The central message is that compassion within a strong extended family is important -- even if individual members don't always measure up to expectations. Some teens make bad choices but negative behaviors always have consequences. Storylines consistently show family members socializing and communicating with each other.
Some run-of-the-mill arguing, pushing -- and even bleeding -- when kids get into arguments or get injured, etc.
Some adult characters have sex with people outside of a committed relationship, and a few married characters admit to extramarital affairs. Teen characters consider becoming sexually active. No nudity, but some scenes imply sex has just taken place with bare shoulders peeking out of bedclothes, etc. Some lingerie shots.
Some mild swearing like "ass," "hell," "butt," and "motherfreakin'," etc.
Drinking, Drugs & Smoking
Two teen characters are arrested for smoking marijuana, and a teen smokes cigarettes; another is 19 and in Alcoholics Anonymous; he's working toward permanent sobriety. When teens drink underage, there are consequences. Adult characters also drink alcohol socially (and sometimes to excess) and, in at least one scene get high by accident.
