Later that evening:

Katara's POV:

I'm lying in bed staring at the ceiling so stuck in thought that it starts to become suffocating. I push the duvet back and swing my legs over the edge of the mattress.

"Katara?" Yun asks sleepily from his bed on the other side of the room. I turn apologetically.

"I'm sorry, I didn't mean to wake you. Go back to sleep." I hush, but he does the opposite and pushes himself up to gaze at me in concern.

"Is something wrong? You were quiet at dinner too." Yun notes with furrowed eyebrows. I bite the inside of my cheek as I turn away from him.

"Do you think...he should know that he has a son?" I ask suddenly. The 'he' in question is obvious. Silence penetrates the air for several moments before he finally replies.

"What brought this on?" The doctor queries as he pushes himself off his bed to cross the distance between us. I feel my bed sink beneath me as he takes a seat beside me. I sigh and stare at the carpet.

"We bumped into each other today. He recognised me from when I talked to him on the first day he lost his memories and wanted to know more about his past. I shut him down of course, but..." I trail off with a helpless shrug. The man beside me hums in understanding.

"I see. You're doubting whether you should keep Yatsu a secret?" Yun clarifies. I flinch.

"I wasn't until I met up with Toph who thinks it's a great idea." I mutter before twisting my body to look at him. "What do you think?" I ask anxiously. My fiancé sucks his bottom lip in thought.

"If I was talking from a moral point of view, then telling him would be the right thing to do. I know if I was in his position I'd want to know, memories or not. The selfish part of me however, can't help but worry it will ruin what we have now though." The man admits with a sheepish smile. My lips twitch upwards in agreement.

"That's what I was thinking. I don't think I'm ready for him to know. Not sure if I ever will be, if I'm honest." I confess, but Yun tilts his head forward in thought.

"But what will you do when Yatsu inevitably asks for his Dad? And that will happen. He might be too young right now to ask about it, but one day he'll demand to know more about his real father and if you don't tell him I have no doubt his genius little mind will work out a way to find him." Yun points out and I find myself deflating.

"But that's still years away, I can at least delay it till then. Who knows, maybe he won't be as curious as we think he'll be, especially if he already has you as a dad." I comment hopefully, but the man's face crinkles with sadness.

"We both know I won't be able to replace his actual Dad." The consultant utters quietly. I cast my eyes away from him, hating that everyone is saying the exact same thing. I flop backwards on the mattress in frustration.

"You still didn't tell me if I should tell him about Yatsu or not." I mumble as the earthbender peers over me. He grins slightly at my annoyed expression.

"That's for you to decide. You're the one who's been raising Yatsu all these years. Do you want him to know?" Yun asks in curiosity as he lays down beside me. I bite my lip at the question and look away.

"Would it be bad if I said no?" I whisper so quietly that the man has to strain to hear me. A small hum escapes him.

"As I said, you've been the one raising him, it's your choice. Although, it does beg the question of why." My fiancé queries. I chew my lip and roll over to my side to face him.

"I'm scared if he comes back in my life that it will be hard to let go of him again." I confess. It's silent for a long time after that. After an age, he rolls over to his side so that's we're face to face as he gages my expression.

"So, you still have feelings for him?" Yun questions casually and I wince at hearing it said so boldly. I close my eyes and roll over to my back.

"No. But I wouldn't be surprised if I fell for him again." I explain honestly. I feel the mattress sink beneath me and open my eyes to find Yun hovering over me.

"Then who do you have feelings for right now?" The man asks as he peers down at me with his green eyes. I quirk an eyebrow.

"Who'd you think I'd share a room with?" I tease as I hit his shoulder lightly, but he catches my hand as I start to withdraw the appendage.

"Sharing the same room is different from sharing the same bed." Yun points out with a cheeky smile. I flush and slip my hand out from his.

"I'm not ready for that step and where it would lead to yet." I say with an apologetic smile, but the doctor gazes at me with understanding.

