A/N: I had this idea once, I always wondered if Aang had chicken pox once since he can hardly get sick.

It's another day at the Western Air Temple. Katara is all ready up working on breakfast. Everyone else is starting to wake up and gather around with Katara. Katara notices someone missing in the group.

"Does anyone know where Aang is?" Katara asks. Everyone answers to Katara saying that they have no idea. Katara gets up and heads out. "I'm gonna go check on him."

Katara heads to Aangs room in the air temple. Katara takes a peek inside and is surprised to see that Aang is still in bed. Katara walks inside to get a closer look. Aang is sweating and moaning a little. Aang starts scratching his arm in his sleep, then stops. Katara puts a hand on Aangs head, he's burning up. Katara leaves the room then comes back a few minutes later with a bowl of water. Katara lays the bowl on the nightstand. She puts a piece of cloth in the water and gently lays it on Aangs forehead, trying to drop the temperature.

Aang rolls onto his other side, facing Katara, then starts scratching his other arm. Katara looks suspicious to the scratching. Just as Katara was about to remove the cover from Aangs body, Toph interrupts.

"What's wrong with twinkletoes?" Toph asks.

Katara shushes at Toph, telling her to be quiet. "I think he has a fever." Katara whispers.

"What? He can't be sick!" Toph yells. "He was gonna practice his fire and earthbending with me and Zuko."

Katara gets a grip on Tophs shirt then holds Toph in front of her face, even through Toph can't really see Kataras face. "Quiet! He's asleep." Katara yells in a whisper. Katara loosens her grip then returns to Aang. "Just let him rest, I'm sure he'll be fine soon enough."

Toph just turns around and heads towards the door. "Whatever you say, sugar queen." Toph closes the door behind her. Katara just shock her head.

About an hour later, Aang slightly wakes up, only to see Katara is next to him. "Kata...ra?" Aang says, tiresome.

Katara smiles at Aang. "Hey there, sleepyhead." Katara says sweetly, with a little giggle at the end.

"What's going on?" Aang asks.

Katara gently wipes off the sweat on Aangs face with the damp cloth. "It was later in the morning and you were still asleep. I checked on you to find you had a fever." Katara dips the cloth in the water and places it back on Aangs forehead. "How are you feeling?"

Aang starts scratching his arm again. That gets Kataras attention. "Tired and...weak." Aang says.

Katara takes Aangs hand, stopping him from scratching. "Let me see your arm." Katara removes the cover from Aangs upper body then takes his arm. She's surprised to see red dots and some red scratches on his skin. "Have you been scratching these a lot?"

"I don't know...I only remember scratching myself in my dreams." Aang says.

Katara lays Aangs arm down. "I think you have the chicken pox."

Aang looks surprised to hear that. "What? ...I thought I was immuned."

"What gave you that idea?" Katara asks.

"Well, it's just that back at the Southern Air Temple, whenever the other airbenders had chicken poxs, I never caught them. Gyatso thought I was immune to them." Aang explains.

"Well, I guess you've outgrown immunity. I mean, you are a hundred and twelve years old." Katara mentions. Aang starts scratching his arm, then Katara grabs his hand to stop him. "Don't scratch them, it's only gonna get worse."

"I can't help it, it hurts to not scratch." Aang says.

Katara thinks for a moment, then stands up. "I think I have something that'll help." Katara leaves the room.

Katara goes into her room and looks through her bag. Katara leaves her room with a small bowl, then Zuko walks up to her with a bowl of soup.

"Toph told us Aang wasn't feeling well, so I made him some soup." Katara looks at the soup suspiciously then glares at Zuko angrily. Zuko soon realizes Katara doesn't trust him, and now she thinks it's a trick. "There's nothing wrong with the soup, just try it."

Katara takes the spoon and tastes the soup. At first, she smiles lovely as the soup is delicious, then she resumes angrily glaring at Zuko. "Fine." Katara says, taking the soup. Katara walks off, changing the expression on her face. "He's an okay cook, I'll give him that." Katara whispers to herself.

Katara returns to Aangs room, frowning at see him shaking and whimpering. Katara places the soup on the nightstand and looks at Aang. "Are you okay? You cold?" Katara asks.

Tears starts escaping from Aangs eyes. "N-n-no. The itchiness...It. Burns!"

Katara places a hand on Aangs cheek. "Okay. Okay." Katara whispers. "Shhh...just relax. I got something that'll help."

Katara takes out the small bowl. She removes the lid and takes out some cream. Katara gently rubs the cream on the red dots on Aangs chest. Aangs shaking starts dying down as he sighs in relief. "Oh yeah...that's the stuff." Aang says, relaxing.

Katara just laughs a little. "My mother used this when me and Sokka had chicken pox. It really helps." Katara explains, rubbing more cream on Aangs chest. Katara rubs the cream all over Aangs body. Aang starts to relax from the burning pain of the itch. Katara hands Aang the bowl of soup. "Zuko made you this."

Aang widens his eyes in surprise. "Zuko can cook?"

"I know, I was surprised too." Katara says. Aang hesitates on the soup. "Good on, it's delicious."

Aang takes a taste of the soup, then smiles. "Hmm...it is delicious." Aang continues eating the soup, up until he licks the bowl clean. Katara just laughs at the way Aang eats. Katara takes the bowl. "Zuko's an excellent cook."

"I know, I'll admit he is." Katara says. "You feeling any better?"

"Just a little." Aang says. "Thanks for taking care of me, Katara."

Katara smiles. "You're welcome. Why don't you get some sleep. Maybe you can sleep this off." Aang nods then quickly falls asleep.

"Will you stay with me?" Aang whispers in his sleep.

If Aang didn't have chicken poxs, Katara would give him a kiss on the cheek. "Of course." Katara whispers.
