Twins

Not only that, but Rebekah’s children were conceived at the same time by our father Isaac.
Yet, before the twins were born or had done anything good or bad—in order that God’s purpose in election might stand:
not by works but by him who calls—she was told, “The older will serve the younger.”
Romans 9:10-12

Grapevine = loves gossip, personality like Rarity,
technically the older twin, loves to flirt,
currently working for the Ponyville Times, Gossip Column

Creator's idea for the pony
Name: Tori-nado with tornado heart cutie mark
My idea = on the storm squad
helping control the paths of storms
can fly as fast as a tornado
*318 mph
*512 kph
*like pinkie pie

from a distance the twins looked exactly alike
until Vine cut her tail short
both sisters have the exact same mane and tail genes
Vine styles hers daily
Tori leaves it be : )
