In Ponyville, it was well-known: Trouble had this weird tendency of following anypony who dared to poke their snout out of their house. The obvious countermeasure was to stay inside, lock the door, and throw away the keys. Something that sounded deliciously appealing for the princess of friendship. She couldn’t afford to get sidetracked by anything of lesser importance, for she had a brother to reconcile with, and that, that absolutely trumped anything and everything else. Ponies outside these crystalline walls will just have to learn to function with one of their princesses indisposed in the meantime.
