It's Spencer's birthday and he wants the whole family to go a zombie-themed hotel. But Dan and Courtney are not speaking and Jonathan and Claire are still awkward since the kiss.

Jonathan worries he has no friends, so makes the terrible decision to go for a night out with his boss Keith. Meanwhile Dan starts to reconsider having children.

Courtney unexpectedly goes into labour, whilst Jonathan attempts to make it up to Claire, and Spencer makes his own romantic gesture.

Jonathan spies on Claire’s boyfriend and goes on an actual real-life date. Dan and Courtney freak out over baby clothes. And Spencer goes berserk at jiu-jitsu to impress a girl.

Jonathan and his partner Claire are splitting up, but he’s desperate not to tell their son Spencer, so runs away with him to stay with his sister Danielle and her wife Courtney.

Jonathan lies to Claire about finding a new place to live for him and Spencer, giving himself just four days to find a flat.

When Spencer gets invited to a laser quest party, Jonathan is so distracted by over-parenting the situation that he risks embarrassing Spencer and losing his job.

When Claire invites a mysterious work colleague into her home, Jonathan worries that Spencer will end up with a new Dad. Meanwhile Dan and Courtney try to have a romantic night in.
