Castiel and Zachariah hold Dean captive, waiting for the apocalypse approaches. Dean pleads with Castiel to let him see Sam but Castiel refuses.

Later Castiel returns and apologises to Dean for deceiving him. Dean is angry, and argues with Castiel, trying to convince him to help them stop the apocalypse. He initially refuses but then returns, and cutting himself draws a sigil on the wall. Zachariah arrives to stop him, Castiel places a bloody hand on it and Zachariah is sent away. Castiel says he will take Dean to Sam to stop him killing Lilith - because her death IS the final seal.

Castiel and Dean visit Chuck Shirley who has forseen that Sam is at the Convent. An archangel arrives, and Castiel says he will hold it off and sends Dean directly to the Convent.
