This is kind of a short story, but not a one-shot or anything. CGI chipmunks! Therefore the age order- oldest to youngest- is Simon, Alvin, Theodore. Don't comment on that in a review please. I know Alvin is the oldest in the cartoon. This is directed a little more towards Alvin and Brittany. Anyway, on with the story!

Chapter 1

The summer carnival was coming up in a few days and the Chipmunks and Chipettes were going to perform there.

It was a normal day in the Seville household. The Chipettes had recently gotten their own bedroom. The girls were all upstairs hanging out in their new room. Simon was working on the computer in the living room, Theodore was watching TV on the sofa, and Alvin was desperately looking for his lucky guitar pick.

"I can't find it!" Alvin cried for the fiftieth time.

"Alvin, would you give it a rest? It'll turn up eventually," Simon said.

"But I need it for the performance. And besides, it's so tiny, it could be lost forever now."

"Did you check our bedroom?" Theodore asked.

"Only a billion times!" Alvin cried, "I swear, I've checked the whole house!"

"What about the Chipettes' room?" Theodore suggested.

"No. But why would it be in there?"

Theodore shrugged, "Maybe, they were borrowing it."

"What! They don't play guitar. Wait, does that mean that they were in our room taking my stuff again! Grrr! I'll be right back," Alvin said storming upstairs.

In the Chipettes' room, Brittany was sitting on the soft pink rug crying her little, blue eyes out. She was making soft whimpering noises as her sisters tried to comfort her.

Alvin marched over just outside the girls' door, but stopped when he heard them talking. He couldn't help it, he had to hear what they were talking about. Curiosity got the best of him.

Eleanor patted Brittany on the back and said gently, "Don't worry, Britt. We won't tell him if that's what you really want."

Jeanette said, "Should we tell Simon and Theodore?"

Brittany shook her head. Eleanor sighed and said, "Well, I guess that messes things up for the performance."

"But what happened to the show must go on?" Jeanette questioned.

Brittany felt more tears roll down her cheeks. Alvin, outside was getting a little suspicious and a little worried. We won't tell him? Was this "him" Alvin?

Alvin knocked on their door.

"It's me!" he called through the wood of the door. He heard some whispering and then Eleanor's voice call, "Come in!"

Alvin jumped up onto a table next to the door, then onto the doorknob and hung off of it, turning it and then opening it.

He walked in to see the girls all sitting next to each other in the middle of the room. Brittany was obviously trying to hide the fact that she was crying. She was wiping her eyes with her sleeve as Alvin strolled into the room. He almost asked them what they were talking about before, but that would give away the fact that he was eavesdropping, so he decided to keep quiet.

"What brings you here?" Jeanette asked.

Alvin answered simply, "I'm looking for my lucky guitar pick. Have any of you seen it?"

"Nope," Jeanette and Eleanor answered in unison. Alvin glanced at Brittany who hadn't said anything. She looked a little sick. He found this as a good opportunity to ask her what was wrong.

"Gosh, Britt. You don't look so hot. You feeling okay?"

Brittany didn't say anything she just nodded.

"Do you-"

"Alvin," Jeanette said interrupting him, "I don't think your guitar pick is in here, but if we find it we'll let you know."

By her tone, Alvin found this as a hint that they wanted him to leave. He slowly exited the room.

"Uh… Okay. Thanks… I guess," Alvin said and then left, closing the door behind him. Once the door was shut all the way, Alvin ran back and pressed his ear against the door.

"That was close. I was afraid he would figure out that something's wrong," Eleanor said.

"You know, we're all living in the same house. He's going to find out eventually," Jeanette said.

Brittany then said something in a very, very soft whisper. So much that Eleanor and Jeanette could barely understand her. Alvin definitely couldn't make it out. Jeanette then said, "Okay. Well, then we'll just keep our lips sealed for now. Alright?"

Alvin's stomach began to hurt. He couldn't imagine what would be wrong. Brittany was fine the last few days. Alvin's thoughts were interrupted by the sound of Theodore's voice shouting, "I found it!"

Alvin dashed down the stairs, sliding down the railing, and into the living room.

"No way! Where'd you find it?" Alvin asked.

Theodore said, "It was between the couch cushions!" He handed the red pick with the golden "A" on it to his brother who just looked down at it with a slight smile, which slowly faded into a frown.

Theodore noticed right away and looked up at him and said sweetly, "What's wrong?"

"Ah… It's nothing, Theo," Alvin said tucking his guitar pick into his hoodie pocket. Simon, hearing the two's conversation, jumped off the desk and joined them.

"I think there's something," Simon said.

"No really. It's no-"

"Come on, Alvin. You know you can tell us anything," Simon said encouragingly. Theodore patted Alvin on the back.

Alvin sighed, "Okay. Well, I'm just a little worried about Brittany. She doesn't seem like herself today. When I went into their room she looked really sick and she wouldn't talk to me and it looked like she'd been crying."

Theodore stopped patting his brother on the back. Simon and Theodore's eyes widened. Simon said, "What is this world coming to?"

Theodore said, "You're worried about Brittany?"

"Oh my goodness! He does care about people other than himself!" Simon exclaimed.

"I told you!" Theodore replied.

Alvin shot them both glares and said, "I'm being serious, you guys! I overheard the girls talking and the only ones talking really were Jeanette and Eleanor. Brittany was being really quiet. They said something about not telling us something!"

"Oh, Alvin!" Simon said putting a paw over his eyes.

"I know! I want to know what they're hiding from us too!"

"No. Not that. I mean, you were eavesdropping on them! Alvin! You can't-"

"I know it's wrong! But look! I'm really nervous right now and you should be too."

Simon said, "Look, maybe it's just one of those things. You guys got into another fight, Brittany says she refuses to talk to you forever, she keeps her word for one day, and then starts talking to you again like it never happened."

"Yeah, but I don't remember her saying that to me. That also doesn't explain why she's so sick looking. And what is it that her sisters can't tell us?" Alvin said as he began pacing in thought.

"Well, they can't keep it from us forever. Let's just let whatever happens, happen. Okay?" Theodore said.

Alvin said, "Oh fine. But I'm not going to sleep until I find out what's wrong."
