"Kid, you look like death warmed over." Plagg complained, floating around Adrien's head as he dragged himself to bed. Two patrols in as many days, and two akumas and a full schedule of photoshoots on top of that, and Adrien was done.

Not to mention he'd caught whatever bug was going around the school.

Speaking of, Adrien's stomach lurched. He clapped a hand over his mouth, motioning desperately for the trash can by his bed. Plagg zipped over with it and Adrien dropped to his knees, cradling the bucket to his chest as bile crawled up the back of his throat. The moments passed in agonizing slowness. Plagg half-turned away as Adrien heaved, slumping over the stinking trash can. Once, twice, three times he heaved, and then he sat, harsh panting filling the silence.

"You good, kid?"

Adrien didn't respond. He didn't trust himself to. If he opened his mouth— another cramp sent him slumping over the can again, dry heaving desperately, trying to get whatever it was out so he could just sleep. Plagg zipped around him, mumbling things that were probably supposed to be helpful, like "You're fine, right?" and "Don't forget to breathe, I think that's important." and "Don't die. I don't want to have to search out another new Chat Noir."

"Doin' my best." Adrien gasped, given a brief moment of reprieve before his muscles took over again and he retched. Plagg settled on his shaking, tense shoulder for a moment before zipping across the room and hoisting the little thermometer Adrien had bought while on patrol yesterday. "C'mere, kid." He muttered, never letting the fear roiling in the pit of his little stomach show.

After all, no one needed to know how many people he'd seen die to "nothing" diseases like this in the past.

Modern medicine, huh?

Plagg pushed the button and waited for the little 'beep', trying to keep the darn thing level against Adrien's forehead. If only the kid would stay still (not that it was his fault that he was throwing up his guts on the floor at three in the morning).

38.5, it read. Low-grade fever. Plagg hummed and Adrien looked up at him through red-rimmed, glassy eyes. "S'mthn' wrong?" He mumbled.

"Kid, you're on the floor dying." Plagg deadpanned. "No, everything's peachy."

"Bury me under the school so I can haunt you forever." Was his holder's oh-so-smart response. At least he was still okay enough to have a sense of humor, however annoying it was. Wait, so what can I do? Adrien let out a choking sound again, throwing himself forward. Nothing came out. Again. The kid's gonna start throwing up his actual guts soon if I don't do something, Plagg decided. He couldn't just call Marinette, unfortunately. That would be an… awkward… reveal. No, thanks to Gabriel, Plagg had to take matters into his own paws.

"Wait here." Plagg decided, phasing out through the window before his holder could protest. The streets of Paris were mostly dark, save for the main drag where tourists still milled about like confused ants. Plagg darted through the shadows, phasing through a brick wall into the drug store. The words were almost all gibberish to him, except for a couple he'd started picking up. Fever was one of them, and he managed to puzzle out which pill bottle he needed to take. Then it was just a matter of making it back to the Agreste mansion (that prison of a house) without being seen.

(There might have been a viral video of a floating bottle from one of the security cameras the next week, but that definitely wasn't Plagg. He was way too careful for that.)

He zipped in through the window, wincing at the horrendous retching sounds still coming from his holder's spot on the floor. "Kid, at least drag yourself to the bathroom." He insisted. "Please?"

Plagg hadn't even noticed that he'd used the 'P' word. If he was Fluff, he would've undone that in a snap. But at least it got Adrien moving. A few minutes later, Adrien was crouched against the shining white toilet seat in his (far too large) gleaming, fancy bathroom, forehead pressed against the smooth porcelain. Plagg dropped the bottle at his feet. "Take one of these. I'll get the other ones."

"Plagg." Adrien rasped, choking back another heave. "Where did you get— those?"

"Doesn't matter." Plagg decided. "Stay here."

"Not going—" Adrien's sassy comeback was ruined by his stomach cramping again, forcing him to sit with his head hovering above the toilet seat.

Plagg took advantage of the silence to dart away, flitting through the darkened halls until he reached Nathalie's bathroom with its medicine cabinet. He grabbed the appropriate pill bottle for settling upset stomachs and darted back to his holder, who was leaned against the wall, head tilted back, staring idly at the ceiling through half-lidded eyes.

"Plagg." He groaned, voice thick and hoarse. "I think I'm actually dying."

"Get help then."

"Nope."

"I'll start planning the funeral." Plagg dumped the second pill bottle at his feet. "Come on. Eat up."

Adrien pushed both bottles away. "I can't."

"Can't what?"

"Eat… anything." He went a shade paler at the word alone.

Plagg pushed them back, darting up and turning on the faucet. "Just try."

"Hang on." Adrien breathed. "It's…" His face contorted again. "… not… over."

"Just let it happen." Plagg advised (in reality, he had zero idea what he was doing). "Tensing up makes it worse."

"Easier said than done." Adrien spoke through clenched teeth, one hand rubbing at his stomach. Suddenly said hand clenched into a fist and he threw himself forward on his knees to the toilet again, choking on nothing and gagging, struggling against his own body as his stomach tried to bring up contents that simply weren't there.

Plagg rubbed at his holder's back, although he wasn't quite sure what that would do. Worry pooled in his gut like a cataclysm. "Breathe, kid."

Adrien sounded like he was about to start crying. "I— I can't— can't this just be over?"

"Let it happen, kid." Plagg mumbled, gut twisting. Why were human organs so damn complicated? "Just… let it out."

Adrien's face contorted again. "Can't—" He gasped, kneading at his stomach with one hand while the other gripped the toilet seat so hard the knuckles turned white. "Plagg—"

"Shhh…"

"Help."

Something in Plagg, some proverbial dam, turned to ash as soon as his kitten said that word. Plagg zipped down to Adrien's stomach, feeling along it until he found the hard knotted part. I really hope this still works, he thought.

"Wh—what?" Adrien gasped, moaning.

Apparently Plagg had voiced his thoughts. "This'll be over soon, kid." Plagg promised, and then he pushed. Hard.

Adrien let out a strangled groan that quickly grew in intensity. Plagg pushed harder, faster, determined—

A wet gurgling sound came from above him and Plagg darted away just in time to avoid Adrien finally heaving up whatever had been hurting him so badly. Plagg could plug his ears, but he couldn't plug his nose, and it was legitimately making him lose his appetite. Nothing made him lose his appetite.

"Take those pills." Plagg called, zipping back inside with a blanket Marinette had knitted for them. (Technically it was just for Adrien, but it was too soft to let go to waste.) A moment later, Adrien set both bottles on the counter. Plagg hid them back in Nathalie's medicine cabinet and then zipped back up just in time to tuck his kitten in, letting him take all the blanket so he could be a little burrito on the floor. Plagg even gave him the clean pillow from their bed.

"Thanks, Plagg." Adrien whispered, very much exhausted. With nothing else left to do, Plagg settled into his little nest that was Adrien's hair, raspy tongue working its way through his holder's sweaty blond locks and making its way down his forehead. He didn't stop until Adrien was fast asleep, and then he didn't stop until the warmth pulsing from Adrien's skin had faded.

It took until by the time the sun was starting to rise for the Kwami of Destruction to finally admit that his kitten wasn't in any danger.

In the morning, Nathalie found a flushed Adrien curled up on the bathroom floor with a poorly knitted blanket and a new stuffed animal in the morning, but she let it slide.

A/N: Everyone always has Marinette care for Adrien, so I figured it was time to give Plagg the spotlight. Also, stealing. Plagg's a cat burglar, it's confirmed.
