Nic's lonely, and the cat's missing. Who is this new mum Jen, and what is Nic's secret?

The morning after their boozy night, Nic's paranoid about what she said to Jen, and putting a brave face on things for Ollie's birthday party isn't helping calm her nerves. Things improve slightly when Jen's dealer delivers a pick-me-up. Suzie comes round that evening to drop off Ollie's birthday present and discuss Alex's imminent anniversary with Dan; when Nic is showing Suzie out, she is shocked when Suzie makes it clear she doesn't trust her. The good news is the cat, Mr Miaowgi, has been found, but Nic's shocked to see her wedding album and video out.

Nic dreams about Alex and her coat and wakes to the realisation her coat is missing and she goes on a mission searching the house to find it; whilst searching she makes a shocking discovery in Ollie's bedroom. There's little time before school to talk to Ollie properly, and on the walk to school things get weird when Nic sees someone ahead wearing her missing coat. She's beyond stunned to realise it's Jen wearing her coat leading to an ugly, very public confrontation at the school gates.

Who is Jen, and who is Katya? It's time to reveal the truth about this new mum in town.

Copbury Hedgehog hunt is in full swing, but Jen's still missing, Nic is having more haunting visions and Dan is nervous about Alex's memorial; Lucy is desperate to know if Nic's watched any of her stand-up routine.

Nic's worried she's a bad mum and at Alex's memorial, the pressure mounts and truths will out.