"Trust me, I'm as anxious as you are about it." He admits with a light laugh as he bends down to capture my lips in his. "But I enjoy this." He murmurs when he pulls away. I grin and pull him down so that he's lying beside me again. I rest my head against his shoulder and breathe softly.

"Me too." I murmur back. My eyes are just about to flutter to a close when loud banging at the door startles the both of us.

"Auntie Katara!" Fuki yells from the other side of the closed door. I jerk up from the bed immediately and cross the room to open the door just as Yun pushes himself upright with furrowed eyebrows. When I open the door, I find the pre-teen staring at me anxiously. I frown and crouch slightly to meet her eyes.

"What's wrong? Did you have a nightmare?" I ask as I check her for any signs of shaking, but she seems fine which is confirmed a moment later when she shakes her head in denial.

"No, it's...Yatsu." Fuki mumbles while chewing her lip. My eyes widen in panic.

"What happened? Is he hurt?" I fire out as I clasp her shoulders. Again, she shakes her head, but her face still looks serious.

"He's... he's stuck at the top of the cupboard and can't get down." Fuki explains. My lips part in shock and I don't spare another minute as I dash out of my bedroom and straight for Yatsu's. When I barge into the room, his crying is the first thing I hear and when I whip my head towards the tall cupboard I find him he's tottering near the edge while holding at the wall desperately.

"Yatsu, mummy's here, don't worry." I reassure him gently and his crying suddenly stops as he peers down at me.

"Mummy! I don't know how to get down and I can't hold on for long." He cries back as his little hands start shaking. I bite my lip and go to stand just under him just as Yun and Fuki enter the room. Yun's eyes widen at the sight.

"How on earth did he get up there?" The earthbender wonders in disbelief. I ignore his question and open my arms.

"Yatsu you can let go; I'll catch you." I try to reassure, but he's shaking his head violently.

"No! Come and get me." He begs and I look at him in worry.

"Sweetie, none of us can reach you, you're too high up. I promise I'll catch you, just let yourself down." I voice desperately, but he's still shaking his head.

"Mummy I can't, I'm too scared." My son croaks and he starts crying again. I bite my lip and turn to Yun.

"Do you have a ladder?" I ask hopefully, but at his head shake, my heart drops.

"Shoot." I curse as I turn back to eye my crying boy. "Yatsu, maybe if you get down the same way you got up?" I suggest lightly, but the boy's lips wobble.

"I don't know how. I just flew up when I sneezed and I've been trying to sneeze again, but it's not working." The young boy explains with scared eyes. Beside me Yun and his daughter's mouths are agape, but I stiffen at his words. 'Oh no.' I think with dread.

"We could call the fire brigade; they'll be able to get him down? Or I could just earthbend the wall down?" Yun suggests as he comes to stand beside me. I shake my head.

"They'll be a while and he doesn't look like he can hold on for much longer. Plus, asking you to earthbend affects the value of the house, you know that." I shoot down his ideas while chewing my lip. I turn back to look at my son. "Yatsu, I'm going to use my bending to bring you down, ok honey?" I suggest and finally the boy gives me a tiny nod of his head.

"Ok Mama." He whispers. I chew my lip, 'a couple of water whips should do the trick, but...I don't want to leave any red marks on him. If I had enough water, I could bend myself up and grab him, but waiting to fill up the bath would take too long.' With a resigned sigh I grab some water bottles and bend two streams of water.

"Katara, I really don't mind using earthbending, I don't care if it affects the value of the house." Yun insists when he notices my hesitation, but I stubbornly shake my head.

"No it's ok, I'll get him." I reassure as I bend one stream of water around his waist. "Honey does that hurt?" I holler up to him and when he shakes his head, I release a breath I didn't know I was holding. "Ok good, I'm taking you down now." I instruct and pick him up, his body tightens, but he doesn't make a sound.

