Somewhere in the temple itself, Castiel is doing the same thing. Sam's certain of that. But for the moment, he only has eyes for his Son.

His ears, though, catch the voices of other Hunters around them. The ones in the grove with them each intoning the prayer that Sam had spoken only moments before. He waits for them to finish before he begins speaking again, adding his voice to theirs and pulling their belief and hope into the spell that Gabriel works.
