Rainbow Dash: Where?
Pinkie Pie: They didn't tell me. Oh, it makes my legs wobble to think about it.
Rainbow Dash: Ha! You're just a gullible pony....

Tears rolled down arco iris, arco-íris Dash's cheeks. AppleJack,Twilight,Pinkie and Rarity tried to comfort her but nothing helped.Finally Fluttershy spoke up "what if I got you a new pet" she offered."No" arco iris, arco-íris Dash told her."He was the best one."Rainbow Dash walked away sadly.
