The CMC are on the lookout for something new and exciting in the hopes of getting their Cutie Marks. But they've never met anyone quite like DRWolf before. And he's never met anypony quite like the CMC either...
These two royal alicorns: cunning sun and gullible moon, go about their childish conversations and attitudes whenever nopony is looking-- well, except for a certain Purple alicorn. And you're involved, too.
Somepony seems to have thought it would help Discord with staying on the straight and narrow if he were required to send Celestia reports on friendship, like Twilight Sparkle does. Somepony was plainly out of their mind.
Scootaloo grew up and became fairly successful. However, still lacking her Cutie Mark, she gets depressed and talks to Luna in a late night dream about what her true destiny might be. Then Discord shows up and things get weird.
Luna rules the night. So when Celestia returns to the castle in a bad mood after Twilight's failed dinner party with Starlight, the night princess knows it is her duty to set her sister's mind at ease (as well as the minds of a few other friends).
