The kids are growing up fast – Ava is now 10 and Luke is about to turn 13. With their burgeoning independence comes the question of whether Paul and Ally’s parenting style still works. Clue: no.

Luke’s anxiety is becoming a problem at home and school. Would a medical diagnosis make his life easier or harder? Ally faces further tension after her mother Leah is robbed.

Paul fears his culturally fragmented family has lost a vital connection. Gentrification impacts Jim and Jackie as the last of their old neighbours move out and more young professionals move in.

A sudden death impacts the older generation of the Worsley family. Ava struggles to keep a profound secret from Paul. Ally finds it difficult to hide her true feelings from Luke.

As Ally contemplates her pregnancy, a new piece of information blows her world apart. A worried Ava tries to help her mum while Luke regrets lying.

Ally is under huge pressure, but no one seems to want to listen to her; Jim and Jackie are excited about a possible move to the coast and, much to Paul's surprise, so is he.

Ally and Paul's marriage is in crisis. Paul's obsessed by what happened but won't discuss it. An increasingly troubled Luke refuses to go to school and Leah and Alex make an announcement.

As he and Ally continue to feel distant, Paul rekindles an old friendship, but at a cost to Ava. Luke surprises everyone by getting a best friend. Jim and Jackie are forced to move.

As Jim and Jackie's golden wedding anniversary party is plunged into darkness by a power outage, the growing tensions between Paul and Luke reach an explosive and terrifying climax.

On the day of Leah and Alex's wedding, Paul and Ally find they have only a few hours to deal with a family crisis, leading Paul to make the hardest decision of his life.

The children won’t sleep – Paul and Ally thought these nights were over. Paul spends the night fighting his own anger and his children’s inability to go the f**k to sleep.

Luke's parents and the surprising arrival of Ally's estranged father cause Paul and Ally to scrutinize their hopes and dreams for Luke and Ava and discover how far they will go for the sake of their kids.

Ally attempts to acclimatize to Michael's continued presence while Paul begins to question if his accident-prone son's frequent injuries might actually be his fault.

Michael thrives in his new role as dad and granddad, but Paul and Ally can't adapt to his presence as easily as the children can. Luke's hunt for proof that Santa doesn't exist puts Paul's claim that he never lies to the test.

Paul and Ally are thrilled that Sprout the family gerbil has finally died, but explaining loss to Luke and Ava is more difficult than they thought as grief manifests itself in mysterious ways and throws the family off course.

In the wake of Michael’s death, the family stay with Darren at his country house, but Paul’s attempt to give Ally space by taking on kid duties and Darren’s fixation on work doesn’t help Ally find a chance to say goodbye.

It’s half term and Luke is responsible for taking Lenny the class bear on an adventure. Lenny has been to Italy, Peru and beyond, but Paul can’t even manage to get the family and the godforsaken bear out of the house to the local park.

Paul attempts to focus on his upcoming wedding but is constantly thwarted by his family; Ally is distracted by work, Luke is misbehaving at school and Leah (Stella Gonet) doesn’t understand why they are even bothering to get married.

Family life is thrown off kilter as Ally spends her weekdays in Berlin and weekends in London. Paul, Luke and Ava try to muddle through without her, but the children aren’t sleeping again and it takes its toll on Paul.

Luke’s condition worsens and he is admitted to a specialist pediatric unit. As Paul, Ally and their parents desperately wait for news, stress and fear cause cracks to form within the family.
