Gentle

He hadn't seen his wife all day and it was starting to worry him. Katara said that she was going out for a little while this morning and would be back around lunch. Lunch came and went with him making lunch for Bumi, himself and Katara. He waited and waited and still no Katara at all. He wrapped up her lunch and slid it into an icebox to keep it cold for her, for later.

"I really wonder where Katara could be" Aang had wondered to himself one of the many times that day, "she usually never misses lunch"

Aang played with Bumi for a couple hours and during a game of tag, looked up at the sky to see the sun was not setting but not at noon anymore. He figured it was around two o'clock which he then decided to have Bumi take his afternoon nap. Both parents knew that Bumi was a bit of a wild child and had a lot of Aang's personality but they loved him no matter what.

Surprisingly it was easy for Aang to get Bumi down for his nap today as Aang had tired his son out from playing tag. He tucked Bumi in and gave him a kiss on the cheek as his son put his head on the pillow, closing his eyes to answer the call of sleep.

Aang shut the door behind him and head out to look for his beloved. A million thoughts were running through Aang's mind as to where Katara could be.

"She usually doesn't stay out this late at all and if I know my wife….." his voice and thoughts trailed off into different scenarios that could have happened. He came upon one of the old temple doors which he knew to Airbend to unlock, he did.

He peeked his head inside and called out, "Katara!? Katara are you in here?" he was met with dead silence. He pulled his head back and airbent the door shut.

"She isn't is that room, let me try another room" he said quietly

He turned and walked down one of the Air Temple hallways. Aang took a left and then another left. He faced another Air bending door and airbent it open. He was again faced with complete darkness. Aang peaked his head in again and called out, "Katara, Katara are you here" again he was met with dead silence.

He shut the door and really started to worry more.

"At this point she would be grand champion of Hide-Aang-Seek" he muttered to himself with a slight chuckle, "Let me check a couple more rooms before getting Appa"

He went about to a couple of other rooms and faced the same blackness. Aang was more than worried at this point and was starting to get a little mad at Katara.

"Why couldn't she tell me where she was going?" he thought to himself, "What if something bad happened to her!" his mind was now starting to panic and he saw that the sun was setting more and more.

"Pretty soon I'll have to wake Bumi up from his nap" Aang said quietly. The thoughts about getting Appa out to look for Katara had dissipated when he remembered there were two more rooms to check.

He came upon the music room, he airbent the door and peaked in. there wasn't blackness but a dim light that shone through a sliver of a window. He could see that there wasn't anybody in the room especially his wife.

He shut the door and turned around quickly at the sound of a faint whistle coming from the room behind him. He saw that the door wasn't an Airbending door but a regular one. He turned the knob slowly and pulled the door out. Aang was greeted to a great surprise. The room had a long corridor and in the middle of the corridor was Katara sitting in the lotus position with an Airbender's flute. Her back was turned to Aang which Aang was grateful for as he didn't want to startle her. He slowly crept into the room and grabbed another Airbender Flute from the ground with the gentlest of ease, making sure to not make the slightest sound.

He watched as Katara was practicing intensely, her brows were furred and her face swollen from frustration and the remnants of her crying.

She kept trying to play a little melody that Aang picked up on right away and it shocked him to say the least.

"She's trying to learn Flight of the Sky Bison" Aang thought to himself, shaken from the sight he saw and melody he heard, "But why would she want to learn the song when everytime she heard me play it, we both cry"

After a couple more mins of watching Katara struggle to play the song, Aang had enough.

He stepped out from the shadows and put a gentle hand on Katara's shoulder. She jumped from the touch and rushed around to meet the loving and crying smile of her husband.

"Aang!" Katara's voice was shrill from surprise, "What are you doing here?"

"I have been worried about you all day sweetie" Aang choked out as another tear slid down his cheek, "I wanted to see where you were"

Her cheeks flushed a raspberry color and she hung her head down as if in shame.

"I have been here trying to learn this song for you" Katara sheepishly admitted to her still bewildered husband.

Aang's bewilderment wasn't going away anytime soon but he was quick to ask, "Why did you want to learn the song?"

Katara let out a chuckle, "sweetie, we may cry every time we hear the song but that doesn't mean I dislike the song, it's quite the opposite, I love the song"

Aang's lips curled into his goofy grin as tears kept falling from his face. Katara had noticed the tears and was puzzled by them.

"Aang, are you okay? Why are you crying?" Katara had confusion in voice

"These aren't sad tears sweetie, these are tears of happiness" Aang sat down in front of his wife and wrapped her in the tightest hug he ever gave her, "Nobody has ever done this for me before and I want to learn any songs from the Southern Water Tribe" Aang whispered into her ear.

They stayed like that for what seemed to be eternity until Aang opened his eyes wide, "I forgot about that Bumi was taking his afternoon nap"

Katara giggled softly, "You want me to go get him" she said.

Aang broke the hug, "it's okay sweetie, I'll go get him and come right back"

"Okay" Katara smiled, "I'll be right here"

Aang quickly got up and Airbent an Air Scooter which zipped outside the room all the way down to Bumi's room.

Ten Minutes goes by and Aang comes back with a still sleeping Bumi and Katara's wrapped up lunch.

Katara smiles at her sleeping son, "How was he today?"

"He was great" Aang said with his own smile, "We ate lunch and played tag, which he is great at by the way and then I put him down for a nap with ease and he's been asleep since"

"Sweetie that's great!" Katara was overjoyed at hearing the day went smoothly with their son.

Aang gently put Bumi down on one of chairs in the library room and turned to pick up the Airbender Flute.

"I know you wanted to surprise me by learning the song and I can see you are getting frustrated, let me help you learn it and we can play it together" Aang had his crooked goofy grin on his face saying this to his beloved.

"I would love that" Katara's sheepish smile came back, "This song is harder than I sounds"

Aang laughs and agrees, "its not one of the easiest songs to learn but I'll teach you the song"

They stayed up all night practicing, Aang patiently going over section by section with Katara. He helped her every time she messed up or would start to get frustrated. She eventually learned the song and now every time they get a chance, they play it together and start to cry.
