Chuck woke up feeling like he had been hit by a truck. His stomach churned as if he were on a boat. Slowly sitting up, he carefully sipped some water to rid his mouth of the taste of bile. He headed to the bathroom, rummaging through the cabinet until he found his savior: Pepto Bismol. He chugged it down, grimacing at the chalky taste. He brought the rest of the bottle back to his room and got dressed for work.

"Chuck! I made pancakes!" shouted Ellie.

Chuck swallowed hard as he walked into the kitchen.

"Thanks El, but I gotta run," he said, sending his sister an apologetic look and hurrying out the door.

The bottle was almost empty as Chuck rested his head on the Nerd Herd desk instead of joining Morgan for lunch.

"Chuck!"

"Ahh!" cried Chuck, falling out of his chair. He climbed back to see Agent Sarah Walker laughing at him.

"God, Sarah, don't sneak up on people like that,"

"Chuck, you were staring right at me when I walked up," she replied, leaning on the counter. "You were in your own little world."

Chuck made a disgruntled noise as he laid his hands gingerly on his stomach, trying to rub it without Sarah noticing.

"Anyway, we have a new mission," Sarah whispered. "Let's go."

"We just finished a mission last night," Chuck whined as he grabbed his coat, carefully slipping the pink bottle into the pocket.

"New day, new mission," said a gruff voice.

Chuck grumbled as Major John Casey herded them over to the Castle.

"A new Fulcrum crime ring has popped up in South Burbank," said the general over the big screen.

She put up a picture. "This is the leader, Victor de Marco…"

The general's voice faded out as Chuck flashed on the picture. As images ran through his head, a wave of nausea crashed into him. Just as he came out of the flash, Chuck grabbed the desk trashcan and vomited into it. Sarah rushed forward to rub his back as Casey made a face and stalked off to get Chuck a cup of water.

"I flashed," gasped Chuck. "There is a party tonight at 1384 South Mulanix in South Burbank."

"Thank you, Agent Bartowski. Agent Walker and Major Casey, I will see that you get into that party tonight. And Chuck?" He looked up from the cup of water he was sipping. "Go home and rest." The screen went blank.

"Come on Chuck, let's get you home," said Sarah, handing Chuck the trashcan and leading him out to her car.

Chuck laid his head back against the seat, feeling worse that he had ever felt in his life.

When they finally arrived at Chuck's house, Chuck was vomiting again. Ellie was just unlocking the front door.

"Ellie!" Sarah called as she opened the passenger door.

Ellie looked up and hurried over to the car, helping Chuck inside as he retched. They lead him to the bathroom and let him be.

"When did this start?" asked Ellie, bringing the soiled trash bag outside.

"He – we were at the Orange Orange when he started vomiting," replied Sarah, sitting on the couch. "This is the second time he has vomited in 15 minutes."

"Did he seem sick before?"

"Not really. He seemed a little zoned out at work, but that's not unusual."

"It started this morning," said a rough voice.

Chuck was leaning heavily against the wall. The girls helped him to a chair.

"I woke up feeling like this. I've been drinking Pepto all day."

Ellie placed her hand on his forehead. "No fever. Did you eat or drink anything bad last night?"

"I had some wine at Sarah's last night," lied Chuck, as he remembered last night's mission. He had only had one glass of wine. His eyes caught Sarah's, who looked extremely worried.

"Um, Ellie, can Chuck come to my place tonight? I could keep an eye on him while you and Devon are at work."

Chuck began to protest, but Sarah shot him a look.

"That's actually a good idea, Sarah," mused Ellie.

Sarah followed Chuck into his room as he grabbed some clothes.

"What are you thinking Sarah?" asked Chuck.

"I'm thinking someone is trying to incapacitate our greatest asset: you."
