Okay. That's an overstatement. And you almost gave me a heart attack.

To anyone reading, Applejack is not going to be killed. The team for G5 is considering massively altering her character though so that she's a tough city-girl, brought up with street smarts, etc. They're doing this because AJ's character is hard to write for in a way that facilitates growth. But this is just consideration at the moment and these leaks might not even be legitimate. Or some parts of the leaks might be real while others are fakes put in by trolls to stir everyone into a panic (which appears to be working).
