Marcella's wayward brother Billy is coming out of rehab, restarting their sibling rivalry. She lands an audition but needs to cry for the role, and no matter what she tries the tears just will not come.

Marcella is thrilled to get a role in a film but her joy is short lived when her actions inadvertently cause the lead actress to have a meltdown. With filming cancelled she spends a giddy evening with Jon.

Marcella needs to tell her family about Billy's drug problem but can't bring herself to dent her mother's faith in her golden boy. Finding her hot-headed father as unhinged as usual she reluctantly turns to Simon for help.

A hungover and guilt-ridden Marcella has to face a date with Jon, while haunted by flashbacks from the night before - only to be called away thanks to Billy.
