There are many episodes with long serious kissing, but no nudity or unmarried kids in bed with each other. Joan's boyfriend never asked to go to bed with Joan (as another reviewer mentioned)

Joan's boyfriend wants sex and when Joan says no (every time he asks or it gets close) he gets frustrated.

Joan thought that God wanted her to have sex with her boyfriend (it didn't happen).

Making out between characters.

The police / detective portions sometimes include people who are beaten up or killed, but it is appropriate for the scene and not added just be violet or gory.

Joan's friend is murdered by her drug dealer.

One of the characters playing "God" is smoking and Joan takes the cigarette, looks at it with the "yuk" look, and tosses it out.

In one episode the criminal holds a gun to the head of Will (Chief of Police) while Will drives the car with the criminal telling where to go.

There is one episode where Joan's ex-boyfriend is lost in the woods. It is rainy and dark and might frighten younger viewers.
