Bucky pressed the inside of his wrist to Baz's forehead and she pushed it away immediately.

"Leave it, Buck. I'm not sick."

"Okay, Bazzie. You just seem out of it today."

"That's probably stress. I have a pile of unfinished paperwork in my inbox."

Baz coughed a little and Bucky rolled his eyes. He knew she was sick and she knew she was sick, but they also both knew that Baz could easily beat Bucky in a fight, so Bucky elected to stop talking about it.

Baz was pacing around her brother's living room when it happened. She started to feel dizzy, so she sat down. The stack of paper in front of her blurred and she quietly dropped out of consciousness.

Tony whistled a cheerful tune as he walked into his living room. The whistling suddenly stopped when he saw Baz passed out on his couch. He hadn't been expecting a visit from his sister and she seemed to be in really bad shape.

He hurried over to her, skirting the glass coffee table's sharp corners. Tony stood in front of his sister, legs pressing her legs together so she couldn't kick him or the table, and an arm across her chest so she wouldn't hurt herself if she jolted up suddenly.

He used his free hand to shake Baz's shoulder.

"Baz. Baz! You okay?"

She didn't open her eyes, instead moaning softly and mumbling something.

"What was that?"

"I feel like shit."

Tony turned around and spoke to the still air in the room.

"JARVIS, call Bucky."

"Yes, sir."

Bucky felt his cell phone buzzing against his chest, so he pulled it out of the inner pocket of Baz's favorite one of his many leather jackets.

"Barnes."

"Hey Bucky, it's Tony. Baz is passed out on my couch and she just told me she feels like shit. She's-she's got a fever and she's shivering like no tomorrow. Get over here. Now."

Bucky snapped his phone shut (like Tony, he preferred his extremely advanced phone to look like a flip phone so no one would steal it) and ran towards Steve's apartment.

Steve and Gia both jumped when they heard the loud, frantic knocking on the door. Steve pushed himself off of his wife and pulled his shirt back on.

He looked through the peephole, smiling when he saw his best friend's familiar face. He pulled the door open and his smile dropped. Bucky looked panicked and scared.

"What's wrong, Buck?"

"I need to borrow your motorcycle. Mine's getting repaired and you were the closest-"

Steve pulled the keys out of his pocket and handed them to Bucky.

"Thanks so much, Steve. I'll update you guys as soon as I find out what exactly is going on."

Bucky had turned to run down the stairs to the garage of Steve and Gia's apartment building when Steve reached out and grabbed his shoulder.

"Slow down, Buck. What's wrong?"

"Something's wrong with Baz. I gotta go."

Steve let him go that time, and Bucky ran down the stairs to get Steve's bike.

Stark Tower was on the other side of the city, and Bucky broke just about every traffic law there was trying to get there. He ran several red lights and ignored the speed limit entirely, knowing he'd get fined for it later but not caring.

He parked sloppily, then raced up the stairs. The long, slow elevator ride would have driven him crazy.

Bursting through the door at the top of the stairs, he scanned the room for Baz until his eyes landed on her. She was still knocked out and she didn't look like she was sleeping peacefully.

"You okay?"

Bucky jumped when Tony addressed him from the other doorway.

"I'm fine. How's Baz?"

"She's running a pretty high fever. And she admitted to feeling like shit. She's pretty bad."

"Shouldn't we get her to a hospital?"

"I called an ambulance right after I called you. You drive like a fucking maniac, Barnes."

Bucky grinned for a second and then walked over to Baz. He flopped down on a couch that was at a right angle to the one Baz was taking up, hoping whatever she had wasn't airborne.

A few minutes passed in silence before Tony sighed and went down the hallway to his office to distract himself. He tinkered with his suit, fixing a dent from the last time he had to kick ass with it.

Then, the paramedics arrived and everything was chaos.

JARVIS alerted Tony that EMS specialists were trying to get in, and he granted them access. He watched on a screen as they carried a stretcher into the spacious elevator and waited to get to the top floor. Suit forgotten, Tony opened the door and let them in.

They efficiently picked Baz up off the couch and placed her on the stretcher, then started to carry her out to the elevator. One guy stayed behind to ask Bucky if he'd like to go with Baz in the ambulance. Tony hurried down the hall and practically materialized in the doorway.

"We'll both go."

"Tony, I know you have lots of work to do. You don't have to come."

"Are-are you joking? Did you seriously just say that to me? This is my sister we're talking about, dumbass. Of course I have to go."

"Okay guys, if you'll just come with me..."

The two men followed the paramedic down to the ground floor and into the ambulance, where they sat down, each taking one of Baz's hands.

The ride to the hospital was uneventful as far as ambulance rides go. The two men who were closest to Baz sat in the back with her in stressed, panicked silence.
