If was an average day in Ponyville. It also seemed like an average day for the Harvest family. Red Harvest and Apple Orcherd Fritter Harvest were happily married, and they may have been expecting a foal or two.
But things when spiraling downhill when a mysterious mare had arrived at Red's front door. Apple was out, and she was trying to seduce Red. Normally, he would have turned her down and shut the door. But it was only recently he discovered the dirty pleasure that was intercourse, and couldn't resist. He invited her in happily, ready for adult play time.
What he didn't expect, was this mare had a little secret. She had secretly been going around various parts of Equestria, looking for stallions that would cheat on their partners. When she got close enough to Red and knew he would cheat on his wife, she took a knife and stabbed him fifty times in the chest.
Before Apple could get home to discover the mess, she hid the bloody knife and left a note on Red's corpse that said "I did you a favor" After that, she had disappeared, and Red's deceased body lay on the floor, covered in blood.
