what I just did." The woman came over and saw her daughter had made a tiny water orb by using waterbending.
A man in an orange robe came out. "Katara, what's going on out here?"
"Our daughter learned how to waterbend." The woman told him. "She is just like you, Aang."
"Yeah, though she's better at using the air scooter than I was when I was her age." He pointed out.
"You should get inside before it gets dark out." Katara told Caitlin. "The sun's starting to set."
"Okay." Caitlin agreed. She ran back to the house, which was not too far from the bridge.
"I have to go somewhere early tomorrow morning, but I promise I'll be back in the afternoon." Katara said.
"Do you have to go, Mommy?" Caitlin asked.
"An old friend of mine needs help, sweetheart." Katara told her. "I've finally learned how to heal to the point where I can get rid of injuries, scars, even blindness. But you're father will be staying home with you."
"Well, I guess we could spend a little time together." Caitlin said. That night, Aang came into her room.
"I know it's tough for you, Caitlin." He told her. "It's not easy being the Avatar's kid."
"Yeah, but you met so many amazing people!" Caitlin pointed out. "In fact, Sierra's my best friend."
"Isn't she you're cousin?" Aang pointed out. "Remember, she's the daughter of you're mom's brother, Sokka."
"True."
"When I was you're age, I was friends with a boy who is now the Firelord."
"You know Zuko?" Caitlin asked. She was getting excited.
"Yes, and I understand that he has a little girl about you're age." Aang told her. "You're mom and I were going to visit him in a few days and we were going to invite you to come with us."
"This is so cool! I actually get to meet a real princess!" Caitlin shouted.
"Try to stay calm." Aang told her. "In the meantime, we can go into town tomorrow while you're mom's away."
The next morning, Katara headed over to an old friend's house. She was living close by. Before she could knock, a voice said, "Come in. I've been expecting you."
There was a woman in a green robe sitting in a chair. She looked like she was sleeping.
"Are you Lady Katara?" A girl asked.
"Yes, I am."
"Can you help my mom see again?"
"You're mom?"
"Well, stepmom, actually. I started living with her a couple years ago when my real mom passed."
"I know how you feel." Katara said. "Anyway, I'll do my best." She turned to the sleeping woman. "Toph, try to open you're eyes. I can help you see more clearly."
"Thanks." Katara used her healing powers. When Toph opened her eyes again, they were fully colored green.
"It's amazing. I can see!" Toph got out of her seat. "Thank you, Katara." She shook her hand. "I see you've met my daughter, Tina."
"I have a daughter too. Her name's Caitlin."
"She's the Avatar's daughter." Tina stated.
"I know. But she's still a normal girl like you, Tina." Katara said. "Anyway, I got to go. I'm expected to make a trip to visit an old friend."
