Sam and Dean break open the clay tablet they stole from Dick Roman causing a storm from which lightning strikes teenager Kevin Tran (guest star Osric Chau) and causes Castiel to wake up. Meg calls them and they arrive to find Castiel awake and with his memory intact, but insane. Castiel explains the tablet they found inside the clay is the Word of God, information from God written out on a tablet by Metatron, the celestial scribe, but he lacks the ability to read it.
At the same time, Kevin is driven to drive to the hospital where he steals the tablet before Sam catches him while Dean tries and fails to get answers from Castiel. Kevin displays the ability to read the tablet which contains information about the Leviathans, but has a hard time with it and two angels arrive to take him away, explaining that he is a Prophet chosen to interpret the Word and that he needs to be taken away to learn to do that. When they try to kill Sam and Meg, Castiel intervenes, but when they still refuse to stop, Dean banishes all three angels.
The group make their way to Rufus’ Cabin where they ward themselves from angels and have Kevin set to work on translating the tablet while Meg sneaks out and kills two demons that followed them. This draws the angels’ attention, but when one tries to kill Castiel, Meg kills her. The other angel allows Kevin to finish the translation before taking him away, but upon his return home, the two angels with him are killed by a Leviathan waiting for him. Sam and Dean discover that the tablet contains instructions on how to kill a Leviathan: “a bone of a righteous mortal washed in the three bloods of the fallen.” The first is a fallen angel and Castiel gives them a vial of his blood before disappearing.
