A flash of scarlet light went to the back limbs and neck of a regal unicorn. A shriek arose from the gasping alicorn.
"Oh sister, if you won't let me have the sun, I'll kindly take it from you."
"Dash, I hope you know, before you kill me, no come here. I'll whisper it to you." Dash trot over to the sun goddess. "The secret is...." Dash was on the moon again.
"Goddess... the old hag's good. What hag? Why am I on the moon? Oh, Dash ha! Lemme tell you something. Rainbow's eyes went blank. You lost. The voice chided. Deep in her mind, Rainbow Dash saw herself prancing with glee. She looked closer. Flames. They consumed Canterlot. There was nothing left. "Listen bucko." Thought Dash, "I can control myself if I want to. I mean. I didn't kill anyone last cider season."
"Well, I am 20% more cunning than you."
"Hey! That's my catchphrase!"
"We'll you won't be alive for much longer, will you?"
"What the-"
"Never mind that. I'm hungry. Go eat for me!"
"No. Marshmallow, Cotton Candy and the Bacon Bros aren't here."
"We're going to Equestria."
"No wai-"
Poof.

"And that Luna is how-" Luna and Celestia saw a momentarily airborne wrestling match including a black alicorn and another of the species with a six color mane and cyan coat.

"Friggin-Dash are you-shut up!"

"Whoa!"

"Get out of this Luna!"

"Tia-"

"On it little sister" And the shadowy one was on the moon. Rainbow Dash looked at the princess with gratitude. Dash wondered what jealousy would do up there, but pushed away the thought of it. "Thanks biggest sister."

"Don't mention it." And that's what she said with a mischievous grin on her doll like face.

Jealousy

The black pony on the moon was pacing. almost as much as Twilight when upset. "I must find a way back." the pony said aloud. "But... I need a host. Somepony with a horn."

Rainbow Dash was sitting on her loft bed comfortably reading Daring Do and the Quest for the Saphire Statue for the forty-second time. "Sister? is the spirit of jealousy still on the moon?"
Luna pondered the question for a while. "Yes."

Jealousy say grumpily on the spongy night rock. "I can't teleport myself.... but I can teleport others! Right! I know exactly who!" The star pony mustered up all her magic to teleport a lavender mare.

"Wha- Where? who?" Twilight Sparkle was suddenly on the surface of the moon, choking. A black pony was magicing a space helmet to the unicorn.

"Sister. I'm scared."

"Why?"

"I haven't heard from Twilight."

"Nor have I, Rainbow Dash."

"Oh.."

Jealousy had the small mare in her hooves manipulating Twilight with her eyes.

"Now, small pony you will let me use you."

"yes"

"Thank Badness."

Rainbow Dash was feeling uneasy. Princess Celestia swiveled her telescope to the moon. "I see.... Jealousy. That's good. But..." Rainbow did not need to know what was happening. The blue alicorn ran to the shelter. "Send Luna!" Shouted the white godess. The midnight pony sprinted to the castle doors. It would be so much easier if the doors were less than 30 hooves high. thought the pony that was not as alert as she should be.

Jealousy was ready to teleport through Twilight Sparkle. Jealous Twilight shouted, "I'm coming for you, little filly!"

In the shelter, there was a stuffed Pinkie Pie. She yelled "Hi Dashie!"every time you squeeze her. There were about 6 too many "Hi Dashies!" that day.
