The sun was beating heavily on the island that day. Lin wiped the sweat off of her forehead. She let her head hang back on the chair and look straight at Kya.

"Can you get me?"

The eleven year old bent water out of the nearby fountain and allowed the water to drench Lin. "There you go."

"Thanks."

Bumi was lying out on the ground sweating profusely. "Tenzin, how can you stand wearing those air nomad clothes? It has to be at least a hundred degrees out here!"

"I'm an airbender. I can fan myself off when ever I want." The youngest of the avatar's children scowled at his older brother

Kya just scoffed. "Woohoo, lucky you."

Lin rolled her eyes at the three siblings. The eldest Bei Fong sister decided that staying at home while Toph was at work was boring. Now that they were both older, Lin and Suyin made constant trips to Air Temple Island to escape keeping each other company. Whenever they stayed home, Toph would find them destroying the backyard earthbending or yelling at each other. It was saner on most days when the girls were with the avatar's children, even if the three fought as well.

Thirteen year old Bumi stood up and started to prance around. "Look at me, I'm Tenzin. I don't worry about the heat because I'm an all mighty airbender. The only one born in a hundred something years. Weeeeee!"

Tenzin blasted his brother with air causing him to fall over. Bumi got up at once and started wrestling his younger brother on the floor.

It took Kya to splash water on them to get them to stop. Lin rolled her eyes once more.

"What is your dad gonna say when he finds out you two were fighting? Especially you Tenzin?" Eight year old Lin smirked to herself.

The young airbender walked over to Lin and sat next to her. He closed his eyes and began meditating. Lin expected as much. Bumi was about to comment once again, but Kya beat him to it and hit the back of his head.

"Okay then." Lin began. "It's obvious that we are all frustrated and bored. Let's do something."

"Like?" Bumi asked.

"I don't know. I suggested we do something. It's your guys' job to come up with such something."

Kya spoke up this time. "How about, let's play 'Where's Suyin?'"

The eldest Bei Fong perked up in concern. "What? What kind of game is that?"

Bumi chuckled. "Haven't you noticed? Suyin hasn't come back from the bathroom in like two hours."

"How did we not notice?" There was panic in Lin's voice. "We have to go out and find her!"

"Wow, Lin. I've never seen you so concerned for your sister."

She shot Bumi a glare. "If I don't find Su, then Mom is going to bury me in the backyard."

"We'll find her, Lin." Kya assured her.

The four children began searching the island. She wasn't inside the house and the kids had to try hard and not heighten the suspicions of Katara. She wasn't in the air acolytes dormitories. The training grounds were barren of any signs that Su had passed through. The group rimmed the beaches and was yet again unlucky. They checked every tree, bush, and rock that was on the island. Lin had even used her seismic sense to check for Suyin's whereabouts. She was surprised to find nothing at all.

They arrived back at the training grounds when Lin screamed in frustration. "Where is that brat!?"

"She must have used the bathroom somewhere else." Bumi laughed.

Kya's eyes widened. "You don't think she went off the island do you?"

The avatar's children cringed as Lin bent the floor out of shape. The eldest Bei Fong threw rocks in every direction. "Oh, that is exactly what she did. This is the kind of thing that she likes doing. Making things harder for everyone. Ughhhhhhhhhh."

"Maybe you should calm down." Tenzin shakily suggested.

Lin whipped her head around. "I will when we find her!"

"And where do you think you are going?" Kya yelled back. "You really think we can just leave the island?"

"I can." Lin said as she continued walking.

"You think you are going to find her just like that? Republic city is huge!"

Bumi's words stopped Lin in her path. As much as an idiot that everyone thinks he is, Bumi was right. Lin was only eight. She didn't know her way around the city yet. The thought only made her concern heighten as Suyin was only six. If she was lost, Lin didn't know what she would do or what Toph would do.

"What am I supposed to do then?" Lin easily fixed the ground to its original design.

"Tell Mom." Tenzin suggested.

Lin growled once more. "That brat is going to get me in so much trouble."

"Mom could probably find her faster."

"You're right."

The group headed towards the house. Lin readied herself to tell her Aunt about Suyin's whereabouts, prepared that she would not be happy. They found the waterbender reading in the living room.

Lin rubbed the back of her neck and approached her. "Um, Aunt Katara?"

The aged healer put down her book and looked at Lin. "What is it? Is there something wrong?"

The small girl sighed. "Yeah. Suyin is missing."

