Great episode. I am surprised that in 9 years of Grey's, the story of a Jehova's Witness hasn't been addressed before. I'm glad that Meredith is enjoying the pregnancy and I really hope they don't try and kill that storylline.
The relationship issues with Arizona and Callie were a little forced but relevant in order for them to deal with their patient. The future is definitely looking beak for SGMWH though.
Great episode. Although, some parts were below average. Nothing really big, but my patience wasn't at its best days. I really thought that Arizona was trying another tactic with that unbearable teen. Great move, Doctor! The story with that Jehova's Witness was really disturbing. I was totally submerged in mixed feelings.
What does its episode a big entertainment show is that sometimes, the last 5 seconds of each episode drops on you some intriguing questions. It's more like a bomb, that might explode on the next episode or not. Awesome!
