Rosie wakes up in the hospital following her brother's wedding where she served as best man and resolves to give up all her negative behaviours.

At the very moment Joey and Rosie seem to have made up, a tragedy occurs. Everyone takes it very hard, including Rosie. With Nico in tow, she goes back to her usual damaging behaviours, drinking excessively and seeking out kumquats on Deliveroo.

Still reeling, Rosie agrees to attend a rehab facility but at the last minute changes her mind and escapes, legging it into the nearby countryside.

Rosie accidentally takes meth and goes on an odyssey that involves befriending trees. She ends up at Ruby and Joey’s house - where she discovers something shocking.

Joey, Ruby, Nico and Win are not happy with Rosie having abandoned her attempt at rehab. After Rosie goes on the attack, she tries to confide in her mother.

Rosie panics that a failed drug test could get her fired and seeks to get her hands on a counterfeit urine sample. Rosie reveals she’s not the only one keeping secrets.
