Rarity had caught her sister and Button Mash in the act of their filthiness, but more wondered where she had learned such a thing. Sweetie Belle, who was quite embarrassed and covered in filth, told Rarity how she had watched her and AJ through the conveniently large keyhole to the janitor’s closet. Sweetie was only curious as to why they had gone in there, and was ultimately confused to what was right and wrong at this point. She described what she had saw to Rarity… the image was definitely interesting.
