"Oh my Celestia..." The lavender unicorn gasped, "You're an alicorn..." The pink earth pony gasped dramatically, bouncing around the alicorn in circles, rambling about throwing a welcome party, what flavour of cake does the alicorn like and so on. The white unicorn scrutinised the alicorn, not saying anything as if the gears in her mind are working for any flaws in the alicorn's appearance. For positive intentions, not to bully.
"Now hold ya' horses sugarcube." The orange earth pony said in a southern drawl with a suspicious tone, making the pink earth pony stop bouncing, "Ain't Princess Celestia, Princess Luna, and Princess Cadance were the only known alicorns?" The blue pegasus nodded her head, getting into the alicorn's face as her wings beat the air, "Yeah! How do we know you're just not a phony?" The rainbow haired pegasus said, before a shy voice softly stuttered out, a yellow pegasus says softly, "R-Rainbow Dash, don't be rude."
