Plot summary
Crockett Island experiences a religious revival after Leeza suddenly regains the use of her legs, which residents regard as a miracle. Leeza visits Joe and tells him she has forgiven him for causing the injury that left her paralyzed, prompting Joe to attend an AA meeting with Riley and Paul. Sheriff Hassan becomes concerned when he learns his son Ali has been studying the Bible, and later unsuccessfully argues against Bev distributing Bibles at the public school. Paul suddenly collapses, coughing blood before dying in front of Bev and the Scarboroughs, only to revive moments later.
In a flashback, Paul reveals that Monsignor Pruitt became lost in a sandstorm near Jerusalem and took refuge in an ancient ruin, where he was attacked by a winged humanoid creature that drank his blood before feeding him its own. Pruitt awoke restored to his youth, revealing that Father Paul is actually a rejuvenated Pruitt. Convinced the creature is an Angel, Pruitt believes its blood is a divine gift he intends to share with the island.
