Pillow Fight

Inspired by a reviewer named LeviSkies and an alternate universe CM story called, "Puzzle Pieces" by DM's BabyGirl97. What if instead of having a cooking lesson at Rossi's, JJ tried starting a pillow fight between herself, Reid, Prentiss and Morgan at Reid's home to settle Reid's issue of JJ faking Prentiss' death and Morgan's issue of Prentiss' undercover secret with Doyle?
