Fire of Two Sisters

"And Spitfire said she would consider me for the Wonderbolts!" Rainbow Dash happily told Twilight, who was haveing lunch with her rainbow colored friend. The cafe they were at was an expensive one, and with Twilight around everything the two mares ordered was free. As the second corse came, Twi replied.

"That's great, Rainbow!" then she joked, "maybe you'll be the princess of speed one day!"

Suddenly Rainbow Dash's expression was uneasy. Twilight looked around to see most ponies bowing to a pale pink alicorn with a firey red mane and tail. She also noticed Rainbow avoiding eyecontact with everything but her plate.

The sound of hoofsteps aproched their table.

"Hello, Rainbow Dash." said the alicorn. Her voice and Rainbow's were almost identical, the alicorn's slightly higher.

"Hi Jed Fire, Princess of Speed, Flames and Dragons." Rainbow replied, not looking up.

"Friend of Yours?" questioned Twilight.

"The day we're friends is the day I admit... It." Rainbow Dash replied, with a tone of hatred in her voice.

"Still wouln't except it, huh Dash." Jed Fire replied.

"Except... what?"

"No!" Rainbow Dash yelled, standing from her seat.“I will not take my rightful place!" And with that, she stormed out of the restaurant.

Twilight quickly hurried after her friend, and Jed Fire followed. Twilight pondered what just happened.

Ok. Rainbow Dash has some right full place, Jed Fire is the alicorn behind me, who I've never heard of, Rainbow knows everything about her, it seems, and has something against Jed Fire. What in the wide wide world of Equestria is going on?
