Ending 3:[…] Instead of erasing their clothes or crushing them outright it erases their remaining size and the Humane 7 shrink even further!

As the last 2 shrink further then enter the atomic realm and are in short order smaller than a atom. Still shrinking they embrace each other in love and passion. Then Rarity and Twilight shrink right out of sight never to be seen again. […]"
