Pinkie Pie and Rainbow Dash have been dating for six months. Usually an occasion like that would be the perfect reason for a party, but the pink pony asks Rainbow to keep their relationship a secret.
What used to be a curious request to keep it a secret has now become nagging doubt that hangs over their relationship.
Rainbow is left wondering why Pinkie wouldn't want anypony to know.

This story is mostly just an excuse to write fluffy Pinkiedash.

“Polyamory.”

Rainbow Dash blinked at Rarity. “Come again?”

“Polyamory. What you’re trying to build with Pinkie Pie and Fluttershy is called a polyamorous relationship."

“Okay,” said Rainbow Dash, “fine. So I know what it’s called. But what I really need to know is how I’m going to make it work!”