After a couple of minutes, he's back on the ground and I drop the water on the floor as I tug him tightly into my chest.

"Thank the spirits." I breathe out, relieved to feel his warm little body in my arms again and it's only then do I realise I'm shaking.

"Mummy I'm sorry for scaring you." Yatsu whispers with a hiccup. I still my shaking and go to rub his back.

"No, no. You didn't do anything wrong. I'm sorry it took me that long to get you down." I murmur gently as I pull him up from the ground and into my arms. I cast my eyes over him, checking for any injuries. I reach forward to heal the slight redness on his fingers and he giggles.

"Mama, that tickles." Yatsu laughs and my heart leaps up in my throat at seeing the smile on his face again. I lean forward to rest my forehead against his.

"Love you my little one." I murmur before pulling my head back. He grins and throws his arms around my neck.

"Love you too Mama." My son whispers, but then his face grows anxious as he fidgets in my arms. I blink, ready to set him back on the ground, but he stops when he notices my intentions. "Mummy, why..." He pauses to lean in towards me as he drops his voice to a hushed whisper for only me to hear. "...why did I fly?" Yatsu asks innocently. My arms tense up at the question and I swallow thickly.

"I... I'll tell you about it later." I stall as I pop him back on the ground. "I think I'll call the school tomorrow to tell them you'll have the day off just in case anything like this happens again." I suggest. The boy looks displeased with my answer, but he doesn't argue and nods his head. However, Fuki looks at us confused.

"Are we not going to address the fact that he sneezed and got stuck up a 2-metre cupboard?" The girl asks, sounding perplexed at us for not talking about it. Yun rests a hand on her shoulder.

"I think we all need to go to bed. You have school tomorrow and I have work." Her father utters firmly, leaving no room for argument. She pouts.

"Just saying, it seems like Yatsu is an air-" Fuki is promptly cut off by her father.

"I said that's enough!" Yun raises his voice, silencing the girl as she flinches. I clench my jaw at the glaringly obvious revelation that I've been so desperately hoping wouldn't be true. 'Fuki is right, this is something that only an...airbender could do.' Just thinking about it has me feeling nauseous.

I watch as Yun steers his sullen daughter out of the room, I shoot her a smile as she leaves, but hers is half-hearted at best and I release a silent sigh. 'Her father can be quite strict with her.' I note to myself and wait until they disappear out of the doorway. The door closes behind them with a soft click.

"Mama?" Yatsu murmurs with a tug of my nightgown. I look down at him with furrowed eyebrows.

"Yes dear?" I voice as I crouch down to meet his eyes.

"Can...can you sleep here tonight please?" The boy requests meekly. I smile at him warmly and take his hand.

"You know I was just thinking the same thing." I tease as I give his tummy a tickle before hoisting him back onto his bed. I slide in beside him and pull the duvet over us. "Are you comfy? I'm not squishing you, am I?" I double check, but if anything, the boy latches onto me.

"No Mummy." He whispers as he nuzzles his head into my chest. My heart swells with love for the boy as I rest my head on the pillow. I'm just about to close my eyes when the child speaks up.

"Mama?" Yatsu probes. I flicker my eyes down to find him looking up at me.

"Yes?" I hum back as he shifts to sit up slightly.

"There's four elements, right?" My son asks suddenly and I already have a sinking suspicion I know where this is going. I nod my head slowly.

"Yes, that's right. Do you know what they are?" I ask lightly, trying to assess how much he knows.

"Water, earth, fire and air." He rattles off with surprising ease for his young age. I nod my head and ruffle his hair.

"Yes, that's right." I say with a proud smile as he beams up at me.

"You're a waterbender Mama." He points out and again I find myself nodding.

"I am." I confirm and watch as he sits up properly. I find myself propping my head up with my hand to see his face better.

