Izzy sighed and tried to pull the blankets back from the lump in the bed but he was determined to keep them.

"Alec, you can't have all those blankets you have a fever."

The lump barely moved and Izzy had to strain to hear the mumble that came from under the mountain of blankets.

"I'm cold."

She sighed again and sat on the edge of the bed.

"I know, you're sick right now. Come out of there, you'll smother yourself. I have a potion for you to drink. It should help get your fever down."

She pulled the blankets back to reveal messy loops of black hair. She smiled a little and ran her hand through the tangles, making her brother shiver as he curled tighter into a ball of fevered limbs.

"It's cooold!" He whined, wanting back under his blankets, but Izzy pulled them back to allow Alec's pink nose and rosy cheeks to peek out.

"Drink." He grumbled but came out long enough to drink the bright blue liquid before huddling back under his blankets.

"No Alec, you can't have all of them. We're trying to get you cooled down and staying under five blankets is not going to help. You'll cook like a chicken."

He giggled to himself. "Like a gay chicken, hehe."

Izzy snorted and patted the blankets where his head was hiding.

"Yes Alec, like a gay chicken."

Jace walked in then, holding a bowl of soup and some crackers, and he wrinkled his nose at the overheard words.

"What exactly are you two talking about?"

Alec shuffled around in his bed at the sound of his parabatais voice.

"Jace? Did you get rid of them all?"

Jace set the tray of food down and rolled his eyes.

"Yep, every last one. No spiders are getting to my big brother any time soon, I promise."

Alec snuck a peek, diving back under with a squeak of terror.

"You missed one."

Jace held back a sigh, closing his eyes and taking a breath before opening them and replying in a patient tone.

"Where is it?"

Alec didn't come out this time, only throwing an arm out the side of his bed to point in the direction of his bookshelf.

Jace stomped around a bit, theatrically stomping down the imaginary spiders. There was no point telling the sick shadow hunter he was hallucinating because in Alec words "well they're still pretty damn scary."

"All done?"

Alec peeked before sighing in relief.

"Yup, all gone. I don't like spiders"

Jace picked the try back up, nodding.

"I know buddy, but they're all gone now. How about you sit up so you can have some of this soup I made you. It's Tomato and bacon, your favourite."

Alec sat up but pulled the blankets to his chest, shivering as his shoulders met the air.

"Thanks Jace, you're the best little brother ever. Apart from Max but you're adopted so it's like a whole different category."

Jace laughed as he carefully placed the tray on Alec's lap.

"Thanks Alec."

The boy started on his soup, dipping his crackers in it the way Izzy had always said was disgusting. Once finished, he went to lie down again but was stopped by his little sister.

"Hey, drink this first. You need to stay hydrated."

Alec groaned at the glass of water she was holding out to him.

"I just had soup, Iz, I think that's hydrated."

She shook her head as Jace smiled at how petulant he was being.

"That doesn't count."

Alec scrunched his nose and narrowed his eyes.

"I don't want it, I want to lie down and you've been making me drink all day."

Izzy glared at him with her best 'stern' look.

"Alexander Gideon Lightwood-"

Alec cut her off and reached for the glass.

"Okay, okay. By the Angel, Iz, you're worse than mother."

He took the glass and begrudgingly drank it as Jace snorted at his siblings' behaviour.

Izzy took the glass and handed the tray back to Jace before laying a hand on Alec forehead.

"Your fevers coming down, you'll start to feel better soon."

She kissed his pink nose and started to tuck him in as he lay down.

"So I can keep all my blankets?" Izzy smiled at her bothers small hopeful tone.

"Not a chance big brother."

He whined again as another shiver rolled through his large frame.

"Magnus lets me have lots of blankets. Where's Magnus?"

Jace helped Izzy pull a few layers from the bed, folding them away and smoothing out the wrinkles in the remaining blankets in that pedantic way of his. He swept through the room, absentmindedly putting his brothers things away from where they were strewn about the floor.

"Chill, man, he'll be back soon. He's just grabbing some stuff from his place that you apparently left there." He grabbed another shirt from the floor and started folding it before getting a whiff of it and throwing it towards the doorway, to the growing pile of washing.

