A series of disasters threaten to derail Miri's first date with Billy. Meanwhile, Caroline & Oscar find a visitor on their doorstep and must finally reckon with Caroline's affair.

In the aftermath of Lara's vigil, Miri races back to Mandy's house to get ready for her date with Billy: the first proper date she has ever had in her life ever. But Mark intercepts her and pleads with Miri to find Mandy: she's supposed to be returning his waffle maker but his creepy phone tracking app says she's not at the store but at the lighthouse... Reluctantly, Miri heads out to look for her.

With the discovery of John at the lighthouse, it becomes clear that the road to Miri's first date will be a long and winding one.

Meanwhile in the Matteson House, Caroline and Oscar's bickering is interrupted by the doorbell. It's Dom and he needs a poo. Fearing what will happen if they leave him on their doorstep, the couple let him in.
