I'm not kidding. I was watching Bronies React to the Season 3 finale again and i suddenly realized that they'd done a clever bit of foreshadowing with Pinkie Pie.

Think about it, out of all the Cutie Marks she could've gotten during the switch, she got Applejack's Cutie Mark and then, the very next season, we find out Pinkie could be related to the Apples.

Coinsidence? I think not! Brilliant bit of foreshadowing there, Hasbro. Very clever indeed.