"By the Angel, Alec, would it kill you to clean up every once in a while? How do you live in this mess?"

Alec coughed into his elbow and winced at his sore throat as he frowned at his brother.

"It's my room, I can do what I like."

Jace continued tidying, trying to put some sort of order to everything. He wanted to help look after his Parabatai and doing something useful with his hands made him feel better about everything and less like he was in the way.

"That's not how it works, Alec, you can't have your room like this. It's a mess, how do you find anything?"

Alec coughed again and Izzy placed a hand on his back as he caught his breath. He pointed around the room.

"Dirty clothes go there, and clothes that I'm going to wear again go over there. Shoes go under the bed so I can take them off quickly and- hey, leave that alone, I'm not done with it yet."

Jace threw up his hands and put the book from the floor, onto the bookshelf.

"Why don't you just put your clothes away, then you'll always know where they are."

Izzy sighed and closed her eyes in frustration.

"Would you two please stop arguing? Jace, don't tell Alec what to do." Alec smiled and looked smug, until Izzy looked at him with eyebrows raised.

"Alec, let your brother clean your room."

The two wrinkled their noses at being reprimanded by their younger sibling.

Alec looked ready to protest again but was interrupted by his own coughs. "How come he gets to-?" His coughing was deep and rib rattling, left over from the frigid water that he'd inhaled in that frozen lake. Izzy placed a hand on his back and rubbed soothingly as the boy bent double trying to drag in air.

"Is that my Angel?"

Alec's head snapped up and he smiled through the last of the coughing fit.

"Magnus!"

The warlock walked in, coat ruffling as he strode in with quick steps. He dropped his bag onto the floor and sat on the bed next to his boyfriend, taking his flushed face in his hands.

"Oh my poor darling, your fevers not gone down yet. Are the spiders all gone?"

Alec smiled, his eyes glued to Magnus' cat ones. He loved the warlock's natural eyes and had begged him not to glamour them anymore. The boy nodded, his face still cradled in his loves hands, thumbs running gentle lines across his cheekbones.

"Yeah, Jace got rid of them for me."

Magnus smiled back, seeing the fever glaze over Alec's beautiful eyes.

"What a lovely brother he is."

Alec agreed and leant forward to hide his face in the warlock's neck, cuddling into him as Magnus wrapped his arms around the shadow hunter. Magnus hummed as he rubbed his hands over the boys back, making Alec curl tighter to him.

"Are you feeling any better?" He turned his next words to Izzy. "Did he eat anything?"

She nodded, smiling at how puppy-like her brother was being, his hands curling to Magnus' waist.

"He had some soup and crackers and I got him to drink some more water as well as some of that potion."

The downworlder nodded and turned back to Alec.

"Good job, sweetie. Sounds like it's time for bed then, you could use a few more hours of sleep."

Alec shook his head and mumbled words into Magnus' skin.

"I'm not tired."

Magnus rose his eyebrows and bent a little to pepper kisses over Alec's hair and face.

"Oh really?"

Little blue sparks came from every kiss and Alec started giggling and trying to swat his boyfriend away.

"Maggie!"

Magnus laughed and kissed Alec's nose, making him scrunch it in that adorable way of his, before kissing his smiling lips, whispering puffs of blue magic into his mouth.

"Sleep."

The magic did it's work, sending the shadow hunter to sleep with a pleased sigh. He slumped against Magnus, the warlock effortlessly positioning himself in time to catch the boy and lay him gently on the pillows, tucking him in with a last kiss to the forehead.

"You're much better at babysitting him then we are." Jace laughed at the dopey smile on Alec's sleeping face as he patted Magnus' shoulder.

"He looks so cute." Was all Magnus replied with, sweeping his hand through Alec's hair.

Izzy replied with "he does" at the same time that Jace said, sarcastically, "as a button".

Jace picked up the food tray and sighed.

"I've been killing imaginary spiders all day so I'm gonna take a nap. Are you good with him?"

Magnus nodded as Izzy yawned.

"You two have a break, I'll take care of this one."

The two left, leaving Magnus to watch over his charge, with adoring eyes.

"Goodnight angel."