"What are you talking about?" Katara sounded genuinely confused.

"Well," Lin took a deep breath. "She said she was going to bathroom about two hours ago and hasn't come back yet. We looked all over the island and couldn't find her anywhere. Our best guess is, she left the island."

"Are you sure about that?"

"We looked everywhere!"

Katara furrowed an eyebrow. "Then who is that eating at the kitchen counter?"

Lin, Kya, Bumi, and Tenzin all looked towards the kitchen and found a small girl seated eating baby carrots. Suyin was swinging her legs from the tall chair that she was currently sitting on. The smile on her face indicated she was enjoying her snack quite nicely.

"SUYIN!"

The youngest Bei Fong turned around and smiled. "Hi, Lin!"

Lin approached her sister with wide eyes. Naturally, she looked her sister up and down for any injuries or signs that she had been assaulted. She wouldn't admit it, but she was pretty relieved to find her sister unscathed. Now, Lin could just be mad at her.

"Where the hell were you?"

Katara scolded her immediately. "Hey! Watch your language!"

Lin seemed to just let the disciplinary action slide. "We have been looking for you for two hours!"

Suyin raised an eyebrow at her sister. "I told you, I went to the bathroom."

"Where? In Ba Sing Se!?"

"No!" Su was starting to get annoyed.

Lin growled. "Where were you? You know Mom doesn't like it when we aren't traveling together. You could have gotten hurt!"

"I was fine!"

Katara walked over to the argument. "Is this true, Su? Did you get off the island?"

Suyin didn't answer. She played with her carrots with her head turned down to avoid Katara's eyes.

"Well?"

Su's answer was mumbled under her breath. "Maybe."

The waterbender shook her head. "Your mother is hearing about this."

The young girl hopped off the chair and began running out of the house. This only angered Lin further.

"You aren't leaving again, Su!"

Lin found her sister standing in the middle of the training grounds. She was scowling at her as if it would burn right through her body.

Suyin yelled at a high volume, enough for the birds to fly away from the surrounding trees. "Why can't you ever let me have fun?"

Lin laughed at her sister's immaturity. "Fun? Republic city isn't exactly a playground."

The smallest Bei Fong clenched her fists. "You wouldn't know. You don't know how to have fun!"

"Shut up, Su! You don't know anything." Lin screamed back. Tenzin, Kya, and Bumi were now outside watching on the steps.

Suyin had enough. Quickly, she sent a fair-sized boulder towards her sister. Lin jumped out of the way quickly and matched her sister with fast moving rocks. Several were dodged by Suyin, but there were a few that scratched her up. Suyin breathed hard and fought on.

The small girl sent sheets of earth towards her sister in hopes of pushing her down. Lin had a harder time dodging these. The action took enough energy to delay her reflexes and get hit by a rock. Lin felt the wind knocked right out of her.

Thinking she had won Suyin smirked and crossed her arms. Seeing her older sister lying on the ground was slightly rewarding at the moment. Once several seconds past and Lin still had not gotten up, however, Su's eyes switched from victory to worry.

"Lin?"

The moment the name left her mouth, the earth cracked open beneath her and Suyin fell into the crack. She was stuck immediately.

"Mom! Suyin is stuck in the ground!" Bumi yelled as he ran back inside.

Suyin's breathing could be heard across the training ground. Hot tears of frustration were starting to collect in the six-year old's eyes. "Cheater!"

"Not cheating!" Lin yelled back. She held her stomach in slight pain.

"Stop thinking you can tell me what to do!"

Lin scoffed. "I'm not thinking anything. I'm just following what Mom said!"

Suyin continued to challenge her sister. "That's why you are so boring!"

"I'd rather be boring than stupid like you!"

The feeling of cold water hitting both Bei Fong girls halted their conflict immediately. They looked over to Kya and found her mother standing, hands on her hips, ready to yell at them like they had never experienced before.

Katara's voice boomed. "Will you two just stop? Both of you are acting disrespectfully."

"She started it!" The Bei Fong sisters said together.

"It doesn't matter anymore!" The waterbender's fury scared her own children that stood beside her. They knew exactly how angry Katara could get. "Lin, get your sister out of there. I just got off the phone with your mother."

Both girls swallowed hard.

"She is leaving the station early."

Lin and Suyin looked at each other.

Mom never gets off work early.

Reviews are like presents on Christmas. They mean a lot to me!
