A/N: Hi! It's me again. :) This is the sequel to 'Operation: Survive Spring Break'. I'm posting this a lot faster than I thought I would. I didn't realize that it was so close to July already. I hope that I can finish this faster than I finished the last one. I always seem to update these holiday stories a lot slower than my other ones.

Summary: The Cahills go to Amy and Dan's house for July 4th. Dan's playing with fireworks, everyone's trying to get Sinead and Hamilton together, Ian and Dan get stuck in the middle of nowhere, and the Cahills do roleplay. Hamead and Amian.

You just gotta ignite the light...

"Did you have to bring out the video camera again?"

"Are you insane? You're letting him pick out the fireworks?"

"Hey! I resent that!"

"I wish you'd all just shut up."

Fifteen-year-old Amy Cahill sighed as she watched her relatives yell and argue with each other. They had decided to invite everyone over to their house for Independence Day, and Amy had been regretting it ever since. Much to her disappointment, her uncle Fiske Cahill would be out of town for some Cahill business, and wouldn't be back until after the holiday.

"Amy! Tell your brother to put away that video camera!" Belle demanded.

"Dan," Amy sighed wearily. "Put it away."

"But-" started Dan, but Amy silenced him with a look. Grumbling, he turned the camera off. He turned to his sister. "Hey, I forgot to tell you that I invited Atticus and Jake over on July 4th."

Amy frowned. "You couldn't have told me earlier?"

Dan shrugged. "Like I said, I forgot. I didn't think it was such a big deal anyway. It's just for one day."

"Who are they?" Madison asked.

"Atticus is Dan's friend. He met him online," Amy replied. "Jake is his brother."

"Great, more people." Natalie muttered.

Jonah clapped his hands together and grinned. "So, who's picking out the fireworks this year?"

"I am," Dan answered, grinning cheekily.

Natalie scowled. "I don't approve."

Dan glared at her. "Who asked for your opinion, Cobra?"

"I'm pretty sure the Janus did," Natalie retorted.

"Dan can't go by himself," Nellie said, ignoring them. "So, someone should go with him."

"I vote for Ian," Hamilton said with a mischievious grin.

"What?" Ian and Dan exclaimed in unison.

"No way! I'm not going anywhere with him!" Dan sent a pleading glance towards his sister. "He'll murder me and hide me where no one can find my body!"

Natalie scoffed. "Like he'd do that. It wouldn't really help his relationship with your sister, would it?"

"I think it's a good idea," Ted said. "Ian will be able to keep Dan in line."

"Hey!" Dan glared at him. "He's the one that needs to be kept in line."

Ian scoffed. "Hardly."

"Do you really think this is a good idea?" Sinead whispered to Amy as the two Cahills argued with each other.

Amy sighed. "Probably not, but it's true that Ian will be able to keep Dan in line."

Sinead raised an eyebrow but said no more.

Belle stood up. "Well, I'm going to go to my room." She turned to Sinead. "Do you mind showing me where it is?"

"Alright," Sinead and Belle walked out of the living room.

Dan immediately turned to everyone. "Alright, Belle's going to distract Sinead while we talk about the plan."

Hamilton was confused. "What plan?"

Dan grinned. "Operation: Get Sinead and Hamilton together!"

"Wha-oh, that plan." Hamilton grumbled.

"I've already got a plan ready," Dan said. He leaned forward and grinned. "Okay, we're gonna need some costumes, candlesticks, a ballroom-"

"Why do we need that stuff?"

"And how are we supposed to get a ballroom?"

"What Disney movie are we even doing?"

Dan sighed. "Alright, I guess I'll start from the beginning..."

Let it shine...

Belle glanced at Sinead. "So, how have you been, Sinead?"

Sinead looked at her suspiciously. "Fine, you?"

She shrugged. "Good enough." A sly smile appeared on her face. "So, did you get a boyfriend, yet?"

Sinead blinked, surprised. "What?"

"Well, since your break-up with Hamilton-"

"We were never dating," Sinead interrupted. "It was fake."

Belle laughed without humor. "How do you think Hamilton felt? You know he actually likes you, right? He gave you that valentine on Valentine's Day, remember?"

She looked away. "I know."

"Well, what are you going to do about it?" Belle asked.

She didn't answer.

Belle sighed in exasperation. This girl is hopeless. "You all are lovesick fools." Belle muttered under her breath.

Sinead showed no sign of having heard her.

Come on, let your colors burst...

"Hey, Ned!" Dan intercepted him on his way to the kitchen. "Do you know where I can can some liquid oxygen?"

Ned immediately became suspicious. "Why do you need that?"

"I'm doing a science experiment," Dan replied. "Amy's always telling me that I need to take that class more seriously."

Ned narrowed his eyes. "Dan-"

"Really! I'm not kidding," Dan insisted. "We did this experiment last year in class, and I wanted to try it out here." He looked at him intently. "You have to know a place where I can get some."

He sighed. "I'm sure Sinead has some in her lab-"

"Thanks!" Dan started to run out of the house. He stopped for a moment and turned to him. "Do you think Sinead has some really big cotton balls, too?"

After he saw Ned's blank look, he rushed off. Ned shook his head in disbelief. I'm going to regret giving him that information.

Baby, you're a firework

A/N: Ooh, Dan's planning something. XD It took me a while to write this chapter. My computer froze before I could save this and I had to write half of this chapter over again. :( Any ideas for what Dan is planning? I'd love to hear what you guys think. :)
