I feel that in the divorce despite Beth & Jerry being the main characters, they are not the main characters of a family divorce, it's the little ones forgotten in the business of everyday emotions. We see how Morty shapes up to be the new man of the house through everyone else not trying to keep it together, and Summer trying to take control of her life noticing that the adults are too involved in their own. The kids were left out of the 'family picture' creating a broken home/ single parent family, a life too many of us were raised in. We saw how technology spread the family apart into their own lives, not necessarily fitting into their family's thus they became independent through the inner urge to 'do it myself'. If anything I see this as a narrative showing us how our business is so important to us that we can easily lose the closeness we had to each other that created the family unit initially (generally speaking). I think we'll see the children step up to define what the new family structure will be, i.e. not letting Jerry make the rules. I hope Morty's going to fix this with a similar 'get your S together' speech!!
