If Nothing Trivial’s second season was about how to be in a relationship and how to avoid making the same old mistakes – then Season 3 is about how to be part of a family – in its various permutations. It’s also a lot about trust. Brian, the (mostly) reformed root rat is now father to baby Sonny Bill and is expecting a child with Emma. But can Emma forgive him for his betrayal and more importantly, can she ever trust him? Catherine and Mac are finally together, but they’re going into this with serious baggage, three children, a couple of exes - and parents who are in a relationship. And what exactly are they going into? Mac likes commitment, Catherine has always been wary - can they overcome their differences, and make the leap of faith to stay in love and truly be together? Michelle now has to learn to manage her condition, but how much of what’s her is chemical, and how much is personality? And can she win the trust of Richard enough to win him back?
