Rainbow: Go away! You broke my heart!

Bowser: By the way, I figured out what to do with you.

Rainbow: Y-You did? Are you gonna sent me somewhere I won't see my friends again?

Bowser: Not a bad idea, but no!

Rainbow: W-What then?

Bowser unlocked the cell and knocked Rainbow Dash out. When she woke up, she felt hot, she found herself chained to a wall, hanging over a pit of lava

Rainbow: Wh-What're you doing?

Bowser: Oh, good, you're awake! You see that pit of lava down there? You're gonna be in here enjoying the heat while I figure out what to do with that necklace of yours!

Rainbow: It's called a geode, buddy!

Bowser: Whatever. Enjoy the heat!

Bowser pulled a lever and exited the room. Pretty soon, the lava began to rise. Rainbow Dash gulped in fear and teared up. What Bowser didn't know was that the geode's magic wouldn't work unless the owner wore it. If the past incidents she had weren't the end of her, was this it? 

Rainbow: *sniff* Please hurry, guys, I need you!

It was too late to write another note to everyone else, the least Rainbow Dash could do was panic.
