Great episode, they are all great. This one, however, I must say was not my favourite for a few reasons. I always love an episode with shocking or very unusual symptoms. This one did not really have much of either of these. This episode seemed to focus on more of the morals of the nuns' religion i think, or at least religion in general. I just did not find it all that interesting compared to the side stories of the others. This all changed when you found out the patient had been pregnant before and it instantly grew quite interesting.
The final reveal was awesome too, the way it was done it was like a punch in the face!! A copper cross just sitting in your body for so long, almost unimaginable.
