Morgan and Emily returned to the Bullpen to find Hotch, Garcia, JJ and the Reid's standing there waiting for them. They reported that they had found nothing except a half a cookie, and some crumbs leading them (probably to the other half) they said that the other half was in Rossi's office.
Hotch thought he had an idea of who might be the culprit behind these thieving's. Jack.
They all went up to Rossi's office and opened the door to find Jack, lying on the floor, doodling with Garcia's colouring things, Rachel's pen was lying next to him, all of Garcia's trolls were lined up along Rossi's desk and there were Emily's pad and Morgan's highlighters. Reid's coaster was being used to hold his cup of water.
'Jack!' Hotch exclaimed.
'Daddy?' Jack said, confused, but Hotch looked around to see the others smiling. But unfortunately none of them turned around in time to see the old man stood in the middle of the Bullpen watching them, a silvery-white glow surrounding him, and then he smirked. And walked through the desks, and away.
