I found it very sad that PRINCESS CELESTIA, THE PRINCESS OF THE DAY, her sister PRINCESS LUNA, THE PRINCESS OF THE NIGHT, became NIGHTMARE MOON. And CELESTIA banished her to the moon for a thousand years. And one year NIGHTMARE MOON came back to EQUESTRIA. And then NIGHTMARE MOON was defeated by TWILIGHT SPARKLE and her very first FRIENDS with the help of THE ELEMENTS OF HARMONY. And then PRINCESS CELESTIA, THE PRINCESS OF THE DAY came back to EQUESTRIA. Then PRINCESS said to her best student TWILIGHT SPARKLE and she knew it. That TWILIGHT was worth creating. And then PRINCESS CELESTIA said someone else had to learn. TWILIGHT SPARKLE and her BEST FRIENDS watched as PRINCESS CELESTIA looked at the pony that was lying on the treadmill. And then PRINCESS CELESTIA said to the pony. CELESTIA: "WE HAVE TO STOP FIGHTING, SISTER." And then all six PONIES were surprised. ALL SIX: "SISTER?" PRINCESS CELESTIA. THE PRINCESS OF THE DAY was happy again that her youngest sister. PRINCESS LUNA. THE PRINCESS OF THE NIGHT was back.
