There are two scenes in episode 9 of Big Love season 3 that were quite controversial, Barb going through the endowment ritual, and her exommunication. Both of these scenes are very accurate depictions of what really happens in mormonism. It is important to link the two storylines since Barb's impending excommunication is the reason she want to go to the temple one last time. This video is my attempt to give the context and show the relation between these two controversial scenes.
If you are sensitive to the depictions of the LDS Endowment ceremony please do not watch.
The 5th and final season of Big Love starts in January on HBO.
