Fluttershy gets more than she asked for when she visits the Library and hears moaning from behind the door. Concerned that Twilight may have developed a problem, Rarity and Rainbow Dash go and investigate.

Everyone is dead. She doesn't know who is responsible, just that somepony activated the ultimate weapon. Only four ponies survived and now try to find meaning in the great wasteland. Celestia will just be happy if she can find a way to heal Twilight.

As Twilight Sparkle continues to go to Canterlot for private study sessions with Princess Celestia, she notices she feels less alone. This however raises more questions than it answers, forcing Twilight to figure out things she has never really even gave much thought to. Relationships. Love. Meanwhile, Princess Celestia has to struggle with her own emotions and fears, caused by centuries of loneliness and fear of getting too attached to anypony.

Friends who play together, stay together. That was the philosophy Rarity had in mind when she suggested she and Pinkie play a game of chess every week. Unfortunately for Rarity, however, Pinkie has a habit of changing the rules.

Fluttershy's son deals with many odd things on a daily basis. Such is the life of a teenaged colt living on the edge of the Everfree Forest.

However, as odd as Ponyville is, nothing is more odd than the events that surround the Elements of Harmony. Seeing as his mother is one of them, one must be certain to expect odd events occurring around the individual.

But when Fluttershy becomes "indisposed" for a day or two, can Choir Wings cover for his mother, without letting anypony know her secret?
