Re: My Little Pony LVI:S Has Left the Playground!
An observation of pony pairs... not that kind.
It seems like the series has been wanting to play sets of ponies off of each other. Rarity and AJ are the hard-working ones that manage to get in trouble by getting too much work and half-truths, but they both of very different views on social etiquette. Twilight and Pinkie make the "Dexter's Lab" pair where you have the bookish genius confounded by a bright but almost alien intellect.
Then why Fluttershy and Dash? They don't seem similar enough for their differences to have much weight. I theorize that trying to answer this has lead to the path of least resistance for the community: Shipping.
