Dark Side of the Moon

S5, E16: Ambushed by angry hunters, Sam and Dean are shot and killed and sent to Heaven. Castiel warns Dean that Zachariah (guest star KURT FULLER) is looking for them in Heaven so they need to lay low while searching for an angel named Joshua (guest star ROGER AARON BROWN) who can help them since he talks directly to God. While searching for Joshua, the Winchester brothers run into some old friends and family members.
