When Sam, Dean, and Castiel learn that Michael has escaped from [[Hell]], Dean places a call to Donatello to see if he had felt a surge in God-like power, and tells him to let them know if he feels anything tickle his brain. While Donatello is doing his dishes, he feels a sudden surge in power as Michael [[Smiting|smites]] [[Lilith]] in a diner. Donatello calls Dean and describes Michael's energy as hurling around from place to place, eventually ending up in Cairo, Egypt. He ends their call by declaring his need for a bourbon.
