Twilight and friends freak out when they hear that a stallion lives alone in the Everfree. They want to "bring him to safety" (and possibly herd with them). He wants to stay as far away from them as possible. When he runs for the hills, he knows they'll follow.
What he doesn't expect is that they'll continue to follow, and follow, and follow...
Very bad RGRE. Don't treat this like actual RGRE, because this is a hot mess.
