Author's note: Hey guys! So as the Legend of Korra book 3 progresses and we learn more about Lin and her family, if things in my story don't go as canon, I hope you guys don't mind too much. I already went back and corrected Suyin's name. But yeah, I just wanted to let you guys know that some things might not make sense. That's why they call it fan fiction right? Haha. Anyways, Enjoy!

It had been several weeks since Toph had her conversation with the girls. So far, it seemed that her talk worked considering that arriving at Air Temple Island at the end of the day to get Lin and Su did not include pulling the two off of each other. Toph was more surprised to find Lin helping Su put on her coat and gathering all her toys. Suyin would voluntarily hold hands with her sister when boarding the boat, knowing that Lin hated sea travel like her mother. Toph did not say a word in fear of ruining such bliss.

The Bei Fong girls were finally acting like sisters.

The act, unfortunately, was cut short when Suyin earthbended for the first time.

It was on a regular Saturday that Toph remembered her girls fighting once more. On the weekends, she had devoted her time to giving all of her attention to her daughters, which included training Lin in earthbending. The eldest Bei Fong sister had first shown her bending abilities at the age of four by hurling a rock at her mother during a tantrum. Ever since, Lin had been excelling beautifully. This was also an exciting time as Suyin was now four years old. Toph could sense that Su's time to start bending was coming soon.

"Ready?"

Lin took her stance. "Let's go!"

Toph stomped the ground and lifted a medium size boulder into the air. She glanced towards her blind folded daughter, making sure she wasn't cheating. Everything checked, Toph let the boulder fly towards the six-year-old.

At once, Lin bent a rock wall up in front of her to take the blast from the boulder. She found her body shifting a bit from the force, but nonetheless, she blocked her mother's attack. The small girl let out a shaky breath.

Toph nodded and continued. Moving around her daughter, the earthbender sent boulder after boulder. Lin did her best to dodge or block each attack. Often she would send her own boulder to counteract her mother's. Other times she would dodge quickly and return back to her stance. The exercise continued for another ten minutes. Shaking things up a bit, Toph sent a rock wall. Lin buried herself into the ground. The dust cleared and the six-year-old was nowhere to be seen in plain sight.

Toph put a hand on her hip and felt as her daughter moved underground. She went in a snake pattern before stopping right underneath Suyin. The smallest Bei Fong was presently building a dirt castle. The ground under Su began to rumble and at once, Su floated up into the air on her own little island. The small girl giggled in laughter with her hands up.

The chief of police chuckled slightly. "I think your sister likes the ride, Lin."

Su began to ascend higher, reaching taller than the house.

Maternal instincts kicking in, Toph crossed her arms. "Alright, Lin, I think that's enough. Put Su back on the ground."

Toph's ears twitched at the sound of Su's giggles too distant for her liking.

"Lin." She was sterner this time. "Are you listening? Put Su down."

Lin's little head popped out of the ground and she looked confused. "I thought you were doing that, Mom."

"I'm not doing anything. Stop playing around."

"Mom, it's not me." Lin looked up to find her sister five stories up. "It's…Su."

Toph's eyes widened. She quickly scanned the area to make sure that no one else was around the area to be causing Su's levitation. Relieved that the three of them only inhabited the training area, Toph whipped her head towards Lin.

"Where's Su?"

Lin had completely come out of the dirt now. She held the green blindfold in her left hand and was staring straight up. "She is on a piece of earth right above the house."

"What?" Toph glanced up in a general direction. "Get her down!"

Lin cried out. "Su! She's falling!"

At that moment Suyin slipped off her small dirt island and began her descent towards the ground of the training area. She screamed loudly while waving her arms in every which way. "Mama!"

"Su!"

Toph ran in the direction of her daughter's scream. However, Lin had already started moving and was bending her way up towards her sister. Pillar after pillar erupted and Lin jumped on to each. Higher and higher she climbed until she finally jumped into the air and caught Su mid air.

"Mom, sand!"

Toph bent the ground into sand just as Lin hit the ground. The eldest Bei Fong rolled a couple of yards, her sister safely wrapped by her body. They came to a halt in front of the porch.

Lin let go of Su who was now wailing loudly. Toph was there at an instant pulling Suyin into her arms. Her cries quieted quickly thanks to the comfort of her mother's contact.

"Are you alright, Lin?"

The older Bei Fong sister answered breathlessly. "I'm fine."

Toph crawled over to her and helped Lin sit up. "Nothing serious? Nothing broken? Or hurting?"

Lin grunted slightly in discomfort. "Just bruises later."

"We can fix those up later. I'm just glad both of you are okay." Toph pushed Lin's hair back, her hand wiping the sweat into her daughter's hair. "Thank you, Lin."

Lin smirked at her mother. "No problem, Mom."

"No really, thanks. You know how I hate stuff like that. Always feel like I can't do anything."

"I know." Lin giggled a little.

Toph put Su back down and directed her towards her sister. "Don't you have something to say to Lin?"

Su scowled at her sister and turned back to her mother. "Mama, up!"

"Hey, your sister just saved your life. Don't you think you should thank her?"

Suyin began stomping on the ground. "Lin hurt Su. Mama, up!"

Toph gave in and picked up her youngest. "What are you talking about, Su?"

Suyin raised her right arm and presented her bloody elbow to her mother. Toph felt the blood instantly.

"Come on, Su. Lin didn't mean it. You could have ended up worse."

Suyin continued to scowl at her older sister. She waved her arm and the earth rumbled slightly under Lin's feet causing her to topple over on to her behind. The eldest Bei Fong glared at her sister.

"Hey!"

Toph tried keeping Su's hands down. "What do you think you're doing? Lin just saved you from falling to your death. That shouldn't be how you repay her."

"Lin hurt!" Su flailed her arms harder causing various pebbles and rocks to fly towards Lin.

Lin bent all the rocks away. "Stop it, Su! Now you're hurting me!"

Toph pushed Su's hands down to stop her from bending. "Suyin, what the spirits has gotten into you?"

However, the smaller of the children started to cry in frustration. Toph sighed also irritated, not at all used to the children fighting again.

On the ground, Lin began walking towards her sister angry only to find her mother's hand stopping her.

"Fighting her won't do anything."

"But," Lin pulled on her mother's arm. "She was hurting me! You said we shouldn't fight each other!"

Toph growled slightly "I know, I know. But Su is still small. She doesn't understand it yet. She didn't mean to."

"But-"

"Leave it be, Lin."

And with that, Toph walked back into the house, Su on her hip and still crying. Lin was left in the training grounds. Her clothes were dirty and her arms and legs were probably going to be sore later due to the various bruises that will soon appear. Lin stared into her home and watched her mother start cleaning Su's wound the best she could. Toph wiped Su's tears away and talked to her gently.

Lin just glared.