"And Mr Yun is an earthbender, like Auntie Toph. Grandpa and Uncle Sokka don't bend. Uncle Zuko is a firebender." Yatsu lists off with his fingers as I listen silently. "Mama, why have I never met any airbenders?" Yatsu ends with. I furrow my eyebrows, surprised at the question he ended up choosing, but it's a fair point. I purse my lips in thought.

"Well, airbenders are quite rare. There aren't many of them around compared to the other types of benders." I explain briefly, but it doesn't seem to satisfy the boy's curiosity as he shifts to his knees.

"Why's that Mummy?" My son asks with wide eyes. I chew my lip, wondering how much I should tell him, but finally relent with giving him the full picture, especially since it runs in his blood.

"Lots of reasons. One of them being that their Air Nomad culture means they don't usually get attached to worldly things, so having children isn't high on their priority list. Plus, Air Nomads tend to keep to themselves and stay out in the country or quiet areas instead of the city." I explain as the boy leans in with brimming interest.

"What is the other reasons Mummy?" Yatsu asks while bounding up and down lightly on the mattress. I bite the inside of my cheek.

"Well, there are less...pleasant reasons that stem back in history. Airbenders were arguably one of the more powerful benders which led to other nations trying to wipe them out many, many years ago. That's ancient history of course, but..." I stop myself from saying my next words. 'It's why any tragedy involving airbenders are particularly awful.' I finish in my mind. "...plus, all Air Nomad citizens are benders, unlike citizens from other nations where you can be a Water tribe citizen without being a bender, like my Dad and brother." I add in an attempt to shift the focus away from the sad history. I eye Yatsu's subdued expression and kick myself for being a bit too truthful.

"That's terrible Mama. They didn't deserve that." My son chokes out with a trembling lip. I widen my eyes and go to hold him.

"Hey now, don't be sad. It was a very long time ago. Back when wars were more common." I try to reassure, but the boy stares at me with glassy eyes.

"Don't you think it's bad though?" The boy asks and I find myself swallowing.

"Of course it is, that never should've happened." I agree earnestly. The child bites his lip in a fashion so similar to me that it's almost uncanny.

"Mama...am I...am I an airbender?" His voice is delicate, fragile even, as he flickers his gaze up at me. His serious, pale face, large ears and circular shaped eyes is like looking at an old photo. I forget to breathe for a long moment and when I do, I struggle not to gasp aloud so as to not startle the child.

"I...I'm not sure. After what happened tonight, it's not... impossible." I struggle to force the words out and it's clear that I'm dodging the question. Yatsu doesn't say anything for a long while, but when he does, I almost wish I had shut down this whole conversation from the start.

"Was my Dad an Airbender then?" The query is direct, open and honest. All the things that I'm struggling to give him right now. My breathing catches and I have to push myself into a sitting position just so that I can breathe normally again. "Mummy?" Yatsu probes worriedly when I don't reply. He starts shaking my arm and I realise it's because my breathing has become ragged and uneven. I cough, but it does little to help. "Mama!" My son yells as he clutches my hand tightly in fear. That snaps me out of my funk as I go to squeeze his hand.

"Sorry, I...I zoned out for a moment." I apologise and stroke his cheek when I notice he's still staring at me anxiously. I clench my jaw. "I think we should go to sleep, it's really late." I excuse, dodging the question and the boy visibly deflates as his shoulders slump forward. It's so strikingly familiar and it hits me a moment later why when I realise my ex-husband had the exact same expression and behaviour when I talked to him earlier today.

I struggle to hold in my nausea, but somehow, I'm able to wait until the boy is fast asleep and slip out of the bed and then the room. I make a beeline for the nearest bathroom and vomit up my dinner into the toilet. I hear a light knock at the door, but make no move to open it. Several moments later, I feel a hand on my spine, rubbing circles into the muscles.

"Katara, are you ok?" Yun whispers as he kneels beside me. I turn to give him a wobbly smile.

