A/N: First fanfic. This is more of a side project to another more serious RWBY solo fanfic I am creating but I thought 'why not make this crossover?!' Only the RWBY characters will appear in this chapter. Next chapter is when "worlds" start crossing over. So read, review, and I hope you like it. *fingers crossed* News on main project coming soon.
Disclaimer: I DO NOT own RWBY, Jessie, Sam & Cat, and Breaking Bad. Those belong to Rooster Teeth, Disney, Nickolodeon, and AMC, respectively.

Chapter 1: What could go wrong?

Beacon Academy, Potion & Dust Class, last period of the day

It has been a few weeks since Blake ran away (for a short time) and the fight between Roman (for a second time), and now things are back to normal for Team RWBY, or based on thier definition of normal.

Ruby Rose, the team leader, is sleeping while Weiss Schnee, teammate and Heiress of the Schnee Dust Comp., is taking notes on Prof. Gynda Goodwitch's lecture (no surprise there).
"Now for those who remember, dust is a very useful resource but it could be dangerous if used improperly" Glynda says to the class before spotting Ruby sleeping. She approaches Ruby, with wand in hand, and calls her name, "Ruby Rose". No response. Weiss tries to wake her up "Ruby!" Nothing. Gynda tries something else. She smacks her wand next to Ruby which causes a loud "Eck" from Ruby and wakes her up.

"Wha..Wha..What happened? Where am I" she asks to anybody. Glynda responds, calmly, "You are at Potion and Dust class and you should pay attention, because this class could save you life. If not, well, the exact opposite." Ruby didn't respond as Glynda went back to lecturing the class. "Don't even think about it," Weiss says as she stops Ruby from falling asleep. Ruby grunts and in her thoughts, 'Can't I sleep in peace?'

At the Team RWBY Dorm

Ruby and Weiss arrive as does Blake Belladonna ,the cat faunus teammate, and Yang Xiao Long, the team hothead and Ruby's older sister.

Yang is the first to speak to her sister, "So, Ruby, how was.." "BORING," Ruby grunts. Weiss is the first to respond, "Am I the only one not surprised by this?" Nobody answeres as Blake is reading a book.

Ruby speaks out, "I mean what's the point of notes," which apparently offends Weiss as Ruby continues, "all you do is put some stuff and there, you get a potion." Weiss then rebuttals, " Ruby, do you even remember what happened the first time we met?" Blake tries to hold a giggle as she hears this. "BLAKE" shouted Ruby and Weiss in unison. Ruby continues her argument, "Ok, but it was an accident. You started to shake the bottle and I sneezed then we exploded." "That's my point, you dunce," Weiss retorts.

Yang then breaks up the argument before it gets ugly, "OK, OK, that's enough you two. Let's all calm down and something fun for the rest of the day, like uh..." Blake is suspicious of what Yang might say, "Like What?" Yang smiled as the rest of team RWBY looked at Blake."Don't even think about-" but before Blake can finish, Yang had covered Blake in dust infused kitty litter. Blake's pure cat instincts kicked in as she started acting like a cat, even licking her own hand. Weiss just asks, "How did you make that?" "Made it myself", Yang responds but then a thought pops into Ruby's mind. 'She did that all by herself! Hmmm. What if I make a potion and that I'll show Weiss that I, Ruby Rose, was right after all.'

Yang pulls out a laser pointer as suddenly, Blake chases after the laser. Yang points the laser at the wall which Blake crashes into. This results in everyone (including Weiss) to laugh. They take the fun into the hallway as Blake unexpecteldy crashes into Jaune Arc, Team JNPR leader.
"What the.." Jaune asks in confusion as Blake is chasing the laser. Yang and Weiss follow, but Ruby is left alone with Jaune, still thinking on her "brilliant" plan. Jaune asks, "How did they..."
"LONGSTRORY, CANTTALKGOTTAGOSEEYABYE," shouted Ruby as she speeds to go somewhere else. "Jeez, what's with her," Jaune asks as he just shrugs his shoulders and walks into his team's dorm.

Team RWBY Dorm, Night time

Weiss and Blake are sound asleep in thier beds as Yang is in the restroom. Ruby, however, is not even in the room. Yang comes out of the restroom still in her casual clothes and shotgun gauntlets equipped. Before she can start changing, she suddenly notices that Ruby isn't in bed. "What the.. wow we really say that a lot," she mutters silently. She thinks 'What could she be doing at night.' She thinks about why her sister would still be awake at this time. She suddenly remembers that she said the she made the dust infused kitty litter and the argument earlier in the day. She puts two and two together and...

"OH NO!" Yang whispers to herself as she runs out the door, closes it, then sprints to the Potion and Dust classroom.

Potions and Dust classroom, night time

Ruby has grabbed a bunch of indgredients, beakers, and a pot from the classroom and put it on a table. Ruby smiles and says, "Alright, let's do this!"

She starts to mix stuff into the beakers though ,miraculously, still hasn't blown up. She puts all the mixed elements into the pot, all but one. Ruby grabs a bit of red dust (obvious why she chose red) and is about to put in the mixed potion until.."RUBY!"

"Huh what," Ruby says as she sees Yang standing a few feet behind her. "What are you doing here? Why are you here so late? And why are you just doing random mixtures and stuff," Yang asks Ruby. Ruby only responds, "Wait, Wait, before you say anything, I just need this one thing." "WHAT? RUBY WAIT DON'T..." Before she can do anything, Ruby let the red dust fall into the pot. Yang grabs Ruby and covers Ruby to protect her from the awaited explosion.

But it never happens. Yang lets go of Ruby and sighs of relief. "Jeez Rubes, I thought you were gonna get hurt doing this." Ruby ignores her as she is smiling of triumph at what she has accomplished. "YES! I did it..I did it.. I did it.. I did it.. now Weiss is gonna be so jealous." Yang is unsurprised by this. "Yeah, she is. Now let's go before..."

Suddenly, a bright white light starts shinning from the table. Yang asks, concerned, "Ruby, did you... add dust to it?" "Yeah...why," Ruby responds. Suddenly, Yang's face turns from concern to anger as the white light starts to shine the entire room.

"RUBY, YOU ARE SO D..."
"NOT MY FA..."

**WOOOOSSHHH**

The white light engulfs the entire room in white and a few seconds later, the light suddenly dies down.
The room is completely unaffected by this event except...

Ruby and Yang have disappeared!

On the next chapter of Crossed

"HEADS UUUUUUUUUUUPPPPPPPPPPPP!"

**CRASH**

The kids stood in shock as Ruby Rose crash landed on Jessie. "WHAT THE," asks Luke, "did she just come from the sky?"
