Well, arguably the single biggest topic of all: God.
Dres top-of-episode musing this week is about constants.
A slightly more relevant constant is how much Dre hates his in-laws, especially Johan.

By this she means world hunger, cancer, dead babies.
Johan thinks Zoey is on the right track.
In other words, the black workers believe in God, and the white bosses dont.

Johann seems to think those huge hospital A/C units probably account for that.
NEXT: A real crisis of faith
Dres attempts to save Zoey grow increasingly more desperate.
Zoey thinks this behavior is unworthy of her father and leaves him.
For his next attempt, Dre recruits Ruby to drive the fear of God into Zoey.
After this, Dre turns his anger inward.
Are Zoeys doubts the result of his own fractured relationship with God?
Did his own faith waver to the point he wasnt able to provide a convincing example for his children?
Seeking answers, Dre turns to the man himself with a deep prayer.
Naturally, he cant keep himself from getting distracted.
Then he smells kettle corn.
Speaking of which, its time for Bows next sonogram, and she brings the whole family along.
Here the episode flirts with some true darkness when the doctor has trouble finding the babys heartbeat.
False alarm: The fetus heartbeat is found!
Johan, by contrast, is alone in the living room drinking wine.
Were not privy to his secular thoughts.
