I do not own Alvin and The Chipmunks. Hope you enjoy the story.

Chapter One: The Symptoms

Dave waited by the bottom of the stairs for the boys to come down. He looked at his watch.

"Boys! Come on, we're going to be late!"

Alvin, Simon, and Theodore came down the stairs in nice suites. The Chipmunks were going to a music session with The Chipettes, and all of them were late. Alvin ran up to Dave.

"We're ready, Dave."

"Good. Now let's hope the girls are ready to."

Miss Miller, Jeanette, and Eleanor were waiting by the door for Brittany. Jeanette looked up the stairs.

"Brittany! Hurry up will ya!"

Upstairs, Brittany glanced over by the doorway. She finished brushing her hair and ran downstairs.

"I'm ready."

Miss Miller opened the door and they hopped into Dave's car. The fifteen-year-old kids all sat in the back seat. Alvin and Brittany sat by each other, of course. Only after fifteen minutes, they arrived at the music session.

"All right kids, be on your best behavior."

Simon smiled, "Just tell that to Alvin and Brittany, Dave."

They glared at him. They all got out of the car and entered the music building. The music producer paced nervously. Dave ran in with Miss Miller and the kids behind him.

"Sorry we're late."

"Well, you're not that late. But we do have to get to work right away."

Alvin smiled and ran up onto the stage, "No problemo, Jerry."

Simon, Theodore, and the Chipettes followed Alvin on stage. Dave talked to the producer.

"So you want the boys to start first, then the girls, right?"

"Yes, Dave. Then I want Alvin and Brittany to sing a duet together."

"Sounds great."

The boys started to sing several songs. Jerry wrote in his notebook while Dave was hoping Alvin wouldn't goof off. He was lucky there.

An hour later, the girls got to sing, but not too much longer, Brittany started to feel sick. Alvin was the only one who noticed. He was really worried. Five songs later, Brittany felt worse.

"Can we take a break, please?" she asked the producer.

"Sure."

Brittany put the microphone back on the stand and sat down on the edge of the stage. Alvin sat next to her.

"Are you ok, Brit?"

"No. I've never felt so sick in my life."

Alvin put his arm around her and she rested her head on his shoulder.

"Just rest for a while. Maybe that will help."

"I hope so…"

Everyone else went over to them. Eleanor walked up to Alvin.

"What's wrong with her?"

"She doesn't feel good. She said she hasn't felt this sick ever."

Her sisters went up to her and felt her forehead. Jeanette turned back to Alvin.

"She does feel warm."

Brittany opened her eyes. She lifted her head from her boyfriend's shoulder and rubbed her eyes. Simon looked at her in concern.

"You ok, Brittany?"

"Yeah, I guess so."

The producer sighed in relief, "Great. Then we can continue."

Simon was going to tell Jerry that it wasn't a good idea, but he figured he wouldn't listen anyways. Before the girls sang, Theodore gave Brittany a class of water.

The girls finished their songs. Brittany rubbed her head with her hand and squeezed her eyes shut. She kept feeling worse. Alvin walked on stage with Brittany.

"Do you want to call the duet off?"

"No. I'll be fine. Don't worry."

He slightly smiled. How could he not worry? The producer then sat down with Dave and Miss Miller.

"Ok, you two, do you know 'Nothing's Gonna Stop Us Now?"

Alvin smiled, "Yeah."

"Great! Can you two sing that song?"

Alvin looked over at Brittany. She answered.

"Sure."

They started singing once the music came on. Brittany made it through the song, but she still felt awful. The producer was happy.

"That sounded excellent you two! Just wonderful!"

"Thanks," Alvin said happily.

The Chipmunks and the Chipettes went into the lunch room to relax. This is was what Brittany wanted to do for a long time. She sat at the table and put her head down on her arms. Alvin went over to her.

"I suppose you don't want anything, huh?"

"No."

"Anything to drink?"

"No thanks…"

"Ok…I'll be back soon."

Alvin went to get food. Theodore walked up to his oldest brother.

"She seems to be getting worse. Do you know what's wrong with her?"

"No. She doesn't even know."

Dave turned to Alvin. "Maybe we should get her to a doctor."

"Maybe. We'll see how she feels later."

When everyone was finished eating, they went to the auditorium to just goof around. Except Brittany, she started to feel dizzy. She was scared, everyone was. Alvin looked over at her. She grabbed the curtain from the stage and fell to the floor. Alvin dropped the microphone and ran over to her.

"BRITTANY!"

Everybody stopped what they were doing. Brittany kept rolling and yelling in pain. Simon and Jeanette went to get the adults and Theodore and Eleanor went to get a pillow for her. Alvin stayed with Brittany. She stopped rolling and yelling and just laid there in pain. She squeezed Alvin's hand.

"Alvin…I can't move…" she said softly.

"It's going to be ok," he whispered.

Theodore and Eleanor came back with a pillow. Alvin lifted her head while Eleanor put the pillow under her sister's head. Brittany started to sweat a lot. Alvin turned to his youngest brother.

"Theo? Can you please get a wet wash cloth?"

"Sure."

Eleanor got up, "I'll go with you."

Alvin looked back at Brittany, her eyes were barely open.

"I'm cold…" she said faintly.

Alvin tried to keep his tears in. He took off his jacket and put it on top of Brittany. Then, the adults came rushing in. Simon, Jeanette, Theodore, and Eleanor followed. Miss Miller looked down at Brittany.

"Oh my! What happened!"

Alvin explained it to her as Eleanor dabbed Brittany's face with the wet wash cloth. Jeanette sat on her knees holding Brittany's hand. They both had tears in their eyes. Alvin ran to Dave.
"Dave, call an ambulance!"

"I already did, they should be here soon."

Brittany looked at her sister. She talked to them quietly.

"Where's Alvin?"

Jeanette went to get him. To her surprise, he was crying.

"Alvin…Brittany wants you…"

He wiped the tears from his eyes and went over to her.

"I'm here, Brit. It's going to be ok."

Then the ambulance arrived. The doctors put her on a stretcher and rolled her into the ambulance. She looked at Alvin as they lifted her into the vehicle.

"Alvin!"

"You'll be fine. I'll see you soon."

They closed the door to the ambulance and drove away. Alvin just stood there and watched the ambulance disappear. Dave put his hand on his son's shoulder. Alvin hugged Dave and started crying again. The rest of the kids went inside the studio. Jeanette looked at Simon.

"I've never seen Alvin cry before."

She hugged Simon and he closed his eyes.

"He really likes your sister a lot.

She smiled, "I know. She really likes Alvin a lot too."

Later, Dave gathered everyone together and they drove off to the hospital. When they got there, they all waited in the waiting room, impatiently. After a while, a doctor came out and walked up to them.

"Are you here for Brittany Miller?"

Miss Miller looked up at her, "Yes. What's wrong with her?"

"I wish we could tell you now, but we have to do some tests first, we'll hopefully know by tomorrow."

Dave got up, "Thanks."

"No problem."

Everybody got up and was ready to leave- except Alvin. He walked up to the doctor.

"Would it be inconvenient for me to stay with her over night?"

"No, not at all. As long as your father is ok with it."

He asked Dave and he understood the situation and let him stay. The doctor led Alvin to Brittany's room. A little while later, he was alone with Brittany. She was fast asleep; she was hooked up to a bunch a machines. He held her hand in his.

"I'll be here all night, Brittany. I don't want to leave you."

He kissed her hand and tried to fall asleep and he eventually did. Brittany woke up a few hours later and saw Alvin right by her side. She smiled and fell asleep again.

Well, that's the first chapter, hope you liked it. The next chapter will be up soon
