When Queen Chrysalis was defeated, she was repelled fairly easily by Shining Armor's shield. Knowing this, everypony involved dropped their guard and went back to their lives.
But did anyone find it suspicious that a changeling that had just defeated Celestia in single combat would be defeated so easily by the very thing they eat- love?
Of course not... after all, the power of love solves everything, right?
Right?

Have you ever heard the tale of the Four Heroes?
Everyone thinks they know the ending. Mario, Peach, and Bowser destroyed the Chaos Heart, and defeated the menace Dimentio.
But was that really the end? Of course not. We wouldn't have much of a story, otherwise.
(The Human tag was put there because Dimentio is kind of human. Maybe.)
(Dimentio is from the game Super Paper Mario. Spoilers for the ending of that game.)