"Fine, just annoyed that Sokka totally jinxed my kid." I mutter. The doctor blinks in confusion. I sigh. "Why did he have to be an airbender?" I groan aloud as I lean my forehead against the toilet seat.

"Are you positive?" Yun questions as he shifts to my line of sight, his face looks almost as worried as mine. I exhale heavily.

"I mean, no other element would cause him to fly several metres up in the air." I fire back sarcastically, but the man simply quirks an eyebrow at me. I sigh. "Shooting upwards after a sneeze is a classic airbender trait. My...ex-husband used to do it all the time. Plus, when I was waiting for Yatsu to fall asleep, he was snoring and with each exhale the lamp would tip over, I had to put it away." I explain while biting my lip.

"I...see. You don't look very pleased about it." My fiancé comments and I shoot him a glower.

"Of course I'm not! This gives him more questions to ask about his Dad and..." I trail off to massage my forehead.

"And?" Yun prompts with furrowed eyebrows. I breathe out heavily.

"Airbending at a young age is dangerous. It isn't like the other elements. Firebenders usually don't bend until they're a bit older. The worst a young earthbender can do is make some pebbles tremble. Even a waterbender, nothing really happens except some shaking of nearby water. But an airbender? They can put themselves in dangerous situations like Yatsu was in tonight, worse even because air is such an abundant element. It's in everything we do. It's why Air Nomad children are either placed in an orphanage under the tutelage of experienced seniors who can teach them early on to control it or they're kept with their parents if they're very capable masters." I explain as run hazard fingers through my air with increasing anxiety. Yun parts his lips in disbelief.

"How do you know so much about this?" The man asks with wide eyes, but I shrug.

"I was married to an airbender, I picked up a few things about the culture out of curiosity." I reply nonchalantly just as Yun purses his lips.

"So, you think Yatsu could seriously hurt himself? That's why you've decided to stop him from going to school tomorrow?" He queries with a frown and I nod, only for him to shake his head. "Katara, you can't just stop him from going to school indefinitely. You need to get someone to teach him so that he knows how to keep himself safe." My fiancé advises seriously, but I release a humourless laugh.

"Someone to teach him? Other than my ex-husband I've only ever seen one other Air Nomad in my life and that was years ago. If he was just a waterbender then this would all be ok." I complain as I clench my hand, but Yun is quick to rest his hand over mine and the tension leaves my body.

"Katara, you need to talk to Aang." He states firmly, I jerk backwards in shock.

"What? I thought we were trying to avoid-" I start, only for the consultant to cut me off.

"This is for Yatsu's safety. Nothing is more important than that. Besides, if we're really planning to get married, then we need to be ready to overcome any obstacle that comes our away which includes ex-partners." Yun utters seriously. I bite my lip, hating that he has a point.

"Why did you have to be right?" I mumble as I drop my head onto his shoulder. The earthbender chuckles as he wraps an arm around me.

"I am the consultant between the two of us." He jokes, only for me to snort.

"That's only because you didn't have to be pregnant and go on maternity leave." I retort, eliciting a loud laugh from the man. I wait until he quietens down before speaking up again. "I really don't want to talk to him though." I confess as something flutters inside me. He sighs heavily.

"I know, but you don't have to tell him anything. It sounds like he wants to be on your good graces. Maybe he can just give some tips and that will be enough." Yun suggests hopefully and I give him a small smile.

"Yeah, maybe that will be enough." I agree, but a part inside me, the logical part, knows that things are never that simple.

A/N: So Yatsu is an airbender, a couple of you called it beforehand, so not much of a twist I'm sad to say, although kudos to those who guessed it. But don't worry I'm saving my famous Brisalad twists for later down the line (laughs manically) XD Earthbending loses the value of the house…ok ignore my crazy idea to get round the fact that Yun could've easily earthbent the boy down heh. Can't wait for you guys to see the next chapter! See you all in about a week or so!
