A/N: Hi! This is just a weird idea I had a few days ago. First fic, so it would be really appreciated if you did not flame. And I know the arguing scene is weird, but it will be explained later! So, without further ado: Chapter One of The Switcheroo!

It was an ordinary day at the SFPD, and Mal and Natara had just found a potential suspect for their latest case.

"Let's go see if Amy has this guy on record, okay?" Natara suggested, smiling.

"Sure."

The two of them strolled down to the lab, and before they could step in, Blaise rushed up to them.

"Mal, Natara, if you value your sanity, LEAVE! Kai's making us do another dumb script reading.

"Gotcha." Mal replied. "Thanks, Blaise."

Suddenly, an irritatingly excited voice rang out. "Oooh, Maltara's here! Great! Just in time to star in the latest installment of 'Hot Frisco Nights!'"

"Kai, there have already been fourteen installments of 'Hot Frisco Nights!' I mean, really, how much longer are you gonna drag it on?" Mal snapped.

"Until whoever killed the wealthy Weatherbee family is brought to justice! Duh! "

"But it's gotten so out of hand that next you'll be telling us a human didn't kill the Twetherfees at all, and it was an alien from Pluto!"

Kai did his best "scary" voice. "Are you questioning my awesomeness? Don't question my awesomeness!" He perked up and handed everyone stacks of paper. "These are your scripts."

Natara flipped through hers. "Kai, just to be clear, no one is doing the unrated scenes."

"Awww, C'mon! Please? Pretty please? Pretty, pretty please with Bunsen Burner S'mores on top?" He begged.

"No!" Everyone shouted in unison.

"Fine! Annndddd...ACTION!"

Ten minutes later, the impromptu play was interrupted

"CUT! Nononono!" Kai shrieked, throwing his arms out. "Blaise, the line is: 'The victim was killed at a fancy seafood restaurant! Something smells...fishy!"

"That. Is. Exactly. What. I. Said." She retorted.

"No, you said 'The victim was killed at a fancy seafood restaurant...Something smells fishy!'"

"Same difference!"

"Is not!"

"Both of you, cut it out!" Natara commanded. "We're supposed to working, not acting out this stupid script!"

"His script isn't stupid!" Jeremy defended Kai.

"Since when do you stand up for him ? I thought we established that we all hated Kai!"Mal yelled.

"Well, you gotta respect the guy. At least he told Kara how he felt about her, instead of moping around feeling sorry for himself whenever she got a date!"

"Oh, you did not just go there!"

"I went there!"

While everyone was arguing, Amy noticed a strange odor. "Guys, stop it!" She shouted. "Do you smell that?"

Blaise sniffed, then nodded. "Yeah, smells like sulphur...rotten onions...sour milk, and..."

"Horse manure." Natara finished assuredly. The next second, her eyes travelled down to floor beside the desk Kai was sitting at, where there was a broken beaker and a slimy green liquid. She pointed at it.

"Kai what was in that beaker, exactly?"

Kai glanced down, and chuckled nervously. "Heh, uh, funny story...I'm...not totally sure."

"KAI!"

"Relax, peoples! I'll just put on the fan, and in the meantime, we can finish the script!"

"I'm not so sure about that. Does anyone else feel dizzy?" Amy asked.

"Now that you mention it, yeah." Jeremy admitted.

"Then we need to get out of here." Mal muttered. "Now."
